Cold Porcelain vs. Polymer Clay: What's the Difference?

Edited by Sumera Saeed || By Sara Rehman || Published on December 31, 2023
Cold porcelain is an air-dry clay known for its fine, porcelain-like finish, whereas polymer clay is a bake-to-harden modeling material used for crafting and art.

Key Differences

Cold porcelain is a homemade or commercially available air-dry clay, known for its smooth, porcelain-like texture. Polymer clay, a PVC-based modeling clay, requires baking in an oven to harden, offering a durable and versatile medium for artists and hobbyists.
