The dots on the top were made last night, dry now. The other five dots were made this morning.
I made the top row of dots by putting five dots of oak gall/iron ink down and then adding indigo, turmeric, rose hip, and coffee ink from right to left. The last dot on the left is oak gall/iron.
The bottom row was done in reverse, first the other inks and then the oak gall/iron on top. The middle dot is just oat gall/iron with a little more water than last night.
The indigo and turmeric inks are alcohol based inks (one straight alcohol and the other wine) while the rose hip and coffee inks are not. I am wondering if the alcohol slows down the mixing of the two inks and creates more distinct patterns? The turmeric ink dries very fast compared to the other inks.
The oak gall/iron on top of the coffee (bottom right) is interesting.
And all this means more experimentation...
