The filtering process of shellac in traditional handmade method needs charcoal as a fuel. In large scale processing system the filtering is through hydraulic press. The present technique uses house hold items viz. pressure cookers, hollow cylinder, one double burner gas oven, one shuraksha gas pipe, cloth filter, etc. In this process steam produced in one cooker is transferred to another containing shellac (seed lac), which melts it. The wastage of heat in the traditional method of shellac processing where large quantity of charcoal is used gave him this idea.
