Common types include air-dry modeling clay (hardens without baking), reusable modeling compounds designed for repeated squishing and shaping, and light, stretchy airy doughs made for sensory play.
Air-dry clay can become dry to the touch within about 24 hours and is often allowed to fully air dry for up to 72 hours, depending on thickness and conditions.
Common ingredients include wheat, water, salt, and flour for many modeling compounds. Some products also advertise being free of common allergens such as gluten, egg, milk, peanuts, and soy.
Common inclusions are sculpting tools, rollers, cutters or cookie cutters, stamps, storage buckets or totes, plastic knives, and other shaping tools.
Net weights vary widely. Examples from available options include 96 grams and several ounce sizes such as 7.5 oz, 8 oz, 10 oz, 15 oz, 20 oz, 40 oz, and 60 oz.
Air-dry clay can be painted once dry and generally holds its shape well. Some users report that fine surface details or impressions may soften or be lost during drying, while others find finished pieces sturdy and crack-free.
