Re: gloy for tricolor on yupo?

I suspect gloy would work.

The casein on yupo I have done worked well. casein does not stick as hard
as egg. It was possible on one of my casein mixes to do a passive
development - without needing to brush off the colloid like on needs to
with egg/tempera.

Wonder if one could get a colloid just sticky enough to bind well to yupo,
but develop quickly with a passive soak.
