    Has anyone used, or know about, methyl cellulose as a sizing solution for gum bichromate? Are there any long term detrimental effects on the paper with methyl cellulose?

    I want to make some gums over the weekend and have no gelatine. I coated a few sheets of Bergger COT with a dilute solution of methyl cellulose and some formalin added just prior to coating. The paper is now dry and there seems to be no yellowing.

    Have searched the archives but can't find any information about sizing with methyl cellulose.

    Methyl cellulose was recommended to me as an adhesive for "T-hinging" watercolor paintings on paper when mounting and framing. As I understand it, it is acid free, archival and reversible for such use. The fact that it's reversible presumably means it's water soluble. So it should be fine for paper, but I have no idea about the gum dichromate part.

    Thank you all.

    I hope to put the sizing to the test over the weekend. Will upload images if the prints are acceptable.
