candles originated in primitive times the torch. ¡£ Hominid fat or things like wax applied to the bark or wood, tied together, caused by the lighting of the torch.  In the 3rd century BC, about the beeswax candles may see today is a prototype.  In the West, there is a period, the temple is in beekeeping, used homemade beeswax, mainly because of the Catholic Church that beeswax is a symbol of a virgin pregnant, so put the light of pure beeswax as the souls on the altar in the church . From the existing literature, the beeswax in China and the West generally the same time, Japan is in the Nara period (710-784) imported from China such candles, candles and modern compared to many ancient candle inadequacies of the .Tang Dynasty poet Li Shangyin "He candle when the total shear Xichuang" poem. Why should poets shear candle? At that time, candles candle hearts are with thread Guocheng, vertical flame in the center of the inability to burn out and charring, it is necessary from time to time with a pair of scissors will be the end of the residual candle heart cut.  This is a troublesome matter, in 1820, French-Pakistan hysteria out invented three thread woven candle heart, heart candle burning natural release, Alice is the end of the lateral to the flame, and can complete combustion.  However, candles still needs to be further improved, it is generally the material has many shortcomings of animal fats, to solve this dilemma is not for the Leer and others. June 1809 to July, the French Branch home Shefule received a letter from a textile mill, to his analysis, they identified a soft soap sent samples of ingredients.  He took the letter thought for a very long time, I thought: We should study soap, it must start from the raw material oil. The equipment is very simple, plain experimental school, he studied saponification process requires the use of oil.  After experiments, the first time he has found such a fact: in all oils, regardless of their source, the content of fatty acids account for 95% of the remaining 5 per cent is generated in the process of saponification of glycerol. He made clear by studying the nature of the saponification process, but he still has a major discovery: Oil was caused by the candles, because there are glycerol, combustion flame with smoke and unpleasant odors. If using candles made of stearic acid, not only the flame burning bright, and almost no smoke, do not pollute the air.Ëß Shefuleer told his discovery build a Lussac, and suggested that the two jointly study how to solve this specific problemThey have used the oil alkali saponification, and then get the soap with hydrochloric acid decomposition, stearic acid extracted.  This is a white material, hand touched a greasy flu, it made candles with a soft texture, and the price is cheaper. 1825, and build a Lu:sake Shefuleer was stearin production paraffin candles patents.Stearin the emergence of paraffin candles, lighting in the history of mankind has created a new era.  Later, it was discovered in North America in the oilfields, so the oil can be extracted from a large number of paraffin wax, better candles have been so popular in the world to promote.
