BTW YOU are the reason I'm in this mess, stripped of my net worth. I took your Yosemite Platinum course in 2000 and now have all my assets in potassium chloroplatinite. I won't stop until I get your fabulous results.
Hey GW,

Ummm.... sorry? Although I hear this alot "it's your fault I bought a bigger camera, spent all my kids college money on platinum and palladium, my wife left me because I was always in the darkroom..."

You can get Glyoxal from B&S, Artcraft chemical and probably other places as well. I don't know much more about it than what I posted before. It's thought to be less hazardous than formaldehyde, but I don't know that it's been studied nearly as much. I use formaldehyde as a hardener and wear nitrile gloves and a respirator with cartridges specifically for formaldehyde. Standard acid/gas type cartridges don't protect for formaldehyde.

Hang in there. It'll come together if you really want it to. I'm teaching gum-platinum in Yosemite in December... Oh, nevermind.
