There was a program on late night BBC tv where they recreated a medievil picture preparing the canvas with Gypsum.It's one of those programs i've always regretted not recording,along with the recreation of a Medievil Banquet involving a gold leaf covered roast swan!

To whiten hide or wood with gypsum. First he gives a recipe for making glue 
with stag horn, but I guess cheese glue would work as well. Then take some 
gypsum burned in the fashion of lime....and grind it carefully on a stone 
with water. Then put it in an earthenware pot, add some glue and place it on 
the fire so that the glue melts. Stir and spread it over the hide very 
thinly with a brush. When it is dry, spread a little on more thickly; if 
necessary, spread on a third coat.
He then goes on to explain that you should polish this surface with shave 
grass until it is smooth.
He follows this with a recipe for varnish.
I know that some pigments need a specific carrier and that several discolour 
with damp and age, so all were not suitable for use.
I'll have a longer scout about for info. tomorrow.
Cheers,
Hazel
