RE: pure vs impure Re: .... ferric citrate? can I make it?

Jude,

You can always contact Mike about chemicals not listed online. As Judy
pointed out he can special order items he doesn't normally carry in stock.

I've always had great service and experiences with Mike Jacobs.

Hi All,

I just rechecked Artcraft Chemicals and did not find ferric citrate listed
(as I didn't the first time I checked)....so maybe they are not carrying it
anymore - unless it is listed by another name or not in alphabetical
order...or I need new eye glasses...anyway...

...it sounds like Dan has solved Charles' need for ferric citrate for the
moment. But I am wondering if the $80 lb is unpurified (Science Lab also
offers 17%.) and if unpurified ferric citrate will be just as effective for
variable contrast control in VDB. Any of you know - by direct experience or
by theory?

JT
