My dad found an old Kimax (26500) 1000mL Erlenmeyer flask that has been in his attic for the last 30 or so years and gave it to me. I'd like to start using this to make starters, in conjunction with a stir plate. I am concerned about the ability of the glass to handle the heat from my electric (glass top) range, and then the cold of an ice water bath. I'm pretty certain that these are used in a lab, but in my chemistry classes, we used gas for heating, rather than electric.
Mostly, I'd just like a little more confidence that the flask won't shatter while I'm in the midst of heating a starter. Will it handle the direct heat from the electric stove top?
