The Casting Process

Below is a series of photos showing the process to create a bronze goblet using the lost wax molding technique. Our sundials are cast in a similar manner except instead of a wax mold being made that melts away during the casting, a two sided impression is made into sand which creates the chamber for the molten brass to be poured. In both techniques the sand/clay is broken away after cooling and the mold cleaned and finished.
