Lost wax casting involves making a wax replica of what you want your final object to be. The wax is placed in plaster and then the plaster is heated, which melts all the wax out, leaving a void in the shape of your finished item. When molten metal is poured into the mold, it takes its final shape and cools, leaving you with a metal replica of the wax carving. Jewelers use this to make rings, so I decided to give it a try. Actually, I made an Instructable on this endeavor, and the Instructable got featured (yay!), so check it out! I am also happy to say that the ring turned out absolutely stunningly!
