|---|---|
| Description | वज्रलेप (Vajralepa, Diamond Plaster) is a composite material employed extensively in Indic heritage architecture, particularly during the Chola and Vijayanagara periods. Its composition typically includes चूना (Chunā, Lime Mortar) sourced from limestone quarries across the Deccan Plateau, सुरखी (Surkhi, Brick Dust) derived from fired clay bricks, and aggregates like बालू (Bālū, Sand) [1]. The addition of plant extracts (e.g., gum arabic) and resins enhances its binding properties and water resistance. The term वज्र (Vajra) signifies diamond or strength, reflecting the plaster's exceptional durability. Traditional processing methods involved meticulous grinding and mixing of ingredients, often using specialized plastering tools [1]. Vajralepa exhibits high compressive strength, low water permeability, and good adhesion to masonry substrates. Conservation efforts at heritage sites necessitate careful analysis of the original composition and the use of compatible repair materials to maintain its integrity. The geological and biological origins of its components contribute to its unique properties. |
