If nothing else I can use it to boil/cool the wort then dump it right into a flask.
I'd caution one thing - his appears to be of a special higher-than-usual tolerance to temp changes. It's boroscilicate just like ERlenmeyers are. I'm not sure if all or most coffee carafes are. I wouldn't want to rapidly chill one in an ice bath that isn't.

I wouldn't take the chance of rapidly cooling it, I would just use room temp wort and be done with it.

I know they can take rapid cooling from the brewing hot plate temps because it's how I make my tea for kambutcha and I put it in the sink with ice.. don't know about boiling temps though...

It should work fine. A flask is much heavier duty with much thicker glass but the coffee pot is a good alternative. I bet it can go from the stove top to an ice bath just like a flask can.

I'd use tin foil as a cover.

Here's some info on glass coffee pots: http://www.ehow.com/facts_5801232_sa...ffee-pots.html

Sounds like most of them are borosilicate glass. I'm guessing not laboratory grade, but sounds like they should do the trick.

This is exactly what I was thinking.

Good point. The handle IS a nice feature, and honestly, I bet you could boil in the pot with less chance of boil over without the tapered top!

Yeah - I broke my large erlenmeyer flask a few months ago. It cost me $40 and I only had it a month or so. I was not happy.

I'd be a lot less upset to break a $10 teapot or 2.

Although I will admit that a flask is a lot cooler than a teapot. A teapot will screw up the Dexter's Laboratory thing I've got going on in my basement. Maybe I can get a van de graaff generator to replace it.

I too would be concerned with rapid cooling in an ice bath. Also, would this work on a gas stove or just a hot plate/surface top? With flame, I'd be concerned with melting the handle or softening it enough to jeopardize the integrity of the handle. Looking forward to hearing the results!

Are you sure about the volume? A standard "cup" of coffee is actually 5 fluid ounces, IIRC. If that's correct, then this pot should hold roughly 900 ml.
