Sculpey is one of the oldest names in polymer clay, going back to the late 1960s, and it is made in the United States.

A bakeable adhesive for joining clay to clay — raw to raw, raw to baked, or baked to baked. It is the answer to the awkward repair: adding a new piece onto something already fired, or rejoining a part that has snapped.

It also bonds clay to porous materials such as wood and paper, which is where a glue earns its place over liquid clay.

Using it: parts join under light pressure, so fine details and thin shapes do not distort while you position them. It must be baked to cure.
