Hi John I did try to mix Pyro 510 after watching your procedure - you make it look so easy!. Despite purchasing all fresh chemicals from a reliable source in Australia (Gold Street Photographic Studios) the result was a complete failure. I am using a Jobo CPE2 and developing FP4 sheet film for around 7 mins - slowest rotation speed @ 20 deg C. What I get is a heavy general pyro stain - but no image! Siver reduction is not happening.......... What should be clear film edges are also stained - which suggests heavy oxidation taking place. It points to either the Vitamin C or Phenidone not working????? The film was exposed @ 64ASA. Linhof 5x7 210 lens…… In desperation I have tried the the Zone Imaging pyro 510 and it works fine using 1:100 and the Jobo processor as above. I have just watched your Pyro, Pyrocat Tips video and wonder whether the 80 deg C use to initially heat the TEA has killed one of the ingredients? eg Vitamin C. You mentioned in that video to keep temperatures to “warm” Rather than hot……. Advice appreciated. PS for anyone using 510 make sure you mix it really well into water before use- 2 minutes min.
Interesting. It's not possible you mixed up fix and developer is it? If you fixed the film first and then stopped and then developed it would do that very thing. No image but general stain. How many times have you tried your own 510?
Greetings from Sydney, just discover this channel, after the pandemic, love it and immediately got the book.. looking forward to get it send out here. Now..inspired to do Pyro dev. I looked the 510’up in the darkroom cookbook formula 53 gives the 510. It uses 0,25 gr of Phenidone, I guess it’s not that big of a deal, but what’s the reason..? Anyway thanks for the channel!!
Hello to the great city of Sidney! The Darkroom Cookbook has an outdated version of the formula. It was revised by DeFehr to better balance the developing agents. You'll see the new formula in my book. Thank you for buying it!
WoW !! What a HUGE container of TEA -- from where do you source it and your Pyrogallol and other chemicals please as I am 'Running Out ' of a Huge stash given to me by a Camera Club member YEARS ago -- I hate to know what they COST nowadays !! When I was in the British Army (RAMC ) doing Pathology I could order chemicals and the British Government paid ! I made up my own Developers in BMH Iserlohn Germany just as the famous ADOX Films were coming out and the AGFA ones of course.
I state in the video to raise the temperature to 80C. The flashpoint of TEA is around 179C, a great deal more. Follow my instructions and you'll be fine.
@@PictorialPlanet Thanks for that. Even then however if heated too fast, a microwave is just the way to do so, TEA will give off toxic vapours. It should on safety grounds really only be heated, under control within a vapour cabinet. We never see any advice on such things...so it would be nice to see for example, istruction to folk to always read Safety Data Sheets on each and every ingredient. I won't be making 510 anytime...nothing personal to anyone or anything like that but in all seriousness, I wouldn't waste 50g of expensive Pyrogallol (which as I am sure you know, needs VERY VERY careful handling due being the single most toxic raw chemical currently still available), we have seen some shocking advice on this, dangeous in fact in some cases! For us, that chemical is much better used for PMK Pyro, a much nicer developer which reaches into the shadows and full tonality that eludes 510. Give it a go, you'll soon see :)
It is possible to use phenidone 1% or 2% solution in propylene Glycol, as you suggested in your FX-55 video, in this (or, any other like PC-TEA)TEA based developer?
Yes, you could but beware. Bear in mind that 510 gets (and needs) its alkalinity from the TEA so to dilute it too much with glycol will affect the developer negatively. Use a 5% phenidone solution in glycol. With a 5% phenidone solution you'd need 5ml, not enough to make a real difference. I'm using the original formula for that calculation. You can use your 5% in all other developers too.
Hi John, I have your book and discovered your YT channel (somehow) right at the start = thanks for your work and sharing with the analog community! One question: there numerous pyro developers available, Ichor being the last contribution by Jay de Fehr (though the recipe for this one is not disclosed as far as I know). Do you have your own experience with Obsidian Aqua and Ichor and could compare these to 510-pyro? I was among the first to order Ichor from Jay but the orders for non-US residents were cancelled due to the logitistic issues related to shipping chemicals. Still I have the option to use 510-pyro (I have bought it from Rudiger) and OA.
First, thank you for buying my book and your kind words, Daniel. I’m glad we have connected here. I have not tried Obsidian or Ichor. When I started using 510, and tested it for my book, I thanked Jay for one of the best developers I’d ever used. It suits me perfectly as a very fine grained pyro developer that keeps for donkey’s years. It’s not the only developer I use - horses for courses and all that - and I’ll probably cover others in future videos I’m sure. Thanks for taking the time to comment, I really appreciate it.
Hello Paolo! It's preferred to use an alkaline fix but not essential. It's worth trying the developer anyway because it's very good. I have videos on making different fixers that are matched to pyro developers too if you can buy the chemistry.

@@PictorialPlanet Thank you John! I'll give it a try soon, because I think it provides the advantages I'm looking for. I found a neutral fixer by Rollei (RXN), it should do the job. I want to thank you for your videos: they're very well done and with passion. Greetings from Italy!
