    Mercury in Photography Today

    I am aware of the problems with Mercury.
    Here is the question:
    Is Mercury used at all in any of the alternate processes.
    I am in possession of a small quantity, about 3-4 oz. liquid measure. What do I do with it?

    Why not contact your local poison control center. Also, if you have any nearby universities or colleges, they will have a waste disposal program for such materials.

    It is still used in making daguerreotypes, but that's something you don't start up casually just to use a few ounces of mercury.

    I've seen mercuric chloride in some toner recipes, but it is nothing that I've wanted to fool around with, and I've never heard of a use for straight mercury besides daguerrotypes.

    Liquid mercury is virtually useless in any photo process except Dauguerrotypes.

    As for mercury salts, it is critical to know whether you need mercurIC or mercurOUS salts as one will work and the other will not in a particular formulation. So, in the intensifier formula above, the salt is ambiguous as the ending on the word is not correct chemically.

    Right; it is mercuric chloride, of course.
