In your kitchen you probably use some kind of glass to cook with. Pyrex measuring cups are used to measure out ingredients. A casserole might be baked in a Corningware dish. A stove top could be made of glass. The glass commonly used in cookware is called borosilicate. Borosilicate is made by the addition of the element boron. This treatment gives the glass a highly valuable quality, resistance to temperature fluctuation. Without the addition of boron the glass might destabilize if it was exposed to the heat of an oven then a splash of cold water. The German scientist, Otto Schott is recognized as the inventor of borosilicate (dyer, 2002); however, the rail road industry is responsible for bring it in to our kitchens. Rail road workers used to use lanterns as a beacon to alert on coming trains to avoid collisions. If the glass in the lantern broke lives could be at stake. The Corning Company hired, Ph.D. Chemist, Eugene Sullivan. In 1909 they began sale of Nonex, a lead borosilicate glass, for use in lantern globes. It worked so well that in the following years people bought 68 percent fewer lantern globes. After crashing the rail road market they were forced to expand in to other markets (Davila, 2007). Nonex was reformulated, removing the lead, so that it could be used for cookware and given the familiar name Pyrex.
quartz glass (nearly pure SiO) has higher resistance to temperature fluctuation, but also a higher price. if you use quartz cookware that is neat, but it is probably Pyrex.

∙ 13y ago1. It has a very high melting point (about 1700 c), (also retains shape in high temperatures).
2. Doesn't break as easily, is more "shatter proof" due to lower thermal expansion.

Explain why glass which is mainly made up of Sio2 is often used to make ccokware?
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.

What utensils can be used on a induction cook top?
In general, if a magnet attracts to the bottom of the cookware, it can be used on a induction cooktop. Aluminum, glass, ceramic, copper are not suitable for induction. Cast iron and some stainless steels are good. Carry a small magnet when shopping for induction cookware. The manufacturers will often state "induction ready" or similar wording on the packaging.
Where can one purchase Nigella Lawson cookware?
Nigella Lawson brand items for the kitchen are often of a unique and practical design. Nigella Lawson cookware can be purchased directly from the Nigella website.
What does boron have to do with glass?
Boron is present in borosilicate glass in the form of boric acid. It is a flux which allows silica to melt at a lower temperature. Borosilicate glass is most often used as cookware (most common brand is Pyrex) and laboratory ware (best known brand is Schott) because of its very good thermal resistance. Borosilicate was developed by the German glassmaker Otto Schott in the late 19th century)
Ionic compounds often have higher melting point than metals. Using at least 2 properties of ionic compounds explain why is cookware not made from ionic compounds?
1) Ionic compounds are not good heat conductors 2) Ionic compounds are not malleable
What cooking utensils are essential?
The important thing is that you give them utensils which are safe and won't damage your cookware if it's teflon coated. They would need a whisk,a ladle or two, and a spatula. Silicon spatulas are often good in place of whisks and less likely to damager your cookware.
