Watercolour pans can be time-consuming to dry, and the process can be frustrating for artists who are eager to continue working on their pieces. The drying time depends on factors such as paint thickness, water content, ambient temperature, and humidity. To speed up the process, some artists recommend using a hairdryer on a low setting, placing the pans in the sun, or using a food dehydrator. Others suggest adding a drying agent like silica packs, rice in a sealed container, or glycerin to the pans. It's important to note that different brands of paint dry differently due to variations in their ingredients.

What You'll Learn
Use a hairdryer on a low setting
Using a hairdryer on its lowest setting is an effective way to dry watercolour pans faster. This method can be especially useful if you are an impatient artist who wants to keep working on a piece without waiting for the paint to dry naturally.
Firstly, make sure you remove any nozzles from the hairdryer before you begin. Then, set the hairdryer to its lowest heat and speed settings to avoid damaging or warping the paper or causing the paint to crack. Too much airflow may also cause the paint to splatter across the paper.
Hold the hairdryer around 6-8 inches away from the paper to avoid overheating it, which may cause the paper to wrinkle or buckle. Position the dryer directly above the paper instead of at an angle to avoid blowing the paint into the wrong area.
Move the hairdryer back and forth over the paper to distribute the heat evenly and prevent overheating in one spot. As you go, keep testing the paint with a fingertip to check that it is drying evenly.
Once the paint is dry, it is important to let the paper cool fully before adding more layers of paint. This will prevent the paint from cracking.

Place pans in direct sunlight
Placing your pans in direct sunlight is a great way to speed up the drying process. The heat from the sun will evaporate the water from the pans, leaving them dry and ready to use. This method is not only free but also environmentally friendly.
However, it is important to note that some artists advise against leaving watercolour pans in the sun to dry. This is because the UV rays from the sun may alter the colours of your watercolour palette. If you are creating a professional piece, this method may not be suitable as it could affect the final product.
Additionally, the sun may not always provide consistent heat, and the drying time may vary depending on the weather conditions. If you are in a rush, using direct sunlight to dry your pans may not be the most efficient method.
To use this method effectively, place your pans in an area that receives direct sunlight. Ensure that the pans are secure and will not be disturbed by wind or other elements. Leave the pans in the sunlight for several hours, checking on them periodically to assess their dryness.
It is important to note that the drying time will depend on various factors, including the thickness of the paint, the amount of water used, and the ambient temperature and humidity. Therefore, the exact drying time when using direct sunlight may vary.

Use a food dehydrator
Using a food dehydrator is an innovative way to dry your watercolour pans faster. This method is particularly useful if you are in a hurry and don't have a week to wait for your pans to set. It is also a good option if you are travelling with your paints and need them to be dry for your journey.
Firstly, it is important to note that you should avoid melting the pans with excessive heat. If your food dehydrator has temperature settings, a temperature of 35°C (95°F) is recommended. If your dehydrator does not have temperature settings, keep a close eye on your pans to ensure they do not overheat.
The length of time needed to dry the pans will depend on the brand of paint and the amount of paint in each pan. One source suggests that it takes approximately 8 hours for pans that are filled a third full to dry at 35°C.
If you are using honey-based paints, be aware that they will remain wet between each painting session. This is something to consider when choosing a drying method, as it may be a recurring issue.
Using a food dehydrator is an effective way to dry your watercolour pans quickly, ensuring they are ready for use or travel.

Add a drying agent like rice
If you want to dry your watercolour pans faster, one option is to use a drying agent like rice. This method is simple and convenient, as it does not require any special equipment or techniques. Here is a step-by-step guide on how to do it:
Firstly, prepare your rice. It is recommended to use uncooked rice, as cooked rice may not absorb moisture as effectively. Rinse the rice thoroughly under running water to remove any dust or impurities. Then, drain the rice and spread it out on a clean cloth or paper towel to air-dry completely before using it to dry your watercolour pans.
Next, choose an appropriate container that is large enough to hold your watercolour pans and has a tight-fitting lid. A sealed container is essential to ensure that the rice does not absorb excess moisture from the surrounding environment, which could affect its drying capacity. Glass or plastic containers with secure lids are good options.
Now, fill the container with a layer of rice. The layer should be thick enough to provide adequate coverage for your watercolour pans. Place your pans on top of the rice, making sure they are not stacked or crowded together, allowing air to circulate freely around each pan.
After that, seal the container tightly and store it in a cool, dry place. The rice will help absorb moisture from the watercolour pans, speeding up the drying process. Depending on the humidity and the number of pans, you may need to replace the rice periodically to maintain its drying efficiency. Check the rice every few days and replace it if it feels damp.
Finally, once your watercolour pans are completely dry, remove them from the rice and store them in a cool, dry place. You can reuse the rice for future drying purposes, but it is essential to ensure it is completely dry before using it again. This method is a natural and cost-effective way to dry watercolour pans faster, making it a convenient option for artists who want to speed up the drying process without relying on artificial agents.

Fill pans in sections
Filling pans in sections is a good way to ensure your watercolour pans dry thoroughly. This method is especially useful if you are using half pans. Firstly, it is important to note that different brands of paint dry differently, depending on the ingredients used in the paint formula. For example, Schmincke Watercolours do not need glycerine, while other brands may need one or two drops. Glycerine is a plasticizer that makes the paint less brittle and reduces cracking when it dries.
When filling pans in sections, start by adding a small amount of paint to the pan and allowing it to dry completely before adding more. This way, you can ensure that the paint is thoroughly dried between each layer. The number of sections will depend on the size of your pan and the amount of paint you are using. For half pans, you can fill them in two or three stages, allowing each layer to dry before adding more paint.
It is normal for watercolours to shrink as they dry, so filling in sections can help to prevent this. By allowing each layer to dry completely, you can also avoid the problem of the paint sticking to the lid of the palette or becoming too sticky.
When filling your pans, it is also important to consider the type of paint you are using. Tube watercolours are made up of coloured pigments and a liquid that holds the pigments in suspension. This liquid contains ingredients that affect the drying characteristics of the paint when put into pans.
