Shellac is scraped from the bark of the trees where the female lac bug, Kerria lacca (Order Hemiptera, Family Kerriidae), also known as Laccifer lacca, secretes it to form a tunnel-like tube as it traverses the branches of the tree.
Shellac-based primers are an effective sealant to control odours associated with fire damage. Shellac has traditionally been used as a dye for cotton and, especially, silk cloth in Thailand, particularly in the north-eastern region. It yields a range of warm colours from pale yellow through to dark orange-reds and dark ochre.
