Iron Gall ink ...

I thought it time to make some Iron Gall ink ... 

... inspired by a piece of Vellum found at East Riddlesden Hall 

 Oak Galls collected on "Shick Shack Day" ... 

... equipment snaffled from daughter's chemistry set

..... Iron Gall Ink!!

... lovely antique brown achieved.

I need to refine my process in order to get black ...
