Default Liquid emulsion

I am not sure if liquid emulsion counts as an 'alternative' process but anyway I am thinking of having a go, having been inspired by some prints in the latest issue of LENSWORK.

The question I have is a practical one. How long does it usually take for the coated paper to dry? I forsee a problem whereby I have coated several sheets but cannot leave the darkroom (which is in an outside garage) until they are dry enough to put in a paper safe. I guess the answer is to do the coating at night but I wonder if anyone has dealt with this before.

I got around this problem by putting the coated paper in old paper boxes, one sheet per box, and then leaving them overnight to dry.

Dave’s suggestion is a good one, as you need the air space above the coated sheet while it is still wet. After putting it in the box, put a black over the box to ensure light tightness.

It is clear that the contributors above have had actual experience so rely on this to a greater extent than what I am going to say but Lee Frost covers this in his latest(last?) analogue book. His caveat is that he found there was a tendency for the tops of his boxes to be drawn down to the paper due to the wetness of the coating.

His recommendation was to put cardboard stiffeners in each corner. I think he was using old photo paper boxes.

Ilford boxes are particularly robust so this may be an unnecessary precaution. Worth knowing about though in case it arises.

I'd say more about exactly what he did but it was a book borrowed from the library and I no longer have it.

I normally coat 10/12 14x11 sheets at a time last thing at night.
After coating put them in a light proofed filling cabinet secured by two small bulldog clips to the file hangers with about 50mm gaps between.
Transfer them to a box after drying overnight. Works well for me.

Depends on how many sheets you want to do at a time and what you want to spend but a couple of 10x8 paper safes would work ideally I'd have thought for drying then transfer to paper boxes.

The Jessops type come up on e-bay quite often and aren't expensive - well not compared to the long term cost of using liquid emulsions.

Being plastic I don't think they would work too well, I think the cardboard box works by absorbing the moisture from the emulsion; having said that someone will now say that they have been using plastic boxes for this job for years.

I've been coating sheets of glass with a liquid emulsion - To dry, I place them in a Jessops style paper safe or a largish paper box along with a pot of silica gel (or other water absorbant granuals). The plates are usually dry after a day or three, although the ones in the paper safe take longer to dry.

Thanks for those excellent suggestions. It may be a while before I get around to trying this- I have a backlog of 'straight' prints to do- but it looks like a good Autumn project.

Paul, sounds interesting and wondered if you are printing neg or pos onto the glass. If neg and backed up with black backing, would they look a bit like an ambrotype?
