While the operation just described has thus far proved success-ful, yet there is a possibility of the porcelain being broken from theplatinum pins which hold it to the gold plate. To avoid such anaccident, a groove should be cut on each side, and along the cuttingedge of the porcelain (Fig. 503, b), that gold-foil may be impactedinto it, after a heavy backing of gold plate and the wire have beenfixed in place and soldered. When the groove has been cut in the 556 MECHANICAL DENTISTRY. porcelain with a fine-edged corundum disc, one with an edge of thediameter of the gold wire selected for the case should be used tomake a gr
