Recommended time and temperature values may vary depending on the type of polymer clay used. Typically, temperatures range from 230°F to 266°F (110°C to 130°C), and cooking times range from 15 to 45 minutes. It is important to follow the specific recommendations of the manufacturer of the clay you are using, as each brand may have different requirements. It is important to take into account the thickness of the piece and the precise temperature of our oven. Usually, the cooking time is usually 30 minutes. However, if we exceed the cooking time, the piece may darken or lose color. In case you have mixed brands or types of clay, it is advisable to use the longest cooking time among all the brands.
