I picked up a small (1L) Erlenmeyer flask at a brew shop a few years ago and the place has since closed down. I never used it much (wife thought it looked cool) until recently when I started doing proper starters.
I just poured about 100mL of near boiling water into it before suddenly realizing that I have no clue what kind of glass it is. I dumped the hot water back into the pot to cool there. It didn’t crack or explode, thank goodness.
What do you think the chances are that it’s a proper borosilicate flask? I’m thinking about putting it through a stress test (after this starter).
1. Safety goggles
2. Place empty flask in a bucket
3. Fill flask with near-boiling water
4. Fill bucket with ice water to meet flask water line
Should borosilicate survive such a test? Any bets on what happens?
