Ever crafted a magnificent papier-mâché masterpiece only to be met with the agonizing wait for it to dry? It’s a familiar frustration for seasoned crafters and enthusiastic beginners alike. The truth is, there’s no single magic number for papier-mâché drying time. Instead, it’s a delicate dance between several factors that can significantly influence the process. From the type of paste used to the environmental humidity, and, of course, the thickness of your creation, each element plays a crucial role in determining just how long you’ll be twiddling your thumbs before adding the finishing touches. So, if you’re eager to unravel the mysteries of papier-mâché drying and discover how to speed up the process, read on. We’ll delve into the science behind the dry time, exploring the variables at play and offering practical tips for ensuring your projects dry efficiently and beautifully.
Firstly, let’s consider the impact of the adhesive you choose. While traditional flour-and-water paste is a popular and cost-effective option, it tends to have a longer drying time compared to other alternatives. This is due to its higher water content, which requires more time to evaporate. Consequently, projects using flour-and-water paste may take anywhere from 24 to 72 hours to dry completely, particularly in humid environments. Alternatively, using a glue-based paste, like white glue mixed with water, can significantly shorten the drying time. The lower water content in glue-based pastes allows for quicker evaporation, often resulting in drying times of 12 to 24 hours. Furthermore, the thickness of the papier-mâché layers significantly influences the drying process. Thicker layers naturally hold more moisture, therefore requiring a longer drying period. Conversely, applying thin, even layers allows for faster evaporation and a quicker overall drying time. Therefore, patience and meticulous application are key to achieving a smooth and efficiently dried finished product.
Finally, the environment plays a critical role in papier-mâché drying. Humidity, temperature, and airflow all contribute to the speed of evaporation. In humid environments, the air is already saturated with moisture, making it difficult for the water in the papier-mâché to evaporate. This can significantly prolong the drying time, potentially leading to mold growth if not addressed. Conversely, warm, dry environments with good airflow facilitate faster evaporation, resulting in shorter drying times. Therefore, placing your project in a well-ventilated area, perhaps near a fan or in a room with low humidity, can drastically expedite the drying process. Moreover, consider rotating your project regularly to ensure even drying on all sides. By carefully considering these environmental factors and employing appropriate drying techniques, you can ensure your papier-mâché creations dry efficiently and beautifully, ready for the final flourish of paint and decoration.
Understanding Drying Times for Papier-Mâché Projects
So, you’ve crafted a magnificent papier-mâché masterpiece, and now you’re staring at it, wondering, “When on earth will this thing dry?” It’s a common question, and the answer, like most things in the art world, isn’t always straightforward. Several factors play a role in determining the drying time, and understanding them can save you from a lot of frustration (and potentially a soggy mess). Let’s dive into the key elements that influence how long your papier-mâché creation takes to fully dry.
First up is the thickness of your layers. Think of it like this: a thin sheet of paper dries much faster than a thick stack. The same principle applies to papier-mâché. If you’ve built up your project with many layers, especially thick ones, it will naturally take longer to dry. Each layer adds to the overall mass of wet paste and paper, meaning more moisture needs to evaporate. Thicker projects can sometimes take several days to dry completely, so patience is key.
Next, consider the type of paste you used. Traditional flour and water paste tends to dry a bit slower than some store-bought adhesives specifically designed for papier-mâché. These specialized pastes often contain ingredients that promote faster drying. If you opted for the homemade route, don’t worry, it will still dry beautifully; just give it a little extra time.
The surrounding environment plays a crucial role as well. Humidity is your enemy here. A humid environment makes it harder for the moisture to evaporate, significantly lengthening the drying process. On the other hand, a warm, dry, and well-ventilated area is ideal. A gentle fan can also help circulate the air and speed things up, just be careful not to point it directly at your project, as this could cause warping or cracking, especially in the early stages of drying.
The size and shape of your creation also contribute to the drying time. A small, simple object will obviously dry much quicker than a large, complex sculpture with lots of nooks and crannies. Intricate shapes can trap moisture, making it harder for the air to reach those areas and dry them effectively. If you’re working on a larger project, consider allowing extra drying time between layers. This not only helps prevent warping but also ensures each layer dries properly before adding more, ultimately leading to a stronger and more stable finished piece.
