Re: Art Boards Gesso + pumice + acorns(!)
Keith, I've used acrylic medium with pumice on yupo and on glass. I
like it on yupo but I find that it clouds the transparency of the
glass more than I like, so I've not been as happy with it on glass.
But as far as providing tooth for the gum, it works fine.

Regardless of the pigment concentration I just cannot get a decent
black. It's starting to really tick me off.
I'm totally confident that the pumice trick would work with any gesso.
Contrary to their claims, there doesn't seem to be anything
extraordinary about ArtBoard. In fact, I would imagine that pumice
added to clear acrylic medium would work as well. I bought my pumice
at a printing supply dealer.

I will look for pumice powder this weekend, in order to try it with
ordinary gesso... Have you used pumice powder with other brands of
gesso before? I'm asking this to understand if this is a combined
(ArtBoard gesso + pumice powder) or just the result of using pumice
BTW, see my latest print here:

sheets show that pattern.) Print size 7x10".
There's considerably more staining than I'd like to have, but

I started adding things to this gesso today in an effort to give it
some tooth. Equal parts gesso and ground pumice, thinned with
gave me a plaster-like surface that was very absorbent. This is a
tri-color gum on an aluminum panel:

in contrast. (The surface isn't quite as grainy as it appears here)
The pigments did not stain, which kind of surprised me after
how the surface absorbed the emulsion. I'm going to try it again
tomorrow on a similar surface sized with hardened gelatin.
Loris, you are off the hook with regards to sticking me with this
gesso. The results aren't great, but I think I might be able to
salvage something out of it.
