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.

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.

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