Pyrex is the trade name of a Corning low thermal expansion glass. All Pyrex is glass, not all glass is Pyrex.
It is a glass formulated to resist thermal shock.
Unfortunately, this depends upon whose Pyrex you are considering. The original Pyrex was a borosilicate glass, which has a low thermal expansion. The Trademark owners have allowed the name to be used nowadays by some manufacturers who use tempered soda-lime glass. But some licensees still use a borosilicate glass.
Pyrex portables can be purchased at stores such as Walmart, The Bay, Sears and Canadian Tire. If you are looking for an online supplier, you can purchase them at Amazon.
