What is the difference between raw material and a finished product?
Raw materials are the basic natural ingredients we start with (like cotton or clay), while finished products are the final items we actually use (like shirts or pots).
How is coir made in Kerala?
Coir is made by soaking coconut husks in water (retting), extracting the strong fibers, and then spinning them into ropes and mats.
Why do we need to bake clay pots in a kiln?
Baking removes moisture and hardens the clay, making the pots strong and durable for holding water and cooking.
