So what is your problem.
     

Thanks, but that tone rather harakteten for claims, and not to help. Do not you worry about us. Premnogo grateful ...

Pavel, you have a non-standard methods, it is unclear where taken.
The fact that the PVA has sharply alkaline reaction, T e is the alkali, and many colors can enter with him into the reaction with unpredictable results. Nobody knows when and what, therefore, the standard grounds in its neutral acid-base reaction, rather than alkaline or acidic.

K-Maler, is the use of special literature zero. I Kiplika Nate or I would send something from memory?
First, many pigments, the materials described in Kiplika, currently out of use.
Secondly, you said Svarog, 1998, but he Kiplik, original - this train early 20 century! And relevant scientific expedition .. Cartage, shorter .. That is not clear what he says and what, on what basis his findings, on what Dmitry I. so did the glue from sturgeon cartilage Astrakhan in 1856 and bequeathed to us?
Third, firms making paints, usually conceal chemical composition and origin of the pigments in the paint. Type-trust us! I talked to, for example, with the laboratory GAMMA - pleasant people, but they are no secrets you will not open. That is, probably, all manufacturers of the same pigment with Bayer Chemicals, only some have enough conscience write-malostoyky, others have the courage-srednestoyky. You understand that the factory paint itself does not produce pigments, they produce himkontserny.
V-quarter, though we all believe in words. What do I do next? There is a huge list of colors that are either srednestoyki or unstable. Some of them, for example, indigo, vandik, strontia yellow made from the time of King peas. Ultramarine, krapplak, turquoise, Lazorevaya is all medium or small-resistant pigments. So what to do? not use them? and what to write? - ocher, white, bone burning, cobalt-cadmium. Sadly turns ...

So neither from science nor from trade assistance and advice there. Why can not make persistent pigment? probably is impossible. Even car paints fade, although there all the power of Chemical Industry. And what new items-resistant acrylic? Who can guarantee that?

The paper is not sent out (probably just thought ..)

Very interesting, thanks for the experience. Paints a surprising number. All did not pereprobuesh.
Paul then said that if you do not wait until fully dry (a dry white for decades), then two weeks later something is black. I do not have such experience, often without waiting for 100%dry, some pictures for many years, but did not darken. What experiences have others?

[Seriy]

Konstantin, a lot of paint in tubes, and pigments - one, two, and all. Here white? two-zinc, titanium, lead, left, barium released. Black-carbon (bone burning, bone burning, soot, gases), Mars Black, t e a kind of iron oxide. So for the rest.

Here's what's the difference with butter .. Some written many hundreds of years ago, look like a bud yesterday zakonchennynye ... And some (recent, as a look), then withered, then black, then cracking, then sprinkled with ...

From my experience, I like the safety alla-prima on a simple good carpenter glue ..
About whitewash Pavlovsky not have the experience ..

At the exhibition in the garage of the collection Pinot been working oil - portraits of priests of various concessions, completely withered. Probably written in very dry soil or no. So that did not have to wait for centuries.
IMHO, soil, withdrawing oil from the paint, nothing good painting will bring. At all times, ready ground still held Llano oil, so it is not pulled. If the oil paint from the pull-cure that then?

Seriy, in the picture spigmentami (where only a part)
top row (white): titanium white, zink white, blank fixe, rowdered marble, lithopone, alumnia white
(the last four, never used and do not know)

[Konstantin]

And about the different layers and desiccation as a result of the darkening that say? Faced with such?
