Manbhum Fine Bysacky

Manbhum Fine Bysacky Seedlac is a mid-tier seedlac grade, processed from Bysacky sticklac collected from the Manbhum region of India. This grade is distinguished by its moderate impurity level and relatively darker hue, making it suitable for applications where purity is important but not critical. The lac is thoroughly washed and sun-dried to remove insect bodies, dirt, and much of its natural dye content, yet retains a strong natural resin profile. It serves as a reliable raw material for manufacturing a wide range of shellac-based products, including bleached lac and various machine-made grades.
