Ilia, have you heard of "ashgrove kemilime", chemical hydrated lime? If you go to their website and check the chemical compounds, it seems ok.(ashgrove.com)
I had to pay 50 dollars for a bag of 50 pounds last time, the lime works fine for fresco,(the telephone number I gave you last time), but the price seems a little high, even if you take in consideration the cocts of shipping here in hawaii.
The lime from ashgrove is only 15 bucks for the same quantity. How can you tell the difference? What would be the criterias to differenciate?
I did my own bianco de san giovanni, 8 days stirring and changing water, drying in the sun, crushing the powder. When I apply it to my painting it seems a little weak, how many layers of bianco would you use to come out with a perfect white?
I have access here to the work of Jean Charlot, I can take close ups of his work, all sorts of pictures. Do you think it might be interesting for your site?
Tell me if you need some picture data from him.
Thanks for your your help.
Mathieu
