Making historical oak gall ink

Some time ago I collected some oak galls because I was feeling inspired by medieval scribe culture.  I had made the graphite pen holder and was asking myself whether I was able to make myself ink that actually would work.  

I made a video on YouTube for the process and a recipe, if you so will.  

 The ink consists of the oak galls, iron oxide, acorn shells in vinegar, and I stabilized it with cherry gum as a substitute for gum arabic, which is in the original.  I also want to try out to use mistle berries (visca alba),to stabilize.  

The experiment worked well enough to be used with a fountain pen.  In the Video I also show you how to prepare a feather pen. 

Hope that you enjoy to experiment with that, and take good care!
