Polymer clays are often used to make figures and other sctlpus (from simple and whimsical ones to quite realistic and/or elegant ones, etc). But the 3 lines from the Polyform company called original Sculpey (boxed), SuperSculpey (flesh-boxed), and Sculpey III (colors, pkgs) are more brittle after curing in any thin or projecting areas than the other brands/lines of polymer clay. They can still be used (especially SuperSculpey) if that’s kept in mind (and perhaps with wire or other armatures underneath) and in fact often are used, especially by those who simply want to paint over their clay sctlpus rather than using colored clays. The longer polymer clays are cured, the stronger they’ll be though no matter which brand so baking SS a long time will make it less brittle (though also darken it).The stronger polymer clays available in the U.S. are brands/lines like Premo, Kato PolyClay, FimoClassic, Cernit, SuperSculpey-Firm, and to a lesser degree FimoSoft. Those clays will have surfaces that are a little less hard than the more brittle ones, but that gives strength if those are stressed when thin, they’ll simply bend rather than snapping.(Lots of info on brands, baking, figures, etc, at my site glassattic.com, if anyone is interested.)
