What is the maximum heat air dry clay can withstand?

Air dry clay typically can withstand temperatures up to around 200°F (93°C) before it begins to degrade or lose its structural integrity. Unlike kiln-fired clays, which can endure much higher temperatures, air dry clay is not designed for firing and will crack or warp when exposed to heat. It's best suited for decorative projects rather than functional items exposed to high temperatures. For items meant to withstand heat, consider using stoneware or porcelain instead.
