6-1/2" "Vintner" on Blue Burmese Sand Carved Cameo Vase. Cameo carving is a a painstaking process. After the glass has been annealed, a special mask is taped to the surface of the glass. Using an advanced ?vignetting? technique, each piece is carefully sandcarved, by hand, using aluminum oxide crystal under pressure to take away some of the surface. Great individual skill and experience are needed to control this operation, as many distinct stages of successive cameo carving are required to create the remarkable depth and the intricate details.
