What Is Foaming Clay?
What is Foaming Clay?
Foaming clay, also known as foam clay or air-dry clay, is a lightweight modeling compound made primarily from polyvinyl alcohol, glue, and foaming agents. It has a soft, rubbery texture and can be easily shaped into creative designs.
Foaming clay was first developed in the 1990s as an alternative to traditional clays like polymer or oil-based clays. Unlike regular clay that hardens as it air dries, foaming clay expands into a foam-like consistency when exposed to air. This gives it a uniquely lightweight and fibrous texture.
The key differences between foaming clay and regular clay are that foaming clay is:
- Extremely lightweight – Foaming clay is made with foaming agents so when exposed to air, it rises like a souffle into a soft, airy material.
- Quick-drying – Foaming clay fully dries and hardens in 24-48 hours as it reacts with oxygen, while regular clay can take days or weeks to fully cure.
- Easy to shape – The foam structure gives foaming clay a soft, pliable texture that is easy to squeeze, sculpt and form organic or abstract shapes.
- Non-toxic – Made without oils, firing or glazes, foaming clay is non-toxic and safe for kids to use.
These unique properties make foaming clay a versatile material for free-form arts and crafts projects.
How Foaming Clay Is Made
The main ingredients in foaming clay are shaving cream, glue, and baking soda. Typically, foaming clay recipes call for combining 2-3 cups of foaming shaving cream with 2/3 – 1 cup of white glue like Elmer’s. To this base mixture, 1-1.5 tablespoons of baking soda is added as a foaming agent. Some recipes also include a small amount of saline solution or eye drops to adjust the consistency. The ingredients are mixed together thoroughly until a smooth, clay-like dough is formed.
While basic foaming clay can be made at home using this simple recipe, there are also commercial modeling clays sold as “foam clay” or “foaming clay”. These often contain additional ingredients beyond the basics to create specialized properties. For example, Pixiss Foam Clay uses a proprietary blend of polymers for increased strength and smoothness. Brands like Bohs add plasticizers for enhanced elasticity and workability.
Some types of foaming clay are pre-colored, but most basic homemade or commercial varieties accept acrylic paints readily. The open cellular foam structure allows paint to penetrate and cover easily. Manufacturers may also add pigments and colorants to produce foaming clays in a rainbow of vibrant hues straight from the package.
Properties of Foaming Clay
Foaming clay has a lightweight, soft texture that makes it very easy to shape and mold into any form. Unlike natural clays that can dry out and crack if handled too much, foaming clay maintains its softness even after repeated handling, allowing for continued reshaping. The foam-like texture gives it a smooth, malleable feel that lends itself well to sculpting and modeling intricate details.
One of the most useful properties of foaming clay is that once left to dry, either in the air or baked at low heat in the oven, it hardens while retaining its molded shape. The hardened clay can be painted, glittered, and decorated as desired. Yet if the clay needs to be reshaped later, simply wetting it with water temporarily returns it to a pliable state.
Overall, the dynamic properties of foaming clay, from its lightweight and moldable texture to its hardening capabilities, make it an extremely versatile material for arts and crafts of all kinds.

Tips for Working with Foaming Clay
Foaming clay can dry out quickly, making it harder to shape. To keep the clay soft and pliable while you work:
- Store unused clay in an airtight container or plastic bag.
- Mist clay periodically with water from a spray bottle.
- Knead clay to warm it up before use.
You can create smooth or textured finishes. For smooth surfaces, use your fingers or acrylic rollers. For texture, imprint designs using household objects or clay tools before the clay fully dries.
Foaming clay must be baked to fully harden. Bake at 200°F for 30 minutes to set the shape. For painting, apply acrylic paints after baking. Seal painted pieces with varnish for protection.

Storing and Preserving Foaming Clay Creations
Proper storage is important for preserving foaming clay creations. Here are some tips:
Use airtight containers like plastic boxes or bags to store unused foaming clay. Make sure to squeeze out excess air and seal the container completely to prevent the clay from drying out. Some clays can be stored in the fridge for extra longevity, but check the packaging instructions.
For finished foaming clay pieces, seal them with a protective finish like varnish or glue to prevent damage. Avoid displaying them in areas with direct sunlight or moisture. Dusting regularly will also help maintain their appearance.
Consider covering the piece with a clear acrylic spray as a protective barrier. This seals the clay and provides a glossy finish. Let pieces fully cure before sealing.
For long-term storage, wrap cured pieces in acid-free tissue paper and place inside archival plastic bags. Store in a climate-controlled area out of sunlight. Check periodically for any damage or deterioration.
With proper sealing and storage methods, foaming clay creations can last for many years. Take steps to limit moisture, uv rays, dust, and other environmental factors that could degrade the clay over time.
Safety Considerations
Foaming clay is generally considered non-toxic, but there are some safety precautions to keep in mind when working with it:
Supervise young children when using foaming clay. Although the clay itself is non-toxic, small pieces could present a choking hazard if swallowed. Additionally, some foaming clay products contain borax as an ingredient, which can be toxic if ingested in large quantities.
Foaming clay can stain surfaces, clothing and skin. Use it in a contained area and have clean-up materials like soap and water readily available. Lay down a plastic tablecloth or work surface if needed.
Those with skin sensitivities or allergies should do a patch test before extended use. While rare, some people may experience skin irritation from prolonged contact with foaming clay. Discontinue use if any reaction occurs.
In summary, foaming clay is safe for most people when used properly, but small children should be monitored and basic precautions taken to avoid ingestion, messes or skin irritation.
