Hey guys,
I have asked one of the experts, Manuel, and am awaiting his reply but I thought I would put it here to see if any others have experienced this problem.
Any way, I have been stripping green industrial X-Ray film in a sodium thiosulfate solution to the point of saturation.
The next step is adding HCl to convert the suspended silver to silver chloride.
Now I add iron (nails) to convert the silver chloride to silver metal ( grey concrete color).
I then (after it has all converted) I do several HCl washes, to get rid of the iron.
Next I do many boiling water rinses. Then I put it in the oven to dry it.
Okay, so far, all is going as planned.
When I pull it out of the oven, it has turned black. When you try and melt it, it smokes and smells bad. Also, the melted silver is really ugly, and has a thick black layer that is hard to get rid of.
It is Lazer Steve's, and my thoughts that this is the protein emulsion from the film.
Does anyone know how to get rid of this emulsion so it doesn't cause these problems?
Thanks to all !!!
Kerry
