    According to Dick Steven's 'Making Kallitypes, A Definitive Guide' you can use the following formula

    Water - 2 quarts
    Sodium Carbonate, desicated - 1 ounce
    Oxalic Acid - 1 ounce

    He quotes Swain "this bath is most viguorous" and should clear in 10min if developed in Rochelle Salts and 20 to 30 min if developed in Sodium Acetate.

    I have never tried this myself, just reporting what I have read. If you give it a try, report back and let us know how it works.
