Hey.

Friend of Ruthling's.

You may want to try something as simple as sugar crystals when it's supercooled...they make decent nucleating agents.

The other thing is to use a well-scratched container--no polymers. The scratches give high-energy states for nucleation/growth.

Or-or...freeze some glycerine at ~0C in your freezer (it should give up at some point, especially if seeded with sugar and/or flawed containment), crush that, and drop it in the supercooled glycerine.

That crap gave me the hardest time when I was working on a non-aqueous electropolish for Zirconium.

Hi,

Thanks for the suggestions. I did try using diatomaceous earth to provide nucleation centers, but did not think to try sugar.

I did try low temperatures; the glycerol did not give up and freeze, and probably remains a glass.

I found an alternative material that did the job, however. More later.

Cool (ha!) I'm interested to hear what it is...I'm still not sure about the use of Talisker as a cooking ingredient...but I'm always interested in chemistry (3 minors)

Hi,

I've friended you. See my post titled 'DOME', about halfway down.

Let me know how it works...I've crystallized DMSO and 1,4 butanediol.
