Cabochons are glass studs or pastilles of various shapes and sizes which were applied to the surface of the vase and adhered through heat. They could be used simply as to decorative motifs in their own right, frequently placed symmetrically around the vessel and neck, mid body or foot, or used as part of an overall design, and could be left as smooth bulges or carved. Transparent glass cabochons placed over metallic foil or colored silver would acquire the color beneath when viewed head on. Cabochons placed within the overall design were often carved as a flower’s corolla.
