Machine Made Shellac

Machine Made Shellac(Heat Process) :
Seedlac is melted onto steam-heated grids. The molten lac is forced by hydraulic pressure through a sieve or screen, either of cloth or fine mesh. The filtered shellac is collected and transferred to a steam-heated kettle, which then drops the molten liquid onto rollers. The molten lac is then stretched by means of rollers into long and continuous sheets which is broken into pieces to form the machine-made shellac under heat process. The Shellac obtained is kept in cool atmosphere for a day in order to improve its life. This shellac has an impurity content varying from 0.6 to about 1%. There are various grades of machine made shellac under the heat process mentioned above. The most popular being TN, Lemon and Orange. All the three grades are exported in bulk amounts in several countries.
