I've been boiling in a separate pot then pouring the wort into the flask. When boiling directly in the flask I'd use a funnel and pour small amounts and shake the crap out of the flask so that it would dissolve quicker.

Well, yes, but the magnets themselves are probably ceramic. I don't boil mine, just to be safe.

Waste of hops.

Follow up question, though: what are some methods for avoiding boilovers in a flask aside from fermcap? I am always boiling over when I boil in the flask...

Yep, but I have done it over and over and they have yet to demagnetize. The day they do, I'll buy a new one. Hasn't come up yet.

I add the DME first and then add water, slowly and stirring vigorously, until I have the proper starter volume. It was a bit of a pain the other day because our water has been very aerated. But I had no clumps because I took my time. I also added 1/4 tsp. yeast nutrient. As far as boil overs go I just keep my heat low and once it gets to a more vigorous boil I lower the heat, even take it off the burner for a minute. But I kept it slow and watched it like a hawk.

I would like to try fermcap though.

Hmmm...wondering why people add DME, stir well, then heat it all up. I usually just add DME (as 944 does: measure on a sheet of paper then curl into a funnel), add water, then put on stove. As it's heating it always seems to mix itself up fine. By the time it boils it's always a pretty uniform mixture.

Seems like it just eliminates a step. But maybe I'm missing something?

Oh yeah, and Fermcap+low temps usually work for me. But I still get the occasional boil over. Might have to move to a larger flask.

are you putting direct flame on the flasks? i have read this should not be done ever, even though they are boro silicate glass or whatever? i wanted to do it this way but from what i read they can spontaneously explode even if most of the time they won't. anyone confirm or deny?

Actually most flasks are designed for direct flame in the lab. Like a bunsen burner. It's the coils on electric stove eyes that are not good, without a trivet underneath.

its funny my mother in law told me a story today about how she blew up a flask she put on her gas stove. She said it just popped and made a mess, didn't explode though. funny coincidence. anyways I looked it up again offsite and did confirm its not the best idea...found this too...http://unitednuclear.com/index.php?m...220e7afad21767

I just figure it reduces the chance of clumps stuck on the bottom and I was worried they would scorch the bottom. It was a bit extra work but not too bad.
