Dry plate.

Thank you, Julio, the problem here for this things is to translate correctly and find a place to buy in small portions and not kilos Is that fixer the fast one or the slow?

The classic one, "slow". These are really very common and ultra-cheap chemicals, you should be able to find them through their chemical formulae:

Sodium Thiosulfate ("hypo") = Na2 S2 O3 dot 5 H2O - get a kilo at least, no problem. Usually sold in plastic bags. Clear crystals, dissolve in warm water because it will cool the solution while dissolving. You could use higher concentrations that 250 g/L, up to 400, but there is no point.

Sodium Sulfite Na2 SO3 -- you can also get a kilo since this is used in a lot of solutions. A favorite of mine is hypo clearing, with 20 g/L. 15 g/L is enough for fixer.

These concentrations are not critical, you can vary them about 20% and none the wiser. No need for high precision weight measure.

If you can get a line on a photo club, or the chemical lab of a university, they should know where to find these. I assume that there are no yellow pages in Moscow?

I found several places already, the problem is the quantity I need is way lower than minimum order, they are internet-shops, no place to go and get the order.
Another is start making all the chems myself... at least D-76 and let's see if I can cover the minimum

New plates from 1958, only 12 and one is gone, good this I found out the ASA and develop time at first try
Rated ASA 2 (it should be around 5-10 originally) and 4min. with D-76 1+1 at 20C.


Weekend rituals.

Several dark spots here and there and less sensitive at borders, inner emulsion is ok.
In the box says "Halftone Reproduction", I'm not an expert but is it panchromatic? Colours at photo are white background, wood table top and golden the grinder.

Thank you for looking,
Alex
