Thank you Denise for the photo of your items!

Some really interesting things you can mold with Alley Goop: polymer clay, plaster, wax, resin, chocolate or other confectionaries! This mold compound is FDA approved for food. Melt chocolate or sugar pastries into the mold, put the mold in the freezer to harden the chocolate and then pop your chocolate item out of the mold to add to cakes and other confectionaries. Other places where it is used are crime labs, antique restoration, doll repair, veterinary clinics, bakeries....
