Health problems with cyanotypies on clothes???

  1. Hi folks,
    anybody got experiences with cyanotypies on clothes?
    Any risks for your health known? (What is washed out during fixing,
    what stays?)
    Also, any experiences about long term stability (T-Shirts are to be
    washed sometimes...)?
    Talking about the "new" one-component-process.
    Thanks,
    Martin
     
  2. Both cyanotypes processes produce the same pigment, Prussian Blue, which was widely used in the textile industry for the last 200 years or more. Prussian Blue was more or less supplanted by a new product in the 1970's, but it remains a safe pigment.

    I'm not sure how long a cyanotype imprinted on textile will last, however; dyes and pigments are usually fixed in textiles with alum or similar products to make them more permanent. Also, soap is a mild alkali and cyanotypes tend to discolor in such envitonments. Washing in pure water or with very mild soap only would help.