Finally, the type of paper used can have a subtle impact. Thicker papers, like cardstock, hold more moisture and will therefore take longer to dry compared to thinner papers like tissue paper. While the difference might not be dramatic, it’s still something to keep in mind.
Factors Affecting Drying Time
| Factor | Impact on Drying Time |
|---|---|
| Thickness of Layers | Thicker layers = Longer drying time |
| Type of Paste | Homemade paste (flour and water) = Longer drying time |
| Humidity | High humidity = Longer drying time |
| Size and Shape | Larger, complex shapes = Longer drying time |
| Type of Paper | Thicker paper = Longer drying time |
How to Check for Dryness
Knowing when your papier-mâché is completely dry requires a bit of detective work. A visual inspection is a good starting point. The color of the paper will lighten as it dries, so look for any remaining dark or damp patches. But looks can be deceiving. Sometimes the surface might appear dry while the inner layers are still damp.
The touch test is your best bet. Gently press on different areas of your project, especially thicker sections. Does it feel cool to the touch? That’s a sign of lingering moisture. If it feels room temperature and firm, then you’re likely in the clear. You can also try tapping the piece; a hollow sound indicates dryness, while a dull thud suggests it needs more time.
Tips for Faster Drying
While patience is a virtue, there are ways to encourage faster drying. Placing your project in a warm, dry, and well-ventilated area is key. Avoid damp basements or humid bathrooms. A gentle fan can circulate the air, but avoid pointing it directly at your project, especially in the early stages, to prevent warping. Turning your project regularly also ensures even drying. And, as mentioned earlier, using thinner layers and allowing sufficient drying time between each layer can significantly speed up the overall process.
Factors Influencing Papier-Mâché Drying Time
Creating with papier-mâché is a rewarding experience, but patience is key, especially when it comes to drying. Several factors play a role in how long your masterpiece takes to fully dry, from the environment to the materials themselves. Understanding these factors can help you plan your project and avoid any sticky situations.
Number of Layers
Think of it like this: a single sheet of paper dries quickly, right? But a stack of damp paper? Not so much. The same principle applies to papier-mâché. The more layers you add, the longer the drying process takes. Each layer traps moisture beneath it, and that moisture needs time to evaporate. A thin, delicate project with just a few layers might dry overnight, while a bulky sculpture with numerous layers could take several days, or even a week, to dry completely.
The thickness of each layer also contributes to the overall drying time. Thick, gloppy layers hold more moisture than thin, evenly spread layers. So, while building up your creation, aim for thin, even coats to minimize drying time. Applying too much paste can also prolong the drying process, as it adds extra moisture to the mix. It’s better to use less paste and ensure each layer is thoroughly saturated but not dripping.
Consider the shape and size of your project, too. A small, simple shape with fewer crevices will dry faster than a large, complex creation with lots of nooks and crannies. Air circulation plays a vital role, and those hard-to-reach spots can trap moisture, slowing down the drying process. To expedite drying, try to provide as much air circulation as possible by rotating your project regularly.
Here’s a general guideline to help you estimate drying times based on the number of layers:
| Number of Layers | Estimated Drying Time |
|---|---|
| 1-3 | 12-24 hours |
| 4-6 | 24-48 hours |
| 7-10 | 48-72 hours |
| 10+ | 72+ hours (possibly up to a week) |
Keep in mind that these are just estimates, and actual drying times can vary depending on the other factors we’ll discuss.
Type of Adhesive
Your choice of adhesive can significantly impact drying time. Traditional flour-and-water paste is a popular choice and dries relatively quickly. However, white glue (like PVA) tends to create a more water-resistant finish and can take a bit longer to dry. Wallpaper paste is another option and generally dries slower than flour-and-water paste. Experimenting with different adhesives can help you find the best balance between drying time and the desired finish for your project. For instance, if you’re working on a project that requires a strong, water-resistant finish, you might be willing to accept a longer drying time with white glue. Conversely, for a quick craft project, flour-and-water paste might be the perfect choice.
Environmental Factors
Think of your papier-mâché project as a little sponge. Just like a sponge dries faster in a warm, sunny room than in a cold, damp basement, your project’s environment greatly influences drying time. Warm temperatures, low humidity, and good air circulation are ideal for quick drying. A sunny windowsill, a warm, dry room, or even using a fan can significantly speed up the process. Conversely, cold temperatures, high humidity, and poor air circulation can slow things down considerably. Avoid placing your project in damp areas or directly on cold surfaces. If you’re working in a humid environment, a dehumidifier can help create a more conducive drying atmosphere. Even small changes in temperature and humidity can have a noticeable impact on drying time.
