about Collodion (wet plate process)

[natsoon]

Hi, all

I have a few questions.
can The Collodion expired if i don't use it for 1 year or how much time?
How much of the salted collodion mixtur for one 11"*14" plate ?

[eddie]

salted collodion will work but it will be contrasty and very slow if a year old. it is best used from 5 days old till about 2 months. after that it begins toi slow and get more contrast. i have used 6 month old stuff with no problem. i have not tried a year as i use it up before that.

not sure how much you need for 1114. never measured.
