Lac
Explanation
Forest products are classified into major forest produce (timber) and minor forest produce (non-timber). Sealing wax is a material primarily derived from natural resins obtained as minor forest produce.
Detailed Analysis:
- Lac: It is a natural resin secreted by the lac insect (Kerria lacca), which inhabits host trees such as Palas, Kusum, and Ber. The resin is processed to produce shellac. Shellac is the primary raw material used in the manufacture of sealing wax due to its low melting point and adhesive properties. India is one of the largest producers of lac in the world.
- Gum Arabic: This is a hardened sap obtained from the acacia tree. It is primarily used as a stabilizer in the food industry, in printing, and in the production of adhesives and paints, but not for sealing wax.
- Catechu (Katha): This is an extract obtained from the heartwood of Acacia catechu. It is widely used as an ingredient in paan (betel leaf preparation) and for tanning leather.
- Plywood: This is a manufactured wood panel made from thin sheets of wood veneer. It is a structural material and not a raw material for wax production.
Key Takeaway:
Lac is a natural resin of insect origin used to produce shellac, which serves as the base material for sealing wax, varnishes, and polishes.
