UN Heavy water
I was looking at the United Nuclear website and noticed they started selling D2O. I am interested to know of anybody knows where UN (or
anyone) gets deuterium oxide. It would seem like the type of thing that would be extremely expensive but on their website it only costs $12 for 10
grams (yes I know that's sort of a lot of money).

You could always make it yourself, via the Girdler sulfide process...

When it comes to isotopes, deuterium oxide is about as much an item of commerce as things get. It's from the D2O that the plethora of other
deuterated compounds are derived in one way or another and hence it is relatively 'cheap' as feed stock.
Interesting note on the Girdler sulfide process, I'd never heard of it before. Previously I only knew of heavy water being isolated by electrolysis.

I bought a bottle of D2O from UN, as a curiosity and for its educational value for kids. A $20 demo would be to freeze it into an ice cube, then drop
it in a glass of (ordinary) water and watch it sink.
Any other SF Bay chemists?

You probably just forgot but we talked about it back in October 2011, I'm sure you saw the thread, then it was mentioned again in 2013.

Although IIRC there was a stretch of time you seemed gone for a while, work, or school or something related so maybe you missed the discussion.
The process does not reach a high concentration so maybe that is why it is seldom mentioned.