The Role of Humidity and Temperature
When it comes to papier-mâché drying times, humidity and temperature play a significant role. Think of it like this: you’re trying to get water to evaporate from your project. Higher humidity means the air is already saturated with moisture, making it harder for the water in your papier-mâché to escape. Conversely, lower humidity means the air is drier and can absorb more moisture, leading to faster drying. Similarly, higher temperatures encourage faster evaporation, while lower temperatures slow it down. It’s a delicate balance, and understanding how these factors interact can help you predict and even control drying times.
Temperature’s Impact on Drying
Temperature acts like a catalyst for the evaporation process. Warmer temperatures give the water molecules in the paste more energy to escape into the air as vapor. This translates to quicker drying times. Imagine leaving a puddle of water out in the sun on a hot day – it disappears much faster than on a cool, cloudy day. The same principle applies to papier-mâché. A warmer room will significantly speed up drying, while a cool room will slow things down considerably.
Humidity’s Influence
Humidity measures the amount of water vapor already present in the air. High humidity means the air is already pretty full of moisture and has less capacity to absorb more. This creates a slower drying environment for your papier-mâché project. Think of it like trying to pour more water into a glass that’s already full – it just won’t go. Low humidity, on the other hand, means the air is dry and thirsty, ready to absorb moisture, leading to faster drying.
The Interplay of Temperature and Humidity and Optimal Drying Conditions
The relationship between temperature and humidity is crucial in determining the ideal drying conditions for papier-mâché. While warm temperatures generally speed up drying, high humidity can counteract that effect. Imagine trying to dry your project on a hot, humid day. Although the heat encourages evaporation, the air’s saturation with moisture hinders the process, potentially leading to longer drying times and even warping or mold growth. Conversely, a cool, dry environment, while slower, provides more consistent drying and minimizes the risk of warping. The sweet spot is a warm, dry environment. This combination provides the optimal conditions for efficient and even drying. A temperature between 70-75°F (21-24°C) and a relative humidity of around 50% is generally considered ideal. This balance allows for relatively quick drying without excessive moisture that could lead to problems. However, these are just guidelines. You might need to adjust based on your specific project and the climate you’re in. Experimentation is key, and observing your project as it dries will give you the best insight into what works best.
To further illustrate this relationship, consider the following table:
| Temperature | Humidity | Expected Drying Time | Potential Issues |
|---|---|---|---|
| Low | Low | Slow (2-3 days or more) | May take excessively long, particularly for thicker pieces |
| Low | High | Very Slow (3+ days) | Increased risk of mold, warping, and uneven drying |
| High | Low | Fast (1-2 days) | Optimal drying, minimal risk of issues |
| High | High | Moderate (2+ days) | Potentially uneven drying, slight risk of warping |
Tips for Managing Humidity and Temperature:
You can influence the drying environment to some degree. Using a fan can help circulate the air and speed up drying, even in humid conditions. A dehumidifier can help reduce excess moisture in the air, creating a drier environment. Conversely, if you’re in a very dry environment, you might want to slow down the drying process to prevent cracking by covering the project loosely with plastic.
Drying Times for Different Papier-Mâché Techniques
Layering Method
The classic layering method involves applying strips of paper soaked in paste onto a form (like a balloon or armature). Drying time for this method is heavily dependent on the thickness of the paper, the number of layers, the type of paste used, and the ambient humidity and temperature. Generally, you can expect each layer to take anywhere from 2 to 24 hours to dry thoroughly. For thinner layers with a simple white glue paste, drying might be quicker, whereas thicker layers or those using flour-based paste can take significantly longer. To ensure complete drying, allow at least 24 hours for a moderately layered piece and up to several days for thicker, more complex projects.
Pulp Method
The pulp method involves blending paper into a pulp and molding or sculpting it into the desired shape. This method tends to dry more slowly than the layering method because the pulp contains more water. The drying process can take anywhere from a couple of days to a week or more, depending on the thickness and size of the object and the environmental conditions. Thicker sections will naturally take longer to dry completely.
