Ancient Roman, group of 3: Bronze cube and square shaped jewelry molds, used for making jewelry by the "lost wax" technique. This technique involves the following stages: two stone or terracotta molds were made with the form of the jewelry worked on them in reverse, in intaglio. Precisely half the piece was carved on each mold. Molten wax was poured into these molds, which was then replaced by molten metal. 200 AD (1 1/2" - 2"). http://sadighgalleryroman.moonfruit.com
