Where is Pyrex cookware made?

Pyrex cookware is primarily made in the United States, although some products are also manufactured in other countries, such as France. The original Pyrex brand was developed by Corning Inc. in the early 1900s, using a special borosilicate glass that is known for its durability and thermal resistance. Nowadays, most of the glass bakeware sold under the Pyrex brand is made from soda-lime glass, which is produced in the U.S. and Mexico.

Why will a milk bottle crack if you pour hot water into it?

The milk bottle is made of ordinary glass with a relatively high coefficient of thermal expansion. Glass has poor thermal conductivity, so the inside of the bottle will be hot and outside cold. This temperature gradient will cause a stress in the glass and if the glass has small imperfections or flaws in it the glass will break. That is why coffee pots are often made of low expansion glass, like Pyrex, to prevent high stress.


What is a special glass that most beakers are made of?

Chemistry lab beakers may be made of borosilicate glass, including Pyrex. The glass is less likely to break when subjected to the temperature extremes found in lab work.
