RE: Type 55 Polaroid materials, et al..

Hi all

I've just returned from holiday and found this thread, so I thought I'd put
in my two pennyworth.

I've used Type 55 for many years and I use the following clearing and
hardening bath which I found in Ansel Adams' book 'Polaroid Land
Photography'

Potassium alum 30 grams
Sodium bisulphite 60 grams
Water to 1 litre

You can also use sodium sulphate (NOT sulphite) instead of the sodium
bisulphite.

The big advantage of this solution over the 18% sodium sulphite is that you
don't get the gunky residue left in the bottom of the tank or dish.

Hope this helps.

Derek

I have been using Type 55 for some time now, I clear
in sodium sulfite,
I dont measure my dilution I just through a couple of
table spoons in the bottom of the tank and mix it up,
The way you can tell if its finished is by waiting
untill any undeveloped areas have cleared completly,
I think i tried mixing the recomeded dilution once and
found it imposible to mix that much ss into solution.
Using perma wash is really unecessary, ss does the job
just fine, ss is also known to eat the edges of the
grain making it less aparent.
I NEVER put my 55 in fixer.......YUK!
After the ss I run it through water and then photo flo
and hang to dry. You do need to be very careful (or at
least awake) when handling them.
oh and go crazy!!YEAHHH
