Thewa Art — Pratapgarh's GI-Tagged Gold on Glass

The story

Thewa is that rarest of things: a jewellery technique invented in one town and still held, generations later, largely by one family. In Pratapgarh, in southern Rajasthan, the Soni family of goldsmiths developed a way of fusing intricately worked sheet gold onto coloured glass — a secret they have guarded for over 250 years, passing it from father to son. The name comes from the local word for 'setting', and what is set is extraordinary: a sheet of 23-carat gold, pierced and worked into miniature scenes — Krishna among the gopis, royal hunts, processions, birds and flowering vines — bonded to glass of deep green, red or blue so the metalwork appears to float on colour, lit from within. Thewa pieces travelled from Pratapgarh to princely courts and, in the colonial era, to European exhibitions, where the glowing plaques were mounted as brooches, boxes and jewellery. Members of the family have received national honours for the craft, and Thewa Art Work now carries a Geographical Indication tag, formally tying the technique to Pratapgarh. It remains slow, small-scale and stubbornly hand-made — which is precisely its value.

How it is made

A thewa plaque begins as a sheet of 23-carat gold, thin enough to work like foil but strong enough to hold detail. On this sheet the craftsman draws and pierces the design — figures, foliage, animals — using fine tools, creating delicate openwork with the density of lace. Separately, coloured glass is prepared and softened with heat. The worked gold sheet is then fused onto the molten glass surface, so metal and glass bond permanently; timing and temperature are the family's closely held secret, since too much heat destroys the gold work and too little fails the bond. The fused plaque, glowing like a miniature stained-glass window, is finally framed in silver or gold as a pendant, box lid or piece of jewellery.

Buying guide

Hold a piece up to light: genuine thewa glows, with the gold openwork sharply defined against luminous glass, and fine irregularities that betray the hand. Printed or stamped imitations look flat and mechanically even. Ask whether the gold is worked 23-carat sheet fused to the glass, and buy from sellers who can trace the piece to Pratapgarh. Small pendants typically start around ₹3,000; elaborate necklaces, boxes and framed plaques can reach ₹1,50,000.

Care

Treat thewa as you would fine glass. Store each piece separately in a soft pouch or box, away from anything that could knock or scratch the plaque. Keep it clear of perfume, hairspray and water, and wipe only with a soft dry cloth. Never use ultrasonic cleaners. If the frame loosens, have it repaired by a jeweller familiar with glass-set work.
