Partabgarh in South Rajasthan has a very special technique called theva in which extremely fine work in gold leaf is done on red, green and blue glass. The pattern is first painstakingly punched out on gold leaf embedded on lac. Coloured glass of the same measurement and encased in a frame is then heated and, while still hot, the gold film is slipped over the edge and pressed onto the surface of the glass. The article is reheated until a sort of fusion takes place between the two. Silver foil is placed beneath the glass to give the surface a uniform glow. From elaborate hunting scenes to intimate rasa lilas, intricate patterns are made on the surfaces of plates, caskets, panels and ornaments in this technique.
