Albumen Print - image disappearing in fixer
I'm having a problem with my albumen printing and hope someone can provide some insight.
My salt printing is OK as is my albumen printing using Matte Albumen paper as described by in Christopher James book under the Zoe Zimmerman Matte Albumen method.
I'm trying to get glossy albumen prints and can make double coated albumen prints using Mike Robinson's method. The image looks OK after UV exposure and survives the salt/citric acid baths and washes. But as soon as I add the fixer, the image largely disappears.
I use the same fixer for salt and Matte albumen with no bother at all. It is as described in the books (100g/litre sodium thiosulphate with 2g/litre sodium carbonate; 2 washes each of 4 minutes).
In making the albumen paper I harden with isopropyl alcohol/ammonium chloride between albumen coats. I even harden the second coat to make it easier to coat the silver solution with a rod.
I'd be grateful for any thoughts as to why the image is being so massively affected in the fixer bath.
