Glass stands for rigid material that is homogeneous and characteristics. Usually caused by the sudden cooling of the material melts nuet. That makes it not a crystal. For example, sugar, which melts, melting and rapid curing may drip onto the skin with cold water. Solid sugar will look like a single body. Does not demonstrate as crystals. This can be observed from a broken crack, which look in detail. (Conchoidal fracture) in a variety of ways to kaeosamarot by selecting the raw materials must be calculated to determine the quantity of the substance to be used in the Batch, because the message that you want to use in the Batch will be derived from the reaction of the material during melting raw materials to change tha.Ngakhemi and structure will cause air bubbles must be removed by commercial products that require more specific shape to make a thermal process to eliminate the Stress that to happen because of the cool down quickly, and improvements to the glass with the strength created by baking glasses. (Temper)Glass that is mentioned in this article refers only to the glass is made of silica (silica), lyrics, pure, transparent glass, the surface is quite hard to make strong corrosive chemical reactions and biological sluggishly against feature that makes it useful to use its glass. However, the glass is hard but brittle fracture, crack and the sharp details. The properties of glass, this can be changed easily with other substances into the mixing glass or body condition by using the thermal glass is generally made from silicon dioxide (SiO2-silicon dioxide) which may be in the form of chemical compounds in the quartz mineral (quartz) or in the form of polycrystalline sand. Pure silicon alone service. Has melting point at 2000° C (3632° F) in order to facilitate the production process, there will be a mix of 2 types. The first type is the solo da (Soda Ash), which is the main element is the sodium carbonate (sodium carbonate-Na2CO3) or compounds such as Pro secularization Siem Siem Pro secularization carbonate to the melting temperature lower that 1000 ~ 1500° C, but this, however, will result in the side, making the glass melt water. So it must be another substance is limestone, which contains the core elements are calcium carbonate (calcium carbonate-CaCO3) (when in the glass becomes calcium oxide, calcium oxide-CaO;) in order to make the glass is not soluble. The composition of the glass container is made available generally, such as glass or clear glass. Each element is approximately as follows: SiO2 70% Na2O 15% CaO 8%And other elements such as MgO, Al2O3, a little bit of K2O, etc.There may be other types of special glass which filled the other raw materials to optimize the properties of glass such as.Additional lead (from the raw materials, such as Litharge that Lim;), and made of glass, so that flesh PbO in the glass. The meat tough and flexible glass sparkle, which is called the Crystal glass in General that additional barium and zinc oxide (ZnO, BaO) to help make glass look like crystal glass without lead, etc.
