Pyrex
(trademarked as
PYREX in caps
) is a brand introduced by Corning Inc. in 1915 for a line of clear, low-thermal-expansion
borosilicate glass
used for laboratory glassware and kitchenware.
Borosilicate Glass
is Much
More
Resistant to Thermal Shock.
Borosilicate glass
has a very low CTE (Coefficient of Thermal Expansion) whereas newer "pyrex" in lower case, soda lime
glass
has a very high CTE. It's for this reason that all high quality cookware is made from
borosilicate glass
.
