Shellac Flakes - HAND MADE
IndoLACCA HM LEMON 1
About
The term “Shellac” describes the refined Lac resin in the form of flakes.
The Hand Made Shellac is obtained by the process of manual hot-filtration, whereas the Seedlac of a suitable grade is used as the raw material.
The Seedlac is packed into a long, narrow sausage-shaped canvas bag held in place by two workers in front of an open charcoal fire of the Dutch Oven type. The Seedlac inside melts and the workers twist the bag in opposite direction so that the molten Lac is forced out through the walls of the bag.
The molten Lac is then spread out on a porcelain cylindrical jar containing boiling water into a sheet approx. 2.5 feet long and 0.25 inch thick. Now holding the lower corners of the sheet by means of his toes and the upper ones with his hands and grasping the centre of the upper edge with his teeth, the worker very skillfully and gradually stretches the sheet into a large thin sheet of the desired size. This operation is carried out in front of charcoal fire to keep the resin plastic.
The Sheet is then broken into small pieces to form Shellac flakes which are aerated in a well ventilated room before packing.
Owing to it’s versatile characteristics of corrosive resistance, moisture resistance, electrical insulation and thermoplastics, Shellac has find it’s wide application across various industries from food industry, pharmaceuticals, electrical, cosmetics etc.
