PYREX vs pyrex

Although the legal guidelines of heating and cooling shortly can clarify a few of these cases, there’s one other issue at play: Glass sorts. And, you’re not imagining it: Situations of glassware breaking have elevated within the final decade or so. All of it comes down to some capital letters. 

Based in 1915, Corning Glass Works created the Pyrex line of glass wares. Utilized in each properties and scientific labs, Pyrex grew to become the go-to for all the pieces from beakers to pie plates to sturdy glass casserole dishes. This period of glassware was made with borosilicate glass—created from the compounds of silica and boron trioxide—recognized for its potential to be majorly warmth resistant. So warmth resistant, that it might face up to a 333 diploma temperature change with out flinching. (Learn: Violently breaking.) These merchandise are denoted as capital P, PYREX.

In 1998, Corning moved the kitchenware aspect of manufacturing to a different firm, Corelle, who nonetheless produces glass merchandise for the house as we speak with the identical Pyrex identify, however in all lowercase (pyrex). One of many main issues they got down to sort out was, funnily sufficient, breakage.
