Glass jar production technology mainly includes, raw materials pre – processing. The massive raw materials (quartz sand, soda, limestone, feldspar, etc.) are crushed to dry the wet raw materials, and the iron containing raw materials are treated with iron removal to ensure the quality of glass. Material preparation melting system. Glass matching material in the pool kiln or pool furnace for high temperature 1550~1600 degrees, heating, so that the formation of uniform, no bubble, and meet the requirements of liquid glass molding. Put the liquid glass into the mold to make glass products of the required shape, such as flat plate, various utensils and other heat treatment. Through annealing, quenching and other processes, eliminate or produce the stress inside the glass, phase separation or crystallization, and change the structural state of the glass. 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.
Trim the wick every time before lighting the candle, leaving 5mm or so in length. If the wick is too long, the candle will wear out quickly. Trim it to make the candle last longer. Moreover, if not trimmed, it is easy to have black smoke, and the wall of the candle cup is easy to be blackened. But why is it recommended to trim before burning, rather than after each burn? If you trim the wick before the candle is completely set, Therefore, after each burn, before the candle completely melts, it is recommended to straighten the wick and make sure it is in the center of the wax pool.
