MGFB, how to determine age?

[Thomas Bertilsson]

Peter, I only just found out about this formula myself. I'll post a recipe here as soon as I can find it.

Here's a case where I wish Ilford would take a page out of Kodak's manual and print dates on the box. Would make things alot easier. Luckily though, Ilford warmtone is one of the best papers out there IMO so I always used it up well before it got to that point!

Sorry for crashing this thread, but who knows how to find the use by date of Ektalure. I've got some 16x20 boxes which I think are from the last run and the serial number is 42401-001DQR 66, though can't see a seperate date on the box. I'm sure when I was using a lot of Ektalure in the early 90s the label always had a date. May well put them up for sale but better find out how old they are. (Probably 8 or 9 years.)
Many thanks
Mike

I will check the dates and come back to you

The only Defender developer I found so far is this. Hope this helps.

Dupont Defender D-55
Gives good warm tones on Ilford Multigrade Warm Tone and Forte Polywarmtone papers. Use this diluted 1:2 with water. This is a very economical developer.

Water 750 ml
Metol 2.5 grams
Sodium Sulfite 37.5 grams
Hydroquinone 10.0 grams
Sodium Carbonate 37.5 grams
Potassium Bromide 13.0 grams
Water to 1000 ml

Dear All,

Batch 64 D October 2001
11 B May 1997
15 E September 1997
27 E September 1998

Since people are discussing older product, I guess these are the manufacturing dates but
apart from 64D we have used those codes again

11 B August 05
15 E December 05
27 E December 06

Regarding the longevity of paper product, I have referred to this before, its all about storage : kept cool in a dry dark storage area without large temperature variations it can be usable for many years, I have used paper well over 10 years old before, the stability of modern emulsions are excellent from all the major manufacturers. As always its base fog levels that increase and a simple test should establish if the paper remains usable.

Regards

Simon.

That's very useful information for me and it certainly looks as though the paper will be worth trying out. I'll come back in a couple of weeks and let folks know how I got on.

I've never tried mixing my own chemicals, but it is something I've thought about in the past and maybe I'll have a go at this dev.

Many thanks again, Peter

Edit: I've also just found the formula for Defender D-56 on here at http://www.apug.org/forums/forum222/...nder-56-d.html
