|---|---|
| Description | खनिज वर्णक - Khanija Varnaka (Mineral Pigments) are inorganic colorants sourced from the earth, extensively used in Indic heritage architecture and art. These *prakritik varnak* (प्राकृतिक वर्णक) or *bhoovarnak* (भूवर्णक) [1] find application in wall paintings, frescoes, and decorative finishes. Common examples include *geru* (red ochre, Fe2O3), *ramraj* (yellow ochre, FeO(OH)·nH2O), and *neel* (indigo, C16H10N2O2, historically mineral-associated). Particle size typically ranges from 1-10 μm, influencing opacity. Refractive index and chemical stability vary based on mineral composition [2]. Sourced from quarries and mines across the Indian subcontinent, these pigments were vital during the Maurya, Rajput, and Mughal dynasties [3]. Durability depends on lightfastness and resistance to environmental factors. Conservation efforts address pigment degradation due to moisture, salt efflorescence, and biological growth. Traditional lime plasters and mortars (*chuna*) were often colored using these pigments. Restoration requires careful analysis and matching of original *khanija rang* (खनिज रंग) [4]. |
