First, a coal fire is lit in a small bowl for the lac chips to be heated. The lac chips are stuck to the end of a wooden stick and held over the fire to melt to the required consistency. Natural coloured dyes are used to tint the lac. Sometimes, turmeric is used for the colour yellow, indigo powder for blue, and deep red cosmetic powder, locally known as kum kum, for orange and red. The process of preparing the resin needs dexterity, which comes from the transferred experience of generations of artisans practicing wood craft in Channapatna.
