Nanakshahi Brick

Descriptionनानकशाही ईंट (Nanakshahi Īnt), also known as सिख ईंट (Sikh Īnt), are terracotta bricks prevalent during the Sikh Empire (18th-19th centuries CE) in the Punjab region. These ceramic materials, derived from alluvial clay deposits – *mrittika* (मृतिका) in Sanskrit – underwent firing processes at temperatures typically between 950-1050°C. Their composition primarily consists of silica, alumina, iron oxide, and lime. Physical properties include a compressive strength of 4-10 MPa, water absorption of 15-22%, porosity of 20-25%, and a density of 1600-1800 kg/m³. Nanakshahi bricks, often larger than लखौरी ईंट (Lakhauri Īnt), were employed in wall construction, fortifications, paving, vaulting, and decorative facades. Traditional brick hammers [1], *ghana* (घन), were used in their production. Conservation efforts at heritage sites like forts and *gurudwaras* (गुरुद्वारा) require careful matching of brick size, color, and composition. Durability is affected by weathering and salt efflorescence, necessitating appropriate restoration techniques. Understanding the *dravya* (द्रव्य) or substance, and its *guna* (गुण) or properties, is crucial for preservation.
