Question 1

What is नारियल का खोल (Coconut Shell)?

Accepted Answer

Nāriyal Khol (नारियल खोल), or coconut shell, is a lignocellulosic agricultural byproduct [1] traditionally employed in Indic heritage architecture, particularly in coastal regions like Kerala and Tamil Nadu. Its chemical composition primarily consists of cellulose, lignin, and hemicellulose. Physical properties include a density of approximately 1.2 g/cm³ and a tensile strength ranging from 20-30 MPa. Historically, Nāriyal Khol served as a roofing material, a filler in mortar mixes (enhancing workability and reducing cracking), and a fuel source. In Sanskrit, it may be referred to as *Shriphala Kavacha* (श्रीफल कवच).

Traditional processing involved drying and sometimes charring the shells. Durability is affected by moisture content and fungal attack, necessitating conservation strategies like surface treatments with natural oils. In South Indian architecture, examples exist where coconut shell was integrated into partition walls and decorative elements. Restoration efforts at heritage sites require careful consideration of compatible materials and traditional techniques to maintain structural integrity and aesthetic value. The material's low thermal conductivity contributed to cooler interior spaces.
