Glass making methods
In the glass production process, sand, soda ash, lime and impurities are used to change the color and transparency of the material obtained. When choosing, it is necessary to take into account not only the appearance of the future product, but also its characteristics. For example, tempered glass is used to manufacture products that need to be protected from various external influencing factors (temperature drops, mechanical impact, alkali and acid ingress to the surface). The production of sheet glass, including opaque and translucent products, is required for the manufacture of doors, table tops, windows and other flat types of products.
High quality is made according to existing technological standards. Careful attention is also paid to the state of raw materials. The choice of the best method of production depends on the purpose for which the product will be used, since different manufacturing methods affect the properties of the finished product.For example, for the production of culinary containers and laboratory flasks, glass must be durable, resistant to high temperatures and very durable.
To, you should first consult with a specialist who is well versed in the methods of manufacturing such products. The master, professionally engaged in the production of glass products, will give some useful tips. It will also help you choose the right composition of the raw materials, because by using special additives you can change some properties of glass products. The best example is lead glass, containing about 20% lead oxide. The use of such an impurity will allow you to add shine when cutting and cutting. Heat-resistant glassware used in food containers and laboratory equipment is produced by adding 5% boron oxide or aluminosilicate compounds.
Painters engaged in painting glass, should familiarize themselves with the methods of production, if they plan to work with glass objects. Colored glass products are made by adding iron sulfides to obtain brown and amber colors,chromium or iron for green shades and white cobalt for blue colors. Natural blown glass has a red-orange color without any chemical additives.
