TRUE: Pyrex, like all brands of glass bakeware, is subject to breakage due to thermal shock.

UNDETERMINED: Pyrex switched from using borosilicate glass to tempered soda lime glass only after Corning sold the brand to World Kitchen in 1998.
The common glass used to produce windows or bottles is primarily silica (75%), being the remaining 25% a mixture of Na2O (15 %), CaO (8 %) and Al2O3 (2,7 %). Sometimes some impurities are introduced in the glass, such as boron compounds, to increase the resistance to heat giving the commonly known Pyrex.
