- Abstract
India is the goldmine of handicrafts. 'Dhokra' or 'Dokra' is a traditional metal casting art. It has enormous respect in both national and international markets. Dhokra is always considered art, whereas it is a technologically sound casting method. In the foundry world, it is famous as the 'investment casting process', 'near net shape casting processes', or 'lost wax casting process. The technical name of Dhokra is "wax-based investment casting in hot clay mold". Few tribal communities of eastern India (West Bengal, Chhattisgarh, Orissa, and Jharkhand) practice this technique. This 5000-year-old technology needs some development because only love and emotion are not enough to survive this technique. A planned technical analysis in light of modern engineering techniques is required to improve the quality and degree of excellence. Then only casting defects can be eradicated, and yielding and production costs can be minimized.
