of which ethylene and Propylene glycols are relatively simple members.
Gluten is a nitrogenous derivative of both plant and animal substances.
My concern is about Propylene and Ethylene are which are commonly =

Dear Corbus,
I suggest you do some trials with your own materials, starting with a =
one percent solution in water, working upwards until you get smooth flow =
from your brush. I think the optimum will be below five percent. I use =
Gum Acacia as a siccative which is made strong enough to make my fingers =
seem to want to stick together then put in a few drops of glycerine. =
This slows the drying and leaves a smooth brushstroke.
Have fun with your experiments.
Best regards,
Ivor
