About bronze
The Newari metalworkers of Patan (Lalitpur) are among the world's finest bronze casters, continuing a tradition that stretches back over 2,000 years. Their lost-wax (cire perdue) casting technique produces extraordinary Buddha statues, Hindu deities, and decorative figures that are sought after by temples, collectors, galleries, and interior designers worldwide. Each statue begins as a hand-sculpted wax model, is encased in clay, and fired to melt the wax and create a mold — hence 'lost wax.' Molten bronze or brass is poured into the mold, and after cooling, the clay is broken away to reveal the metal figure. Fine detailing, chasing, and gold or copper gilding are applied by hand.
How they are made
A master sculptor creates the original model in beeswax, building fine details layer by layer. The wax model is coated in multiple layers of fine clay and allowed to dry completely — this can take 1-2 weeks. The clay mold is fired in a kiln, melting out the wax and hardening the mold. Molten bronze (heated to approximately 1,100 degrees C) is poured into the cavity. After cooling, the clay mold is carefully broken away — each mold is destroyed in this process, making every piece unique. The rough casting is then filed, chased (detailed with fine engraving tools), and polished. For gold-gilded statues, a mercury-gold amalgam is applied and heated to bond pure gold to the surface — a technique called fire gilding that produces an unmatched luster.
