Sticklac is first crushed and sieved to remove certain impurities. It is then washed in large vats or barriers to remove insect bodies and a portion of the colouring matter. Washing is repeated until the dye and most of the impurities are removed. The Sticklac thus cleaned is spread on large clean open air floor to dry. After drying it is winnowed and sieved to get the commercial variety of Seedlac. It contains around 3-5% impurity. Seedlac as mostly used for conversion into Bleached Lac and different types of Shellac. U.S.A., Germany, U.K. and Japan are the main buyers of Indian Seedlac.
