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 water-based gloss glaze for sealing and shining baked polymer clay. It dries to a hard, high-shine finish and is compatible with acrylic water-based products.

Applying it: thin coats, 30 minutes between them, then leave it 24 hours to cure fully before handling. If it has thickened, a couple of drops of water stirred in gently brings it back. The twist cap gives you flow control straight from the bottle.

Test it first. Sealers behave differently on different clay brands, so glaze a baked scrap of the clay you are actually using and leave it a few days before committing a finished piece.
