Apparatus for ornamenting glass articles by abrasive blasting techniques comprises an article holding and masking arrangement useful for the mass production of ornamented glass tumblers of high quality. The glass tumblers are clamped within the article holder which includes mounting members for supporting the interior and exterior surfaces of the tumbler. Clamping pressure is applied to the exterior surface of the tumbler so that a mask can be applied with considerable force to an opposite portion of the exterior surface. The construction is such that during the process there is little or no relative displacement between the tumbler and the article holder. Consequently, after a first design has been blasted into the glass, a second mask can be applied to the article in accurate registry with the design formed through the first mask.
