About the darkening will not say anything.

Why? Positioned themselves as restorers should tell us about the darkening ... (I think so ...) We will be very interesting opinion of the expert (professional) ..

Hemp yarn greatly increased in volume with exposure to moisture, so that a canvas will be seriously distorted by changes humidity. This consequently affects the preservation of paintings.
About the difference between hemp and cannabis know that hemp moisture swell even more.
Various layers of drying time to change the tone of the pigment can not influence. Does the number of layers and many other conditions.
About craquelure can only say that it is necessary to change the solvents kazhogo layer and the drying temperature. This is my "know how", the result of experiments and just random errors, sorry, the details of the method can not describe.

Have in mind when pigments are beginning to migrate? For example from the lower podmalevka, provided that it is dark?

The migration of pigments, as I understand it - is the diffusion that occurs only later during the life of the painting.
I was due to effects on pigments, light and composition of air.

Marina13, but what can you say about the pigments with one star, T e malosvetostoykie ... Among them are very important, for example, VanDik ... Can they write, and if not, what to write and why did they produce?

Konstantin, Rembrant wrote on the slate soils, t e covered with soot and nothing, nothing anywhere not migrated, and then we'd have long had a place of Rembrandt pure black squares and rectangles.

Pavel, but what the Soviet sketch paint? were in the banks and not pure pigments, a mixture of straight, so do not mix?

And my Van Dick, with three asterisks
Releasing them in order to enrich and expand our palette of possibilities.
If you expect that your work will look in museums for centuries use pigments with three asterisks

[Seriy]

Marina13, and as such can be? because if pigment is unstable, it is connected with its chemical nature, if you change it himprirodu, it is another connection and another pigment. Not explain how you understand it? or all strontia yellow unstable, and some producer has three stars on the same pigment .... a miracle of marketing?
We looked Multi base producers, some VanDik less stable, others more, and Schminke puts all high resistance. They are highly resistant and lemon. Riddles ... most likely a new dyes, made under the usual color of concrete.

Yes, it is. I dropped into your own site Schminke

and read that their academic series of 48 color DOES NOT CONTAIN CADMIUM! although the names of solid cadmium. So it's all Synthetics!
