The light, transparent layer is highly resistant to scratches and provides final protection for the product. Shellac is a resinous substance secreted by the enamel shield louse, an insect accumulating on tree branches. It is primarily found in South and Southeast Asia, especially in India and Thailand, where it was once produced in large quantities, with an annual output of around 50,000 tons. Approximately 300,000 enamel shield lice are needed to harvest a kilogram of Shellac. For gilders, Shellac serves mainly as a protective coating and is restricted from being used in painting techniques.
