Pyrex (trademarked as PYREX and pyrex) is a brand introduced by Corning Inc. in 1915, initially for a line of clear, low-thermal-expansion borosilicate glass used for laboratory glassware and kitchenware. It was later expanded in the 1930s to include kitchenware products made of soda–lime glass and other materials. [1]
As a rule of thumb when substituting glass in a recipe that calls for metal, chef David suggests lowering the temperature by up to 25°F and extending the baking time by five to 15 minutes, and ...
The manufacturing process for soda–lime glass consists in melting the raw materials, which are the silica, soda (Na 2 O), hydrated lime (Ca(OH) 2), dolomite (CaMg(CO 3) 2, which provides the magnesium oxide), and aluminium oxide; along with small quantities of fining agents (e.g., sodium sulfate (Na 2 SO 4), sodium chloride (NaCl), etc.) in a glass furnace at temperatures locally up to 1675 ...
A dash of baking soda increases the Maillard reaction (a.k.a. the chemical process that creates a golden exterior) in recipes like zucchini bread and sugar cookies.

Fire-King is an Anchor Hocking brand of glassware similar to Pyrex. It was formerly made of low expansion borosilicate glass and ideal for oven use. Currently it is made of tempered soda-lime-silicate glass in the US [1] and borosilicate in Japan [2]

The lids of CorningWare are typically made of Pyrex. Though some early lids were made of Pyroceram, most subsequent covers have been made of borosilicate or tempered soda-lime glass. Unlike the cookware, these lids have a lower tolerance for thermal shock and cannot be used under direct heat.
