Glass jar is a kind of chemical vessel commonly used in food packaging, gift packaging and medicinal packaging. Glass is a non-crystalline inorganic non-metallic material, generally with a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda, etc.) as the main raw materials, and a small amount of auxiliary raw materials.
Its main components are silicon dioxide and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main composition is silicate double salt, is a kind of amorphous solid with irregular structure. Candles are thought to have originated from the torches of primitive times, when primitive people put fat or wax on bark or wood chips and tied them together to form torches for lighting. There is also a legend that in the ancient period of the pre-Qin Dynasty, someone tied mugwort and reed into a bunch, and then dipped in some grease lit for lighting, and then someone wrapped a hollow reed with cloth, filled with honey wax lit.
The burning of candles we see is not the burning of paraffin solid, but the ignition device ignites the cotton core. The heat released causes the paraffin solid to melt and then vaporize to form paraffin vapor, which is flammable.
When a candle is lit, it burns a small flame at first and gradually grows larger. The flame is divided into three layers (outer flame, inner flame and flame core). The flame core is mainly candle vapor with the lowest temperature. Internal flame paraffin combustion is not sufficient, the temperature is higher than the flame core, containing carbon particles; The flame is in full contact with the air, the flame is the brightest, the combustion is full and the temperature is the highest. Thus, when a match stick is quickly placed flat into the flame and removed about a second later, the part of the match stick that touches the flame first blackens.
