Today, more and more artists that create in the clay medium use epoxy clays as opposed to traditional wet clays because of their self-hardening feature. Epoxy clays require no firing and will harden in approximately three hours which makes them an attractive alternative for artists. Art Place carries Magic Sculpt and Apoxie Sculpt you can use to make various pieces of art from jewelry to figurines. You can also find Fixit Sculpt versatile enough to repair and patch holes, cracks, and leaks for most household items, plumbing repairs, and other works of art.
