    Where can I get hold of tannic acid here in the UK? The only places I can find sell in bulk. I only need 100g for toning cyanos. :confused:

    I moved this from the "Grey Area" up to the alt-process forum. The Grey Area forum is just for hybrid digital/analog topics.

    Have a hunt around with google for on-line brewing suppliers. It is worth picking up some potassium metabisulphate too at the same time if you need to clear the dichromate out of gum prints. Failing that, use a tea bag (I prefer toning in green tea rather than black).

    Best regards,
