Molds, Jelly and Ice Cream

molds, jelly and ice cream, shape jellies (gelled juices) and ice creams for dramatic presentation. Early European and American molds were produced largely from pewter, a metal that transmits heat fairly slowly and allows for a brief immersion in warm water or for standing at room temperature, a process that melts a very thin layer of the jelly or ice cream and permits it to be unmolded without losing its shape or the decorative pattern from the mold. Other materials used in the manufacture of molds have included red-ware, yellow-ware, ironstone, copper, stamped tin, and steel. Today, molds are often made of flexible silicone.
