How to use it ?
    * http://plantmordant.org/symplocos/wp-content/uploads/2013/07/Plant-Mordant-Project-Recipes-version-2.pdf
        * calculations made with weight of dry textile


Percentage in dye bath:
    * with tannins pigments ~20%
    * with most of natural pigments ~50% (recommendation)
<<< the more symplocos used, the less dye pigment


Water quality:
    * NO HARD/calcareous WATER !!!
    <<< use distillated water, rain water, soft water...
    --- TIP ---
        to use tap water add 0.5g cream of tartar per liter


Cellulose fibers:
    * pre-bath in castor oil ???
        #totry
    * tannin process
        "" Soak the fiber in a solution of gall nut extract 10% WOF at 60ºC (140ºF) for 60 minutes.""
        "" well suited to protecting the lightfastness of the dye""
