Origin
:-
Shellac is mainly produced in India and Thailand. Smaller quantities come from China and Vietnam. The product is manufactured in a process known since the old times as melting filtration. Nowadays hiqh-quality, dewaxed and decoloured Shellac is
manufactured.
Components :-
Raw Shellac (sticklac) contains 60-80 % pure Shellac, 4-6 % Shellac Wax and impurities such as splinters of wood, dead insects and moisture. Seedlac is washed and purified Sticklac and consists, according to its quality, of 85-90 % pure Shellac, 5-8 % Shellac Wax and 2-5 % impurities.
