Did You Know?
1. The concept of a damp box for pottery actually dates back to ancient Egypt, where clay pots were often stored in sealed boxes to maintain a consistent moisture level and prevent drying during the shaping and drying processes.
2. Did you know that a damp box can also be used for other crafts besides pottery? Artists working with materials such as paper, leather, or even woodcarving often utilize damp boxes to keep their materials moist and pliable, allowing for easier manipulation and shaping.
3. Building a DIY damp box doesn’t have to be complicated! A simple and cost-effective way to create one is by repurposing an old plastic storage container. By drilling a few small holes in the lid, you can control the level of humidity and ensure that your pottery remains perfectly damp.
4. Damp boxes can be a great help during the process of reclaiming clay. When clay has become too dry and hard to work with, placing it in a damp box for a couple of days can rehydrate and soften it, making it easier to reuse for future projects.
5. In addition to retaining moisture, using a damp box can create a more comfortable atmosphere for your pottery studio or workspace. As the water evaporates from the damp box, it adds humidity to the air, which can help prevent clay from drying too quickly and minimize the risk of cracks and warping.

Materials And Tools Needed
Before we start making a damp box, let’s gather all the necessary materials and tools. Here is what you will need:
- A plastic storage box (large enough to hold your pottery without damaging it)
- Plaster (such as plaster of Paris)
- Vaseline (or a release agent)
- Buckets (for measuring and mixing plaster)
- A pouring jug (to mix the plaster)
- Thin rubber gloves (for protection)
- A pottery rasp (to file edges of the plaster slab)
- A scrubbing pad (to eliminate bumps and lumps)
- A respirator mask (to protect against plaster dust)
- Rubbing alcohol (optional, for bursting bubbles)
It is important to collect all these materials before proceeding with the next steps.
Steps For Preparing And Mixing The Plaster
Once you have gathered all the necessary materials, it’s time to prepare and mix the plaster for your damp box. Follow these steps carefully:
-
Prepare the box: Find a suitable plastic container that is large enough to accommodate your pottery pieces without damaging them. Apply a thin layer of Vaseline to the inside of the box to prevent sticking.
-
Measure the water: Determine the appropriate amount of water needed for the plaster mixture. It’s recommended to use tepid water instead of warm water as it ensures a smoother consistency.
-
Mix the plaster: In a bucket, gradually sprinkle the plaster into the water. Allow the plaster to dissolve slowly, ensuring it does not clump together. Avoid using a drill and mixing bit as this can introduce air bubbles into the mixture.
-
Stir until the desired consistency: Use a pouring jug or a mixing spatula to stir the mixture until it has the consistency of double cream. The plaster should not be too thick or too thin. If you feel any lumps in the mixture, you can use thin latex gloves to remove them.
-
Pour the plaster into the box: Pour the plaster mixture into the prepared plastic box, making sure to pour it into a corner to reduce the amount of air dragged into the mixture. Tap the side of the container gently to help any bubbles rise to the surface.
-
Remove bubbles: To eliminate any remaining bubbles, you can use a technique called ‘shuggling.’ This involves gently shaking or vibrating the box to encourage the bubbles to rise. Alternatively, you can spray the surface of the plaster with alcohol, which helps burst any bubbles that come to the surface. Ethanol can be used as a substitute for whiskey when spritzing the plaster.
-
Allow the plaster to harden: Leave the container undisturbed until the plaster hardens. The drying time can vary, but it can take as little as half an hour or overnight, depending on the type of plaster used. Make sure to follow the instructions on the plaster packaging for the specific drying time.
-
Finishing touches: Once the plaster has hardened, you have two options for finishing touches. You can either rub down the surface of the slab using a scrubbing pad to eliminate any bumps or lumps or tap the container to slide out the plaster slab. Applying Vaseline to the container earlier facilitates easy removal of the plaster slab. You can use a pottery rasp to file the edges of the slab and remove any sharp bits of plaster.
Using The Damp Box For Storing Clay
Now that you have successfully created your damp box, it is time to put it to use. To store clay in the box and slow down the drying process, follow these steps:
- Prepare the plaster: Pour a small amount of water onto the plaster slab to make it damp. Be careful not to flood the plaster, as excess water can hinder the drying process.
- Soak up excess water: Use a sponge to soak up any excess water from the surface of the plaster.
- Place greenware on the plaster: Carefully place your pottery pieces, also known as greenware, onto the damp plaster, ensuring they are evenly spaced and not touching each other.
- Seal the box: Close the lid of the box tightly to create an airtight seal. This is important to maintain the desired humidity level inside the damp box.
- Check moisture levels regularly: It is recommended to check the moisture levels in the plaster periodically. If the plaster becomes too dry, you can add small amounts of water to maintain the desired dampness.
-
Adjust plaster thickness: The thickness of the plaster slab can affect the drying process. If you find that your pottery is drying too quickly, you can increase the thickness of the plaster to slow down the drying time. On the other hand, if your pottery is not drying at all, you may need to decrease the thickness of the plaster.
-
Make sure to pour water onto the plaster slab to make it damp, without flooding it.
- Soak up any excess water from the surface of the plaster using a sponge.
- Place your pottery pieces, known as greenware, on the damp plaster, ensuring they are evenly spaced and not touching each other.
- Create an airtight seal by closing the lid of the box tightly to maintain the desired humidity level.

Frequently Asked Questions
How do you make a damp box for pottery without plaster?
An alternative method to create a damp box for pottery without plaster is by using a sealable container and a damp cloth. Place your pottery inside the container and wet the cloth with water. Squeeze out any excess moisture and lay the damp cloth over the pottery, ensuring that it covers the entire surface. Seal the container tightly to create a humid environment that will slow down the drying process and preserve the quality of your pottery.
Another option is to use a damp sponge instead of a cloth. Wet the sponge, squeeze out the excess water, and place it next to or on top of the pottery inside the container. Similar to the damp cloth method, the sponge will release moisture into the air, creating a humid environment within the box. Remember to check the moisture levels regularly and re-wet the cloth or sponge as needed to maintain the desired level of humidity.
How do you make a damp cupboard for pottery?
To create a moist cabinet for pottery, begin by pouring a layer of around 1-2 inches of plaster into a plastic container. Once the plaster has solidified, smooth out any uneven surfaces or loose debris. Subsequently, hydrate the plaster by pouring water onto it, ensuring it becomes damp. Finally, carefully position your pottery on the moistened plaster and securely seal the lid of the enclosed container.
What is a damp box for clay?
A damp box for clay is a specialized storage container designed to maintain a consistent level of moisture for the clay. It is an essential tool for potters who need extended periods of workability with their clay. The damp box stores the moisture inside, creating an optimal environment for the clay to remain damp for long periods, allowing potters to work on their piece over an extended period, ensuring the clay doesn’t dry out or become unworkable. The controlled moisture level inside the damp box enables potters to shape and mold the clay with ease, providing flexibility and convenience in the creative process.
How is damp made?
Damp is created through a process known as condensation. This occurs when warm and moist air comes into contact with a cold surface or wall inside a building. In bad weather conditions, such as heavy rain or high humidity, damp can form more rapidly. Furthermore, if there are any existing issues with the exterior of the building, such as leaking roofs or damaged walls, it can exacerbate the problem and contribute to the formation of damp.
