Question

What do you mean by following Pyrex glass?

Answer 1

In this question, the Pyrex glass is a type of glass which includes silica and boron trioxide as the main constituents of glass forming. The Pyrex glass is also known as Borosilicate glass because it contains silica and boron trioxide in it.

Complete step by step answer:
The Pyrex glass is a type of glass which contains mainly a substantial amount of silica that is $(Si{O_2})$ and more than eight percent of boron trioxide that is $({B_2}{O_3})$. Pyrex glass is also known as Borosilicate glass. Borosilicate glass or Pyrex glass is known for its durability and they are very highly resistant to heat, that is they have low coefficient of thermal expansion. Due to this property glass does not crack under extreme pressure. They have the ability to go straight from a freezer to an oven rack without any cracking because of its low coefficient of thermal expansion. They are used as glassware in chemistry laboratories, for kitchenware, for industrial settings ,in scientific lenses and hot mirrors, in aquarium heaters, in high intensity lightning products and in premium glass wines. Some common products that are made from Pyrex glass or Borosilicate glass are beakers used in laboratories, glass utensils, wine glasses, etc. Pyrex glass or Borosilicate glass has good chemical resistivity and also the optical clarity of this glass is very good.

Note: Always remember that the glassware that is used in all laboratories such as beakers is made up of this Pyrex glass or Borosilicate glass. This is because it has good chemical and thermal resistivity and also has good optical clarity by which the substance inside the glassware would be clearly visible.
