[quote="bmac"]I'm really itching to try some negs in pyro, but don't want powdered chemicals

Yes, there are some suppliers out there who do the lot in liquid form. Some while ago I purchased from Linhof & Studio in UK a version of PMK in two bottles. They did not make it up themselves and I know are agents for Lotus and also Bergger. If you want I can try and find out details of their supplier but it will be in Europe. What about Bostick & Sullivan ?
