Vintage Ilford Perceptol 1 Quart... 70's vintage time capsule ?

[kreeger]

I opened an analog photo time capsule today for certain.

A few years ago I helped a friend sell off his father's photographic gear and darkroom items. There were old packages of paper and chemicals and a bunch of cans of vintage Dust Off from the Freon days... anyhow this little canister of Ilford Perceptol was part of the archaeology.

Shown is how it looked after I pulled the pop top off, and mixed this up in some distilled water. When it cools down tomorrow I have a roll of 120 FP4 Plus to process in it. I haven't ever used Perceptol so I am interested in what the users of it have to say:

Question 1)
Anybody have a dilution / time / temp they want to suggest, knowing the stock and dilution will be distilled water. I expose my FP4 Plus 120 at ISO 80.

Question 2)
This is how I remember things were packed in the 70s, maybe early 80s at the latest here in the US. Agree?

Attached PDF contains scan of the instructions folded neatly inside the can for your review. It shows a development time for Selochrome !

As the Perceptol is a powder developer is there any reason not to believe that it is any different from a current Perceptol developer and should not have deteriorated in any way? If it is as good as a packet of Preceptol bought yesterday and I believe there is every reason that it is then as the film is a current FP4+ there seems no reason to believe that it should not be developed according to times in the current Ilford Perceptol sheets? At stock it is 9 mins @50 and 12 @ box speed so 80 might be about 10.5

I have a nice supply of 1 Quart Ilford Microphen in white boxes. At some point the packaging switched over to the current red and white with the 1 Liter size. During one of Ilford's near death experiences I stocked up on the then current Ilford powder chemistry. The older 1 Quart stuff is fine. I credit the binary packaging for that. Somewhere I still have a few boxes of very old Agfa Atomal. It also has binary packaging but is long dead.

A few days ago, I processed the film and the results were in the range of expected density but not calibrated yet for my processes. I used it straight, and will be using that method.

So did my suggestion help or not?

It did, thanks for the knowledge. I came away with one keeper negative on this, I will post it when I make a print of it.

Perceptol is great at stock but awesome diluted 1:1. Expect some speed loss, typically one stop.
