Thank you

I'll try it with the crystalline citrates. It's what's on the shelf anyway.
I can do the calculations for all forms of citrate in the VWR catalog and
post them. Do I have permission to post the entire recipe, or is it under
copyright? It's so confusing these days.

As far as stability goes, I have unlimited access to desiccant packs. They
throw out about 6 x ~150 gram packs each day at work. I'll try to do some
studies with and without desiccants over a week or two, in my copious free
time (it's so hard to convey irony in e-mail).

I plan on using crane's platinotype (cover).
