Use

Drying / Storing
Store unfinished pieces in an airtight bag wrapped with a damp cloth. Keep unused clay in an airtight container. When drying, rotate pieces so all sides get even exposure to the air. Dry times depend on thickness, size, and surrounding environmental conditions. Typically pieces are ready to decorate in 24 hours and fully cured in 48 to 72 hours.
Finishing
Sandtastik® Modeling Clay accepts virtually any type of finish.
Firing
Sandtastik® Modeling Clay is primarily composed of all natural clay so if you choose it can also be kiln fired. Low fire between cone 06 (1796° F) and cone 04 (1868° F). Fire in a well-ventilated area as Plus clay’s organic matter will start to burn out at 266 F and will emit an odor.
NOTE: After firing the black Modeling Clay the color becomes red.
Caution
The addition of water to the Sandtastik® Modeling Clay results in greater shrinkage. This can lead to cracking and deformations during the drying process. If working with an armature or over a rigid form, completely cover it with a layer of paper before applying the Modeling Clay. This will help reduce the chance of cracking during the drying process. Sandtastik® Modeling Clay is not food grade material.
