Nathu ji Soni invented the process; the secrets of the craft that passed directly from father to son over the generations remains it in the family only, who call themselves ‘Raj-Sonis’. UNESCO, National & State Government, has awarded many of the members from this family. Some of the finest examples of this unique form of decorative art are in local museum collections in India as well as abroad including the Metropolitan Museum of art and the Victoria & Albert.
Like the rest of Rajasthan handicrafts, the glass works of Pratapgarh are unique in both design and usage. Besides beautiful and traditional items such as handicraft items, glass photo frames, trays, glass art ware, glass jewelry boxes, lamp shades, flower vases, crystal wine glasses, flasks, glass pots, antique crystal chandeliers, glass coasters, glass lamp shades and glass paintings, Pratapgarh is renowned for its Thewa work. Colored glass base, embossed with golden miniature artwork is the special attraction of the Thewa work. Floral patterns are etched on gold foil and superimposed on glass moulds and the glassware is cast in such moulds. Thewa pendants are famous pieces of jewelry and their blazing hues and exquisite patterns attract women across the world.
