Question 1

What is ताम्र कलश (Copper Kalash)?

Accepted Answer

ताम्र कलश (Tāmra Kalash), or Copper Kalash, is a significant element in Indic heritage architecture, particularly atop *shikharas* [1]. Fabricated from copper (ताम्र), its selection stems from copper's inherent properties: high electrical conductivity (5.96 x 10⁷ S/m) for lightning protection, thermal conductivity (401 W/m·K), and corrosion resistance [2]. Density is approximately 8960 kg/m³, with a melting point of 1085°C. Historically, copper was sourced from mines across the Indian subcontinent. Traditional fabrication involved smelting and hammering techniques. The Mauryan and Gupta periods saw extensive use of copper in various artifacts. Conservation requires careful cleaning to remove verdigris without damaging the underlying metal. Electrochemical treatments can mitigate further corrosion. The *kalash* (कलश) serves both a structural and symbolic role. Restoration often involves replacing damaged sections with copper of similar composition to maintain material integrity. The *Tāmra Kalash* is a testament to ancient metallurgical skills [3].
