Virtually all metals and alloys, therefore, can be cast and this confers great versatility with respect to the processin

This coated medium is allowed to take-up the required form around a suitable heated pattern thus causing the resin to convert to a thermosetting condition such that, upon removal, it retains its shape without a distortion. This shape subsequently forms the

While within a few years additional patents were issued in both Germany and America, the development of the art was slow and erratic for over one hundred years. The first substantial growth in the process occurred in the casting of pipe after World War I. At a
