A piece of thin, pure gold plate or mica is then adjusted oneach side of the crown (B, Fig. 397), the surfaces of which, if dryand slightly warm, will be held in position temporarily by pressingthem gently against the side of the wax. This is all now investedtogether (Fig. 398). The long ends of these side pieces, after being invested, holdthem in position, as the investment should be cut away so as toexpose the sides of the crown as shown at A, Fig. 398.
