I've always said I'm not a smart person but have lots of common sense. Well this morning, I realized I don't even have that going for me.
Making a yeast starter for tomorrow's brew day I had my flask on the stove boiling and I wanted to boil some water to soak some hop bags in so I grabbed a pyrex bowl. Oh yeah, I mean oh no! Don't do that.
Luckily for me, my wife was at the gym and I was 15 feet away when it exploded all over the place. It was a small one and only had 1/2-3/4 cup of water in it so it wasn't a water mess but little chards went all over the place. Took me 45 minutes to track them all down with the broom and vacuum.
It seems there's confusion on the net whether this is ok but I now know better. European Pyrex is made from borosilicate glass, the same as in laboratory's equipment; American Pyrex is made from common soda-lime glass. So, unless you have one made of borosilicate glass, DO NOT TRY THIS AT HOME.
