ABSTRACT:
A method of heat polishing pattern cut glassware by subjecting the surface hereof to high heat resides in that the heat polishing is carried out by a beam of concentrated heat flow with sequential movement thereof along the entire surface of the glassware being polished, the selectable effective width of the concentrated heat flow being substantially less than the circumference of the ware being polished, each element of the cut pattern being exposed to equal heat stress.