Combining Methods
Some projects might benefit from combining the layering and pulp methods. For example, you could create a base structure using the pulp method and then add details or refine the shape using the layering method. The drying time will depend on the thickness of each section and the methods used. It’s essential to let the pulp base dry thoroughly before adding layers to prevent warping or cracking. This could mean waiting several days before proceeding with the layered sections.
Cardboard Base with Papier-Mâché
This method provides a sturdy, quick-drying foundation, making it a popular choice for many projects. The cardboard base itself doesn’t require drying time in the same way papier-mâché does. However, once the papier-mâché layers are applied, drying times are similar to the traditional layering method. The advantage of using a cardboard base is that you often need fewer layers of papier-mâché to achieve the desired shape and strength. This can significantly reduce overall drying time. A single layer over a cardboard base may dry in as little as a few hours in a dry, warm environment. Multiple layers may still require 24-48 hours for complete drying, particularly with thicker applications or in humid conditions.
The table below provides a general overview of drying times based on the number of papier-mâché layers applied over a cardboard base:
| Number of Layers | Estimated Drying Time (in hours) |
|---|---|
| 1-2 | 4-12 |
| 3-5 | 12-24 |
| 6+ | 24-72 |
These times are estimates and can vary depending on factors like the type of paste used, the thickness of the layers, and environmental conditions. It’s always best to err on the side of caution and allow ample drying time to prevent mold growth or warping. You can check for dryness by gently tapping the surface. A hollow sound indicates that the piece is likely dry. You can also check for dampness by feeling the inside of the piece if accessible.
For complex shapes with intricate details, strategically positioning the piece for optimal airflow can help accelerate the drying process. Avoid placing the piece in direct sunlight or near heat sources, as this can cause cracking. A well-ventilated area at room temperature is ideal. Using a fan on a low setting can also help circulate air and promote even drying.
How Long Does Papier-Mâché Take to Dry?
Papier-mâché, a beloved craft medium for its versatility and affordability, involves layering paper soaked in adhesive to create various forms. A common question that arises when working with this medium is, “How long does it take to dry?” The truth is, there’s no single, definitive answer. Drying time depends on several factors, including the thickness of the layers, the type of adhesive used, the humidity levels in your environment, and the overall size and shape of your project. Generally, you can expect anywhere from 24 to 72 hours for a standard papier-mâché project to dry completely.
Expediting the Drying Process: Tips and Tricks
While patience is a virtue, sometimes you need your papier-mâché creation to dry a little faster. Luckily, there are several strategies you can employ to speed up the process without compromising the integrity of your project.
Air Circulation
Good airflow is key to quicker drying. Avoid enclosing your project in a confined space. Instead, place it in a well-ventilated area, perhaps near an open window or fan. A gentle breeze can significantly reduce drying time. Just be sure the fan isn’t too powerful, as this could warp delicate shapes.
Low Humidity
High humidity can slow down the drying process significantly. If you live in a humid climate, consider using a dehumidifier or placing your project in a room with lower humidity, like a bathroom with the exhaust fan running. Aim for a dry environment to encourage faster evaporation of the moisture.
Thin Layers
Applying thin layers of papier-mâché is crucial for faster drying. Thick layers trap moisture, prolonging the drying time. It’s better to build up your form gradually with multiple thin layers rather than a few thick ones. This method not only reduces drying time but also creates a stronger, more durable finished product.
Heat Sources (Use with Caution!)
Optimal Temperatures and Safety Precautions
Using heat can accelerate the drying process, but it requires careful monitoring. A low-heat oven (around 150-200°F or 65-95°C) can be used, but it’s essential to check regularly to prevent burning or warping. Avoid using a microwave as the uneven heating can cause damage. An even better alternative is a low-watt incandescent bulb placed a safe distance from the project. The gentle heat emitted by the bulb helps to dry the papier-mâché without the risk of scorching.
Placing your project in direct sunlight can also speed up drying, particularly on warm, sunny days. However, be mindful of intense sunlight, which could cause fading or cracking. Consider placing your project in partial shade to get the benefits of the sun’s warmth without the risk of damage.
A hair dryer on a low, cool setting can also be used for spot drying or for smaller projects. Keep the dryer moving constantly to prevent overheating any particular area. Avoid using hot settings as this can lead to warping or even burning of the paper.
