Is produced in two different ways- one is the heat process where the same principle as in the case of hand made shellac is applied and the second is solvent process where pure shellac is extracted from Seedlac by suitable solvents. Under heat process the separation of pure lac is achieved by melting Seedlac by steam heat and squeezing the soft molten lac through filter my means of hydraulic presses. The molten lac is then stretched by means of rollers into long continuous sheet which is broken into pleces to form the machine made Shellac under heat process. This shellac has an impurity content varying from 0.5 to about 1%. There are various grades under heat process machine made shellac. The most popular being TN, Lemon and Orange. These grades are exported to practically all lac consuming countries..