Hi John, I'm making a batch of 510, only I've just retrieved my triethanolamine from the garage and half of it has crystalized. Is it still usable? I've noticed ACP pure sell it, but it's a clear liquid? Kind regards, Kit
Hello John, I have two questions: 1 - I have your book in an older version, does the new one have more recepies and techniques? 2 - Why do we use TEA with 510-Pyro (Pyrogallol) and Propylene Glycol with Pyro HD (Catechol)? Thank you for sharing your knowlodge.
The new addition does add some new and very good formulas. I've rewritten a lot too adding more personal experiences. If I had an older version I'd definitely want the new one. Now, to question 2. TEA is alkaline and at a nice alkalinity for pyro and phenidone. That's why 510 has no second accelerator like pyrocat has. With glycol it's more or less neutral so won't develop silver halides without that accelerator, in pyrocat's instance, potassium carbonate. Metal salts such as potassium carbonate won't dissolve in glycol (or TEA for that matter) so we can't make a single liquid developer like 510. It was very smart of Defeur to create 510. He had listened to Patrick Gainer talking about using TEA as a alkaline preservative (PC-TEA for instance) and realised that the TEA was the trick to making a very good pyro developer.
Hi John! Nice video as always. While I appreciated your warnings about the toxicity of Pyrogallol, the doctor in me really cringed watching you mix this up without wearing gloves! I always wear gloves and a mask when mix this type of chemical, even out in the garden. Perhaps over cautious, but your liver will thank you! Cheers! Steve Rosenblum
@@PictorialPlanet I'm still working on the bottle that Jay was kind enough to send to me awhile ago. When it's done I plan to mix some up. I even have a magnetic stirrer/heater plate that I bought for next to nothing from the warehouse where our university gets rid of old lab stuff. So I'm ready to rock! The thing is I only shoot a few rolls of film per month these days (though I'm planning on cranking that up on a trip we will be taking next week), and I'm fascinated by the chemistry/alchemy aspects of film, so it's easy for me to make the mistake of continually trying out new things instead of picking one or two and really nailing the process down. I'll watch one of your videos and think "FX55! That looks cool, I'll mix some up and try that", or I'll read an old article on Thornton 2 bath and want to try that. Too much of a kid in a candy store, I guess!
Hi John, thanks for this, I purchased the book a month or two back, excellent, thank you. I was thinking of 510 for my 8x10 sheets tray developed. It was either that or PyroCat in my rotary processor. I'm still undecided, would 510 work in my Jobo ? Thanks again for the excellent work, it's really been helpful as I set up for my retirement ; )
Hi John and thanks for your comment. More thanks for purchasing my book, glad you like it! 510 is a very good developer and, according to its formulator Jay Defehr, will work well in a Jobo. I don't use rotary processing so can't help with times.
@@PictorialPlanet Thanks John, Yes, your book is literally a mine of information, all relevant ! Fantastic resource. I found a "technical data sheet' on 510 listing development times with rotary processing for most films, 6 mins for Foma 200 and 8.30 minutes for FP4, I'll start there and see how I get on. Thanks again.
The TEA in 510 provides the alkalinity when mixed with water. MPG is pretty much neutral. If your phenidone solution (in MPG) is 5% I think you'd be ok because it's such a small amount you'd add.
Great video. I read somewhere that Phenidone 0.25 g, but you use 0,375 for that part. Using more Phenidone has some advantage? How this developer compares to others, like Pyrocat? thanks
Try Kevin at Wet Plate Supplies. I bought mine donkey's years ago and can't remember where from but if you message Kevin from his website he might have some.
@@PictorialPlanet Yes, John - my first batch I bought from Germany, but after consulting with Jay, I looked for 99% TEA on eBay & found a few suppliers. But, be careful, some are selling it per kilo, rather than per litre. I bought: www.ebay.co.uk/itm/Triethanolamine-99-9-1L/393028534317?hash=item5b8253802d:i:393028534317
New Directions Aus. sell TEA (Triethanolamine). Gold Street Studios sell phenidone. eBay for Pyrogallol. Ascorbic acid powder is very common. Hope this helps you get started!
Yes, I don't think you'll miss it! By the way, don't mix up ascorbic acid with sodium ascorbate (used in FX55 for instance). 510-Pyro must have ascorbic acid to work. It's a common form of vitamin C.
@@PictorialPlanet again, thanks for the tips. I am glad I subscribed to your channel. Quite an eye opening experience with every video simply explained so latman like me can easily understand. 🙏🙏🙏
@@PictorialPlanet I want to try they all pyros... There is the fan. But it is always problematic to find all chemicals. 510 pyro at this moment in time is the one that it seems more easily achievable, but I would like to give a go to them all. Your website and videos are really gorgeous!

It is really hard to buy chemicals in small amount in Canada. I asked around in Toronto, no place that I can find all ingredients
Can you buy from the photographer's formulary in Montana?
@@PictorialPlanet I’ll check it out! Thank you! Never tried to buy anything from them
I buy at B&H as the ship to Canada cheaply.