It’s essential to remember that heat should be used with caution. Always monitor your project closely when using any heat source to ensure it doesn’t overheat or become damaged. Prioritize safety and patience, and your papier-mâché creations will dry beautifully.
| Method | Pros | Cons |
|---|---|---|
| Air Circulation (Fan) | Gentle, effective for most projects | Can warp delicate shapes if too strong |
| Low Humidity (Dehumidifier) | Significantly reduces drying time | Requires a dehumidifier, can be expensive |
| Low Heat (Oven, Light Bulb) | Fast drying | Risk of burning or warping if not monitored carefully |
| Sunlight | Free, effective on warm days | Risk of fading or cracking in intense sunlight |
Type of Adhesive
The type of adhesive used can also influence drying time. White glue, often mixed with water, is a popular choice and dries relatively quickly. Paste, while strong, tends to take longer to dry. Experiment with different adhesive ratios to find a balance between drying time and the desired strength of your project.
Determining if Your Papier-Mâché is Completely Dry
Knowing when your papier-mâché creation is completely dry is crucial for the next steps, whether it’s painting, varnishing, or simply admiring your handiwork. Impatience can lead to a sticky mess, or worse, mold growth if sealed prematurely. So, how can you tell when your project is truly ready? Here’s a comprehensive guide to help you determine dryness.
The Visual Check
Start with a good visual inspection. Look closely at the surface of your papier-mâché. A damp piece will appear darker than when dry, almost as if the color is saturated. As it dries, the color will lighten and become more uniform. Look for any noticeably darker patches, which indicate remaining moisture. This is especially important in thicker areas or intricate details where moisture can linger.
The Touch Test
Gently touch the surface of your papier-mâché. Does it feel cool to the touch? Damp papier-mâché will feel cooler than the surrounding air. If it feels room temperature, it’s a good sign that the drying process is well underway. Now, press gently with your fingertip. Does it give at all? Any softness or give indicates trapped moisture. A completely dry piece will be firm and rigid, offering no resistance to gentle pressure.
The Weight Test
If you’re working on a smaller piece, try the weight test. Pick up the object and feel its weight. A wet or damp piece will feel noticeably heavier than a dry one. As the water evaporates, the piece will become lighter. This method is most effective if you’ve handled the piece throughout the drying process, giving you a sense of its changing weight.
The Sound Test
For hollow papier-mâché objects, try the sound test. Gently tap the surface. A damp piece will sound dull and thud-like. As it dries, the sound will become hollower and more resonant. This method works particularly well for bowls, masks, or other enclosed shapes.
The Time Factor
While not a definitive test in itself, understanding the factors influencing drying time can help manage expectations. Thicker layers, humid environments, and complex shapes all contribute to longer drying times. A small, thin piece might dry in a day or two, while a larger, thicker project could take a week or even longer. Don’t rush the process! Patience is key to achieving a perfectly dry, durable finish.
The Detailed Drying Time Exploration
Drying time for papier-mâché isn’t a one-size-fits-all answer. Several factors influence how quickly the moisture evaporates, and understanding these variables can save you from frustration and potential project mishaps. Here’s a deeper dive into the key factors:
Thickness of Layers: The more layers of paper you apply, the longer it takes to dry. Think of it like a sponge—a thin sponge dries much faster than a thick one. Multiple thin layers, applied with proper drying time between each, are preferable to a few thick, gloppy layers. This allows for even drying and prevents trapped moisture.
Environmental Humidity: Humidity plays a significant role in drying time. High humidity slows down evaporation, meaning your project will take longer to dry. In dry climates, drying happens much quicker. Consider using a fan or placing your project in a well-ventilated area to promote air circulation and speed up the drying process, especially in humid environments.
Temperature: Warmer temperatures generally accelerate drying. Avoid placing your project in direct sunlight, as this can cause warping or cracking, especially in thicker pieces. Gentle, indirect heat, like the warmth from a radiator, can be helpful.
Project Size and Shape: Intricate shapes with lots of nooks and crannies take longer to dry as air circulation is restricted. Larger projects, simply due to their volume, also require more drying time. Be patient with larger and more complex pieces, regularly checking for dryness.
