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.

Explain why glass which is mainly made up of Sio2 is often used to make ccokware?
Glass, which is primarily made up of SiO2 (silicon dioxide), is used to make cookware because it has a high resistance to heat, is non-reactive to acidic or alkaline foods, and is easy to clean. These properties make glass cookware a practical choice for everyday cooking needs.
How much of SiO2 would you start with to prepare 0.30kg of glass?
To prepare 0.30 kg of glass, you would need to start with at least 0.30 kg of SiO2 because silica (SiO2) is one of the main components of glass. Keep in mind that the actual amount of SiO2 required might be slightly higher to account for losses during the glass-making process.
What percentages of silica soda and lime make glass?
A typical glass is prepared from 75 % SiO2 and 25 % Na2CO3.
Why is SiO2 used in cookware?
SiO2 (silicon dioxide) is used in cookware because it is durable, heat-resistant, and non-reactive with food. It also provides a smooth surface that is easy to clean and does not release any harmful chemicals when heated.
What makes glass transparent?
Glass is Crystaline SiO2
What is the formula 'SIO2' for?
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.
Glass chemical formula?
The chemical formula for glass is not a fixed one, as it can vary based on the type of glass. However, one common type of glass is soda-lime glass, which has the general formula of SiO2 - Na2O - CaO.
What combines to make glass and concrete?
Common glass is made from sand, SiO2, Na2O and CaO. Concrete is a mixture of rocks (aggregate), sand, and water.
What is the Common material that contains fused SiO2?
glass is the most common material containing fused SiO2
What is glass of?
There are a variety of types of glass, but the most usual ingredient of glass is silicon dioxide (SiO2).
What elements combine to make glass concrete?
Common glass is made from sand, SiO2, Na2O and CaO. Concrete is a mixture of rocks (aggregate), sand, and water.
A lead glass is prepared by melting 20.0 g of silica sio2 and 80.0 g of leadii oxide pbo what is the mole fraction of sio2 in the glass?
48.15 Mole% Silica and 51.86 Mole% Lead Oxide. 20% Silica - Molecular weight 60.1 = 60.1*0.2 => 0.3332779 80% Lead Oxide - Mol Wt 223.2 = 223.2*80 => 0.358 Sum of mole wt -- 0.6912 Mole % Silica = 0.332/0.6912 = 48.14 Mole% -- Balance Lead Oxie...
