Sorry, plasticines ( "modeling clays ") can't be dried out, though they will kind of firm up a bit over time (if you try to heat them, they'll just melt due to the added wax they contain). They're created on purpose so they won't harden. The best you could do would be to put them up somewhere so they can't be disturbed or put a glass dome/ etc over them. If you really wanted to, you could create a mold with pourable latex or even 2-part silicone putty if the clay isn't too thin anywhere, then use another clay or material to cast in that mold to duplicate what you already have. Next time you want a permanent item, use an air-dry clay** or a polymer clay***. Air-dry clays will dry on their own in about 24 hrs, but polymer clays will not harden until they're baked (low temp, short time, home oven). Polymer clays are also oil-based and feel more like plasticines than many air-dry clays but air-dry clays will also shrink a bit and must be sealed after drying. **homemade like bread clay or salt dough clay, which are both good: google.com/ search?hl= en &q= how+ to+ make+ bread+ clay google.com/ search?hl= en &q= how+ to+ make+ salt+ dough ....or store-bought like Creative Paperclay or Makins, or for somewhat lesser-quality/ smoothness like Crayola's Air Dry clay or Model Magic, or even Celluclay (needs water added and may end up not smooth but can be sanded) ***Premo, Kato Polyclay, FimoClassic, Cernit... or FimoSoft... less strong in thin areas after baking would be Sculpey III, SuperSculpey (flesh), and original boxed Sculpey/ Polyform HTH, Diane B. |
