Effect of Different Additives on Burning Efficiency of the Candles
نویسندگان
چکیده
Effect of different additives like wax (polyethylene), stearic acid, calcium stearate, alum, naphthalene and camphor was studied on the burning efficiency of paraffin-candles. It was found that burning efficiency, physical strength and smoke producing capacity of candles were influenced by even adding these additives in very small quantities. Burning rates were calculated while smoke generated during burning and appearances of the candles were observed physically. The present study can be very helpful in manufacturing economic, lasting and proficient candles.
