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?
