It's a big sturdy glass pot that is durable and effective and non-toxic. The added boron allows Pyrex to handle heat much better than typical glass, so Pyrex is commonly found in kitchens, laboratories, and in use with aquarium heaters (as the heaters are, necessarily, submerged in much cooler water). I didnt realize this when Rob called me and said Zambuto had a blank he could use for my mirror. "Pyrex" for all tubing. Borosilicate glass is better than regular glass for a wide variety of reasons. Borosilicate is different from regular glass because it has a much higher melting point and lower coefficient of expansion. We no longer refer to it as Pyrex, because Pyrex is a brand name. The other main competitor in this field is Anchor Hocking Glass Co., which has made a similar soda lime silicate glass product for over 60 years. Borosilicate glass was engineered in the late 1800s for use in chemistry labs with the goal of being even more heat-resistant than tempered soda lime glass. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. Best Value: Pyrex 18-Piece Glass Storage Set.
