Voiceover: The technique of cameo glass begins by layering different colors of glass and then inflating and shaping them together to form a vessel. When cool, decorative designs are carved into the outer layer. First, molten blue glass is inflated at the end of a blowpipe and stretched to form a tube. The tube is lowered into a pot of molten white glass. The white glass re-softens the blue glass. The two layers are reheated. The vessel's body is shaped and the bottom flattened. A pontil is attached and the vessel is broken free of the blowpipe. The mouth is reheated and then shaped to create the rim. Once cool, a cutting wheel removes excess white glass that overlays the blue. A design is laid out to guide the carving of the white glass. Smaller wheels are used to create the finer decoration. Liquid abrasive is dripped onto the wheel to help cut away the glass. Finally, a sharp tool is used to create the smallest details.
