If you're curious the only brand I could find easily purchasable in the USA that uses borosilicate glass is oxo. Their are some other results if you do a search on amazon, but I'm not very convinced those are really borosilicate glass.


In Texas, HEB sells its own brand of borosilicate glass cookware which is labeled as such on the front. All made in France.


If you want borosilicate Pyrex, go to church bazaars and yard sales. The old stuff is better anyway.


That seems the case for just about any product these days, unfortunately. In the modern world, all the products are cheaper but they all suck.


You can almost always pay more (and look harder) to get better items, in my experience.


pretty sure marinex is borosilicate too


You can relatively easily check this before buying, just look for the tint (usually best seen on the edges of the glass). Blueish = borosilicate, greenish = soda lime.


Don’t forget glowing green for uranium.

afaik that's a myth; the tint depends on other impurities in the glass.