Type of Adhesive: The type of adhesive used can also influence drying time. A paste made with flour and water tends to dry slower than a white glue mixture. Experiment with different adhesives to find what works best for you, keeping in mind the drying time implications.
| Factor | Impact on Drying Time |
|---|---|
| Thick Layers | Increases drying time significantly |
| High Humidity | Increases drying time |
| Low Humidity | Decreases drying time |
| High Temperature | Decreases drying time (but avoid direct sunlight) |
| Large Size/Complex Shape | Increases drying time |
| Flour and Water Paste | Generally slower drying time |
| White Glue Mixture | Generally faster drying time |
Troubleshooting Common Drying Issues
Sometimes, your papier-mâché project might seem to take forever to dry. This can be frustrating, especially if you’re eager to move on to painting or decorating. Here are some common drying problems and how to fix them:
Thick Layers
Applying really thick layers of papier-mâché is a common culprit for extended drying times. Think of it like this: each layer of paste-soaked paper adds to the overall moisture content. Lots of layers mean lots of moisture to evaporate. While thicker layers can give you a sturdier finished product, they significantly increase drying time and can even trap moisture inside, leading to mold or a musty smell.
Humid Environments
High humidity makes it harder for the water in the paste to evaporate. It’s like trying to dry your clothes outside on a damp day. The air is already saturated with moisture, so the water in your project has nowhere to go. If you live in a humid climate, or you’re crafting during a particularly damp spell, your papier-mâché will naturally take longer to dry.
Insufficient Air Circulation
Good airflow is crucial for drying papier-mâché. Just like a gentle breeze helps dry your laundry, air circulation around your project encourages evaporation. If your project is tucked away in a closed container or a stuffy room, the air around it becomes saturated with moisture, slowing down the drying process considerably.
Using the Wrong Paste
The type of paste you use can also affect drying time. A very watery paste will obviously add more moisture to the project, prolonging drying. Heavier pastes, like those made with cooked flour or wallpaper paste, can take longer to dry than lighter pastes. Conversely, some store-bought pastes are formulated for faster drying.
Type of Paper Used
Believe it or not, the type of paper you use can make a difference. Thicker papers, like cardstock, absorb more paste and therefore take longer to dry. Newspaper, a classic papier-mâché material, is relatively thin and dries fairly quickly. Experimenting with different paper types can help you find the balance between strength and drying time.
Incorrect Drying Techniques
Leaving your project to dry in direct sunlight might seem like a good idea, but it can actually cause warping and cracking, particularly with larger pieces. Likewise, placing it on a radiator or using a hairdryer can dry the outer layers too quickly, trapping moisture inside. This can lead to uneven drying, structural weakness, and even mold growth.
The Ultimate Guide to Drying Papier-Mâché
Getting your papier-mâché projects to dry efficiently and effectively is key to a successful crafting experience. Here’s a breakdown of how to avoid common pitfalls and ensure your creations dry beautifully:
Thin, Even Layers: Apply thin, overlapping layers of paper. Resist the urge to build up thickness quickly. Patience is key here! Think of it like building a brick wall – thin, even layers create a stronger and faster-drying structure.
Ideal Drying Environment: Find a warm, dry spot with good air circulation. A well-ventilated room is perfect. If humidity is high, consider using a dehumidifier or placing a fan nearby to gently circulate the air. Avoid extremes of temperature, as this can cause cracking.
Drying Time: Papier-mâché can take anywhere from 24 hours to several days to dry completely, depending on the factors mentioned above. Regularly check your project for dampness. A good test is to gently tap it – a hollow sound indicates dryness.
Elevated Drying: Elevate your project slightly to allow air to circulate underneath. You can use a wire rack, a few small blocks of wood, or even crumpled newspaper. This prevents moisture from being trapped against a flat surface.
Turning Regularly: For larger or more complex projects, turning them regularly exposes all sides to the air, promoting even drying. This is particularly helpful for preventing warping or uneven drying.
Troubleshooting Tips: If your project feels damp after several days, try moving it to a drier location or increasing air circulation. If you suspect trapped moisture, carefully poke a few small holes in an inconspicuous area to allow the moisture to escape.
| Problem | Solution |
|---|---|
| Thick Layers | Apply thin, even layers of paper. |
| Humid Environment | Use a dehumidifier or fan. |
| Insufficient Air Circulation | Dry in a well-ventilated area, elevate the project. |
| Wrong Paste | Experiment with different pastes to find one that dries quickly. |
