Heat resistant glass (usually borosilicate glass, with brand names such as Pyrex) is a very versatile cooking material. You are probably most familiar with it as casseroles. It is good for food because it is inert; that is, it doesn't react with anything in food. It's also very hard so it will take quite a bit of abrasion when you need to clean it. It's also cheaper than metal.
(hint: what properties does sio2 have because of its structure)
Glass that is made up mainly of Sio2 is often used to make cookware because it is very durable. The substance also has an incredibly high melting point.
225 grams SiO2 0.30 kg glass*(1000 g glass/1 kg glass)*(75 g SiO2/100 g glass) = 225 g SiO2
A typical glass is prepared from 75 % SiO2 and 25 % Na2CO3.
Glass is Crystaline SiO2
The formula "SIO2" is commonly known as silicon dioxide. Silicon dioxide has a wide range of purposes, mainly being glass manufacturing. In nature, silicon dioxide is commonly found as sand and quartz.
SiO2
Common glass is made from sand, SiO2, Na2O and CaO. Concrete is a mixture of rocks (aggregate), sand, and water.
glass is the most common material containing fused SiO2
There are a variety of types of glass, but the most usual ingredient of glass is silicon dioxide (SiO2).
