What was the nature of this behaviour?
I think this thread is turning into a kind of witch-hunt.
- yes, it would be an improvement if 'Zone Imaging' and others practised 'evidence based photography'.
I just relized that must bewhy I never used them.The fumes at making, the stickiness of the cubes and their low melting point (I have not done the math on the exact one).
(Furthermore I grew up photographically without knowing about staining developers, in the major german textbook on processes staining development is not even mentioned...)
The major factor in pricing is the cost of the Pyrogallol, I did a quick calculation and buying a reasonable quantity of the chemicals came up with £5.89 per 100ml and of that £4.60 is for the Pyrogallol. It's likely Wet Plate Supplies paid less for their Pyrogallol, as prices have been rising.
Pyrogallol/Pyrogallic acid is a lot cheaper at Bostick & Sullivan, £176.50 a Kg.
For photographers in the United States and Canada, 510 Pyro is available for $16.95 for 100ml through Bostick & Sullivan. It is not a Zone Imaging product. It is prepared by Bostick and Sullivan.

The also offer PMK Pyro and Pyrocat HD, as well as the raw chemicals if you want to mix your own.
I have no connection to B&S other than as a customer of their platinum/palladium solutions.
ArtCraft also has the raw chemicals, including pyrogallic acid.Also Pyrocat HD with or without Glycol is available from Photographers' Formulary.
I have no connection to B&S other than as a customer of their platinum/palladium solutions.
Who prepares MSDS document? Is it the manufacturer or some independent certified chemical laboratory?
I have at least 750g of Pyrogallol, and plenty of Phenidone and Ascorbic Acid, so for me it would be cheap to mix a large quantity
Why not.510-Pyro does have a cult-like following in UK and Europe and there's probably enough market demand to keep more than one supplier in business if you choose to get into it. Given your knowledge, experience and background you might come up with a Pyro developer that's demonstrably better than other Pyro developers.
Yes, why notIt turns out I have far more Pyrogallol than I thought may be 1.5 kg. I may start selling 510 Pyro £10 per 100ml
Sounds good to me, IanYes, why notIt turns out I have far more Pyrogallol than I thought may be 1.5 kg. I may start selling 510 Pyro £10 per 100ml

When I made up Pyrocat-HD I just used distilled water. Ian's site has the formula: http://lostlabours.co.uk/photography/formulae/developers/devPC_hd.htmWhat's a good formula for pyrocat?
I agree with you to some extent,To quote, 'This further progressed to experimenting to make his own black and white developers after sparking a friendship with Jay DeFehr, the most celebrated photo-chemist of the 21st century' - citation? This kind of marketing hyperbole instantly puts me off the company.
Another quote: “The only problem with 510 Pyro is after you’ve used it regularly for a while and then go back to traditional chemistry, the results from it are different. It’s almost like 510 Pyro produces 4K pictures to the 720p of traditional stuff.” - this makes no sense, where is the comparison, process, methodology? - How about Pyrocat-HD?
- I am also on my way to establish such a similar company in Egypt.
I obtained commercial licenses and registered the company, but I am still waiting for approval from the Ministry of Environmental Affairs.
