It probably is better to describe the casting as a “2 part sand mold”. “Lost wax” process is a one piece sand mold where the wax pattern is melted before the bronze is poured. Thus the term “Lost Wax”. These have no mold marks. In the 2 or 3 part mold, the pattern is physically removed before the mold is reassembled and the bronze poured. Where the mold parts come together, some bronze leaks between the parts leaving a ridge that must be removed.
