| Description | लौहयुक्त पत्थर - *Lauhayukta Patthar* (Ferruginous Stone), also known as *Lauhamay Patthar* (Iron-rich Stone), encompasses iron-bearing sedimentary and metamorphic rocks prevalent across Jharkhand, Chhattisgarh, and Odisha. Its iron content (10-50%) contributes to its characteristic reddish-brown hue. Density ranges from 2.8-3.5 g/cm³, with compressive strength between 40-90 MPa. Traditional *shilpis* (artisans) sourced this *shila* (stone) from regional quarries and mines for constructing *adhisthana* (foundations) and load-bearing walls [2]. Ancient and medieval Indic architecture extensively utilized *Lauhayukta Patthar*. Its durability made it suitable for *murti* (sculptural) elements and road construction. Variable porosity necessitates careful conservation strategies. Restoration involves addressing weathering and iron oxide leaching. Traditional lime mortars (*chuna*) were often used in conjunction with this stone [3]. Understanding the geological origin and mineralogical composition is crucial for effective preservation of heritage structures built with *Lauhayukta Patthar* [1]. *Ayaskiya Patthar* is another synonym. |
