|---|---|
| Description | कृष्ण शिला - Krishna Shilā (Black Stone), encompassing *Kala Pathar*, *Shyam Shila*, *Karungal*, *Nalla Raayi*, and *Kappu Kallu*, refers to dark-colored igneous rocks like basalt and gabbro utilized extensively in Indic heritage architecture [1]. Originating from quarries across Maharashtra, Karnataka, Andhra Pradesh, and Gujarat, these rocks exhibit high compressive strength (100-350 MPa) and density (2.7-3.3 g/cm³) [2]. Fine to medium grain size and low porosity (<1%) contribute to exceptional weathering and abrasion resistance. Satavahana, Chalukya, Rashtrakuta, Yadava, and Maratha dynasties employed Krishna Shila for foundation stones, paving, structural elements, and sculptures. Traditional processing involved quarrying and shaping using tools, including *stone burins* [1]. Its durability made it ideal for *Lingams* and temple construction. Conservation necessitates understanding its thermal expansion coefficient (5-10 x 10⁻⁶ /°C) and water absorption (<1%) to mitigate deterioration in heritage sites. |
