I'd give Artcraft my seal of approval too. While the folks at B&S have it, I MUCH prefer Mike at Artcraft. If you do buy it, anywhere mind you, And you decide to make platinum palladium prints, you give your self another alternative to the sodium based palladium with that. It will produce cooler prints than the sodium version.

I've launched myself into wanting to start making Albumen Silver Prints. Recipe call for 500 ml egg whites, 2 ml 38% acetic acid, and 15g Ammonium Chloride. Where do I get Ammonium Chloride? Isn't it a commercial product or something that I can find in a hardware store or super market? Can I substitute salt (Sodium Chloride) ??? Cheers, Bogdan
