baking clay

Oven‑bake polymer clay stays soft and flexible until it is cured in the oven; baking hardens it into a firm, non‑tacky form. Uncured clay will not air‑dry, and any unused clay can be stored and reused later.

Follow the product directions: the listed guidance is 275 °F (130 °C) for 15 minutes per 1/4 in (6 mm) of thickness. Do not microwave polymer clay and avoid exceeding the recommended temperature or bake time.

Store polymer clay in a cool, dry place out of direct sunlight—ideally below 77 °F—and keep it in clay‑compatible containers or polypropylene (PP) bags to preserve freshness and workability.

Common formats shown include single 8‑ounce bars, one‑pound blocks, and sampler packs (for example, packs made up of thirty 1‑ounce bars).

Listings typically cite oven limits around 500–520 °F, and some items note they can go from the freezer into a 500 °F preheated oven. Always check the product’s specified maximum temperature before use.
