Customer Review

Reviewed in the United States on July 18, 2018
So I bought these before doing some research about why some glass is so much cheaper than others. These are fine for measurements but I would never recommend them for heating use as they will not hold up.

In short, there are two types of B. glass, the true kind with Boron are lab quality and are more expensive... sets like this are made with soda lime which will not hold up to sudden changes in temperature. If you are working with hazardous chemicals, thats gonna be a bad time.

Similarly, all capitalized PYREX with the copyright symbol is the old lab quality stuff while pyrex (NOT capitalized) is the soda-lime glass from china.

TLDR: If the price is too good to be true... be prepared for a chemical spill
