510-Pyro

I found this recipe on another site and really like it.

Just add chemicals in order and then heat to about 150F stirring to dissolve the chemicals.

It works as a one solution staining developer. Use it like HC-110, measure, add to water and go.

I use it with 400 Tri-x 120 at 1:200 @70 degrees for 12 minutes.
HP5 in 4x5 I use 1:100 for 6.5 minutes @ 70 degrees.

Jay has come up with a nice staining developer that was easy for me to use as I didn't have to change procedures from the HC-110 I've used before.

I understand this developer has a very long shelf life, but I've only been using it about two months.

If you don't want to buy bulk chemicals, Artcraft sells a kit. That's how I used it the first time.

I've been using a water rinse and TF-4 fixer

I think it's only a matter of time before this developer replaces all other staining developers for a majority of users. To know it is to love it. What it does for Plus-X has to be seen to be believed.

I've tested 510-Pyro and I strongly prefer Pyrocat-MC.

I'm not here to argue, or advocate. I respect your preference, though I don't share it, and I believe it will eventually place you in the minority.

Tom Hoskinson · 11-16-2006, 05:00 PM

I'm not arguing or advocating, just stating my personal preference, based on my comparative testing of several staining developers - and I have more developers to test.

Understood, and I wasn't accusing you of either. If you don't mind saying, what was it in your comparisons that won you over to Pyrocat? I could find nothing to win my heart away from 510 in any of the pyrocatechin developers I've tried.

Did I offend?

What is TEA?

Tom Hoskinson · 11-28-2006, 05:37 PM

TEA is Triethanolamine. It is used as a developing reagent solvent. Tea is also a source of alkali when water is added.

510 Pyro has a consistency like HC110.
