DescriptionVeṇkalam (Bronze), a *kāṃsya* (कांस्य) alloy of copper and tin, features prominently in Indic heritage architecture, particularly in South India [1]. Its composition, typically 88% copper and 12% tin, yields a density of 7400-8900 kg/m³ and a melting point between 900-1050 °C. The alloy’s good to high corrosion resistance contributes to its durability. Traditional *dhātu karma* (धातु कर्म) processing methods, including lost-wax casting (*madhuchchhishtavidhana*), were employed by the Chola Dynasty for crafting icons and architectural details in temples like Brihadeeswarar. Bronze artifacts, sourced from *khani* (खनि) mines in regions like present-day Jharkhand and Rajasthan, exhibit tensile strengths ranging from 220-690 MPa. Conservation efforts address corrosion and structural fatigue in *mandira* (मंदिर) temple sculptures. Thermal conductivity ranges from 40-60 W/mK. The Vijayanagara Dynasty also utilized bronze extensively.
