ilia,
i tried the lime, works ok for now, i try to prepare my mix of sand/lime/crushed volcanic rocks a week or two in advance, to get a maximum of plasticity when I use it.
I called the chemist from ashgrove, he told me their lime is fine for fresco, that the quality now is much better than during the renaissance. I don't know what to believe, i just use it, I'll see later.
I'll soon get a digital camera, I'll be able to send pictures from my work+pictures from jean charlot's work.
Do you use only terra verde for undertones? Can you use all sorts of cold color, like the blues, violet?
If only terra verde can be used ,how do you insist between a zone of moderate shade and a zone of very dark shade? Do you double the layer of terra verde?
About the amount of layers you can use for coloring, can you only use 2 layers of ocres? What does happen if you use more? You "plug" your plaster? You loose the luminosity of the plaster?
My paintings are sometimes well balanced in tones and luminous, sometimes "plugged" and stern.
Easy to loose your cold blood using that technique...It is also very satisfying, it has a sort a magy that oil doesn't have.
I should have some picture data next time I talk to you.
Mathieu.
