Golden Kusmi

Golden Kusmi Seedlac is a premium variety of seedlac that is known for its high purity, excellent clarity, and characteristic golden hue. This grade is derived from Sticklac, which has undergone a thorough washing, sieving, and drying process to remove insect residues, woody impurities, and a significant portion of natural coloring. The term “Kusmi” refers to the lac produced in specific regions of India, especially known for higher quality due to environmental and botanical factors. Golden Kusmi Seedlac is one of the finest grades and is highly sought after for its suitability in manufacturing high-grade bleached lac and shellac products. Its low insoluble content and attractive appearance make it a preferred choice for industries demanding high visual clarity and refined shellac derivatives.
