Quickcure clay does not require mixing or conditioning - it’s ready to use right out of the package, and it does not need to be stored in an airtight container or have a limited shelf life- quickcure clay will not dry out or harden if left out uncured. This clay formulation is ideal for jewelry making and for sculpting. It adheres to wood, paper and many plastics and it bonds to already cured clay allowing objects to be prepared in steps. Quickcure clay has a strength similar to epoxy clay, it can support 6,000 lbs. Per square inch. It is stronger than other polymer clays and air dry clays on the market, and once it is cured it is compatible with tin-cured and rtv silicones. Available in natural and black color.
