Lab glass

[Darkthirty]

I have very little experience in this field. And have used a simple tall / narrow glass flower vase. For cold processing silver plated copper. And had no issues.
But now I too use glass coffee pots from coffee makers and French press beakers.
Something to keep in mind if you decide to use "Pyrex" dishes.
The new clear stuff is different than the original.
The new version is more prone to thermal breakage, than the older versions. If you do a Google search about "exploding pyrex" , there's plenty of info out there.
It's easy to tell the new stuff. As it has a different color.
If you look at it through the edge. It has a lite blue color.

I looked at some today. It states that it is tempered soda lime glass, with a warning about scratches making it prone to breaking.
