Lac production is found in Assam and other parts of North-East India, Bangladesh, Myanmar, Thailand, Laos, Vietnam and parts of China

The raw sticklac is crushed into small grains, sieved, washed in mild alkaline water and dried, removing impurities to produce seedlac. 

Traditionally, seedlac is processed by hand. It is packed into a long, narrow, cloth bag, heated by a bhatta (charcoal fire), and forced out through the pores of the bag; leaving behind impurities. The filtered mass is drawn into sheets of approximately 0.5cm thickness by skilled workmen. The resulting product is known as button lac or flaked shellac. The prefix button refers to its pellet shape. The flake shellac is then used to make the varieties of grades of shellac that forms the basis for coating and glazes.

Machine processed shellac is currently made either by melting the sticklac on steam-heated grids and squeezing the soft molten lac through a filter by means of hydraulic pressure; or by dissolving it in a solvent and filtering the solution before feeding it through evaporators in order to concentrate it. Both of these methods end with the shellac product being rolled into sheets mechanically; ready to be flaked. 

We improve upon the traditional processing methods by tripling the validated methods of bioburden control.
