Copper Kalasha

4.5/5(Based on 6 heritage sites)
Descriptionताम्र कलश (Tāmra Kalasha), or copper vessels, are integral to Indic heritage architecture, particularly in temples, serving as finials and auspicious symbols [1]. Predominantly composed of copper (Cu), these *kalashas* exhibit a density of 8.96 g/cm³ and a melting point of 1085°C. The high corrosion resistance of copper ensures longevity, crucial for structures exposed to diverse climates. Sourced from copper mines across the Indian subcontinent, the metal was processed using traditional methods like smelting and hammering, techniques documented since the Maurya and Gupta periods. The Chola and Vijayanagara dynasties extensively employed *tāmra* (copper) in temple construction. Conservation efforts address corrosion and structural fatigue, employing techniques like electrochemical cleaning and protective coatings to preserve these heritage artifacts. The *kalashas* also function as *ghata* (pots) for water storage in some applications. Their excellent thermal (401 W/m·K) and electrical (5.96 x 10⁷ S/m) conductivity are secondary considerations compared to their symbolic and aesthetic value.
