"At first the available colors are ground on a stone slab (by rubbing or grounding) to bring them in a powder form. Some artists use mortar and pestle of a very hard quality stone. Then that color is dissolved in water along with some gum and then filtered. The filtration process is continued till the color becomes totally earth or sand free. Thereafter water is removed and the color is dried and kept in form of balls. When required, the desired color along with some dry gum is dissolved slowly in water with the help of finger or thumb.'
