Question

Glass apparatus is made up of _____________ or ___________glass

Answer 1

Hint : Glass is a transparent material. Glass can withstand high temperatures. Glass can be destroyed by Hydrofluoric acid. Different materials are made from different substances, some use natural materials and others synthetic.

Complete Step By Step Answer:
Glass apparatus is composed of Silica material. Glass apparatus is made up of Pyrex or Borosilicate glass. Borosilicate glass is composed of silica and boron trioxide as the major content. Borosilicate glass contains low coefficient of thermal expansion ( $3x{{10}^{-6}}{{K}^{-1}}$ ). Borosilicate glass can withstand thermal shock compared to other glass.Borosilicate glass is used for laboratory experiments. Borosilicate glasses can be called crown glass which has low dispersion value and low refractive index value. Borosilicate glass has a density of $2.23g/c{{m}^{3}}$. Borosilicate glass can withstand a high temperature of ${{330}^{o}}F/{{180}^{o}}C$. Borosilicate glass can be classified based on their amount of boric oxide and silica. The sub-types of borosilicate glass can be regarded as Alkaline earth borosilicate glass, Non-alkaline earth borosilicate glass and high borate borosilicate glass. Borosilicate glass has major applications in Rapid Prototyping, Optics, Lighting, Cookware, Electronics and Health science. Pyrex glasses have higher thermal and chemical resistance. Pyrex glasses have low alkali content which is responsible for high corrosion resistance. Pyrex glass is made up of soda-lime glass. Soda lime glass can be softened, remelted and recycled
Soda lime glasses can also be blended with magnesium oxide, calcium oxide or aluminium oxide which contributes for durability. Soda lime glasses can withstand a temperature of $573-{{564}^{o}}C/1063-{{1047}^{o}}F$. Soda lime glasses are composed of $70$ Silicon dioxide and $15$ sodium dioxide $70$ $15$. Soda lime glass has light transmission properties, low melting point which contributes application in windows, drinking bottles
