Lac is the scarlet resinous secretion of the insect Laccifer lacca.

Laccifer lacca belongs to the family of scale insects and mealy bugs Coccoidea a large family of plant sucking insects. Thousands of these tiny insects colonize branches of suitable host trees and secrete the resinous pigment. The coated branches of the host trees are then cut and harvested as sticklac.

The harvested sticklac is then crushed and sieved to remove impurities. The sieved material is then repeatedly washed to remove insect parts and other soluble material. The resulting product is known as seedlac.

Seedlac which still contains 3-5% impurities is then processed into shellac by heat treatment or solvent extraction.
