Re: Best way to buy Platino-Palladiotype chemicals

Sandy,

Thanks, as always for the comments! I'll get busy checking out
some of the sources you mentioned. I'm also glad to know about
that method of adding the Na2- might be worth learning about up
front! I hadn't heard of the Artcraft company- I'll check it
out. I was thinking that maybe a supplier who doesn't sell
exclusively for a specialty market might have cheaper prices,
at least for the more expensive materials. Maybe not, though!
