Candles PNG
Avus is among the first inventions of Antiquity, as can be seen from candlesticks found in Egypt and Crete that are at least 5000 years old. In the Middle Ages, candles used in Europe were made from tallow. According to a tax list of 1292, 71 candle makers lived in Paris.
In the 1800s, French chemist Michel-Eugène Chevreul produced stearic acid, which is used to make better quality candles by separating the fatty acid from the glycerin in oil. Later on, new processes were learned in making candle materials. Apart from stearic acid, two other important materials have been found: sperm obtained from the skull cavity of the sperm whale, and paraffin, a by-product of petroleum. After these inventions, the mixture prepared with paraffin and stearic acid became the basic material of the candle. However, although the mixture that is called wax today, that is, stearic and mixed with raw paraffin, is roughly described as wax, in reality, the mixture of these two is insufficient for a sufficient quality as a wax. If three percent ceresin and 5 percent hardening wax are added to this mixture, the mixture will achieve a full consistency and will be more transparent and hard. When burned, the wax will harden and burn thirty percent longer than other mixtures. In frontal waxes, on the other hand, this mixture will be as preliminary and hard as it should be, with a clear foreshadowing and marble-like appearance. In addition, this mixture will maintain its hardness without softening too quickly, as in other mixtures at 40 degrees in summer heat. Many people do not use these mixtures together. It doesn't need it. When Burning from the Candle, the heat from the flame liquefies the solid wax at the bottom of the wick. This melt rises from the wick by capillary action, and then evaporates due to heat. The wick of this
candle must be cotton thread. A flame is also formed by the combustion of wax vapor. This continues in such a cycle until the hunt is over. Today, candles are used in very different places, far outside of the known patterns. For this, candles are divided into classes according to need: consumed candles, decorative candles. While the content of the raw material does not change in any way, the burning time, burning shape and hardness of the material differ due to their contribution. Increasing the quality of paraffin with stearic acid and other by-products. The softer the candle, the shorter the burning time of that candle will be. The burning time and quality of the candle is directly proportional to the hardness of the material and its contributions. Candle burning areas must be windless and drafty areas. During the burning of the candle, the fire in the wick must burn upright without swaying to the right and left. If there is a contrary situation, there will be invisible works in the environment where the palm is burned. The oil content in the candle can be understood by touching the paraffin. In this, you can measure the paraffin with the oil that comes into contact with the friction by hand crushing and touching. If you get the oil of the candle with this touch, it is a sign that the oil of the candle is too much. This situation is characterized as a material that is not preferred very much in wood burning and room temperatures. It is necessary to read the details very well and apply them correctly regarding the construction of the Avus. For this reason, it is dangerous to make candles in the home environment. If the candle is left on the fire for a long time after the mixtures are made, it may boil after a while and its vapor may catch fire. For this reason, it is very dangerous to heat the paraffin and leave it on the fire.
