Drew, PMT is short for Phenyl Mercapto Tetrazole. The whole point is it isn’t Benzotriazole (which does pretty much nothing as far as image colour is concerned) although it is related.

Michael - Benz restrainer (vs KBr) DOES typically print shift image color cooler. This has been known for a very long time, and I've personally experimentally known about it for decades in relation to my own work with multiple papers. The proof is easily visible. But like I already mentioned, that relationship can reverse or invert when gold toning is involved afterwards.
Interneg - Yes, monohydrate. That's what typically used for the formulation. I don't know about early literature. Mono is more readily available here.
I think “…known for a very long time,…” is the key phrase. A hundred years ago, maybe.Originally Posted by Drew Wiley
Just as true today as back then. If I mixed up with and without solutions ten minutes from now and printed the same image using each respective developer, it would still be a valid statement. Besides, we're talking about Cooltone paper in particular here, which hasn't been around all that long. I've tested all kinds of developer tweaks with it, including 130 formulas using different restrainers, along with mixed amounts of the two in question (benz vs Kbr).
Nice try, however. Maybe you'll land a fish next time.
You should really have one of them YouTube channels.
I might watch U Tube if you tell me how to link onto your Fishing tutorials. I think you need better bait.
I’m telling you, you’d have the best YouTube photography channel by a country mile, and you’d be a YouTube star.
Zzzzzzz .... snore .... zzzz.
