Re: Anthotypes



 liz, a mordant is a chemical that combines with the dye molucule and the substrate molecule that  produces a fixed color so im wondering, since anthrotype relies on uv bleaching if the mordant should be used after the print is finished. in this instance, the mordant would be used as a fixer for the print. the mordant can also change the color of the natural dye. the most common mordants are alum, tannin, iron, tin, copper and chrome (from less toxic to more toxic) . one alum that is sold in garden centers is aluminum sulfate. iron saddens or dulls the color, tin brightens the color, the alums tend to just fix the color and leaves it as it is, tannins darken the color also. natural dying is a science into itself and theres a lot you can do with it. i did anthrotypes with my students one semester and it was a blast..... and where in maine do you live??   peg
