HI again painters!
today my head is filled with questions!
What is the better way to use gum arabic?
I used it in washes with water, but i didn't notice difference...
Am I right if I mix it with glycerine in order to improve wet time?
thank you again and bye.

I think that glycerine is added by the manufacturer to tube water colors to keep them from drying in the tube. The old cake water colors don't have glycerine in them. As far as I know, there is no painting advantage to adding glycerine to homemade paints, and I seem to recall reading somewhere that it was not advised.

I've used gum arabic before, but never in a wash. It has been used in limited areas to added a little more shine. I've used it primarily for painting a dog's nose to give it the wet appearance. Also used a touch in the eye area of dog portrait.

You wouldn't notice the difference in washes. For smaller areas it can be used with paint mix, does give a shine to the texture, experiment by adding a few drops to a small paint mix and see the effect,

Thank you for youur replies!
I am going on experimenting, and I used a mix of a drop of gum arabic and watercolour wash in order to paint the eye of a squirrel, and it seems more expressive, as it remains a bit shiny, and I also added some drops of gum arabic in a green wash for a final touch to the foliage of a bush with shiny (is the adjective correct?)leaves.
the result wasn't bad...

I was told yeaterday that adding gum arabic to staining pigment watercolor makes them less staining. Does anybody know if it is true or something more?

I've read that it makes them less staining but haven't tried it out. Let us know if it lifts better. W&N also makes a product that aids in lifting if mixed with paint - haven't tried it either.
