A simple solar machine has been developed to melt paraffin wax for candle production. The present solar technology is a safe, convenient method of candle production and obviates any type of care or attendance during the wax melting process as required in old methods based on conventional fuels. It is quite useful in the cottage industry and generates employment. On the demand of professional candle makers, the solar candle machine has been further improved enabling manufacture of candles in the night as well. For it, Transparent Insulation Material has been successfully tested over the absorbing surface in the solar machine, which was found to prolong the storage of molten wax for candle production after sunset. The present paper describes the complete solar technology for candle production, including the advantage of the improved model.
