CENTRIFUGAL OR LOST WAX CASTING JEWELRY CASTING BOOK

This may be an old and revised classic and the waxes are better today along with the mold making rubbers.
But the info has pretty much remained the same.
So you could cast tomorrow after reading it today.
It does cover all the areas, including white metal casting and gold refining.
These two subjects have been lacking in most of the latter books on this subject.
