Seedlac is converted into Shellac either by traditional hand made process or comparatively modern machine made process. Hand made shellac is produced by properly blending Seedlac into a long narrow cloth bag and heating one end over a charcoal fire and the other end is attached to a windlass and is gradually twisted. The heat produced by the charcoal fire melts the lac which is forced out through the cloth by pressure. The molten lac is scraped out and drawn into sheets manually and left to dry. This process requires considerable manual skill and long experience.
