hi Yloo.  I make my own ink.  This is some that I made with iron, hydrochloric acid and lye.

Ok... I found my answer in your other picture "Physarum dyed with red iron oxide, in a salty magnetite ink circle, showing interest in valerian root". Now I have an other question: Do you make the magnetite ink circle with a black felt pen or something else? Where do you buy it, do you have the brand? Thanks a lot :-)
