Investment casting process reduces porosity and provides precise replicas. Sand casting, which is used by the masses results in trapped gases and other impurities resulting in an uneven product. People generally use sand casting as it is cheaper and fester but they do so at the cost of quality, which is where F&H does not compromise. Master makers and chasers use pendant motors, imported emery papers (German), and silicon carbide or diamond burrs from England to chisel out the fineness. There are 40 different kinds of tools to give the required shapes and dips in the silver pieces. After the first polish, the pieces go for hand chasing because some minute detail tend to get lost in the first polish. Final polish follows soldering which is when the silver gets its real elegance.
