As part of my fieldwork and classroom teaching, I have used all kinds of casting materials, including plasters, clays, and gels. Your clay is the best material I’ve found to work with! It is soft, but not too soft. It isn’t oily and doesn’t dry out. After it is baked, it doesn’t crack or shrink like other clay products I have used. It is so easy to use, anyone can do it! Thank you for providing such a superior, yet affordable, product!
