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.

http://www.dickblick.com/items/00495...#colorpigments - here you can get detailed information about the components.

Ninni,
Thank you, very interesting link!
Yes, to this conclusion we have come - Van Dick and other pigments, suddenly became very persistent in sovr manufacturers now simply made up of other pigments in like the original Dick Van flavor. As you yourself can do on his palette.

Original Van Dick - Brown is a natural earthen paint.

For your reference compounds of concern such as color pink - honestly write-not for external use (r e unstable) or GOST malosrednestoyky, but in our tests, it is nothing.
Êàî-no miracles, we must accept the fact that some of Kohler can be very persistent, such as iron oxides.

It is a pity that the theme name! On the second page, I specifically asked about the canvases. Results per person! We see that there is a huge number of techniques, tricks, secrets, etc. And of course everyone believes that - it affects the quality of the painting. Now the question: Does the art historian to know about it, and if he does not know approaches, whether it is a good art critic? Pavel, do you think?

Artem! Iskusstvovevy shall not engage in techniques and technology. This is a question of preservation. But often, stretch, technique and other details suggest a level of skill of the author. The easier and more professional than the usual run the wizard and it does not raise questions about the canvases and tezhnike, all in-date information.

Pavel, the quality of stretching the canvas or the technical performance of the work has nothing to do with the level of the artist. Leonardo all crumbled and cracked, but that he does not cease to be by Leonardo.

Thank you, dear!

These are (jointly) have discovered a very important (in my opinion) is reliable information:

PR108-Cadmium Red
Pigment Type
inorganic, cadmium

Chemical Name
cadmium sulfide and cadmium selenide

Chemical Formula
CdS × CdSe

Properties
Cadmium Red is a bright, warm red that ranges in shade from orange-red to maroon and is available in light, medium, and dark versions. It is strong and opaque, with good tinting strength. Cadmium Red dries slowly. It grays down when mixed with white, mixes well with blues to create a range of browns, and mixes well with Cadmium Yellow to create a strong orange. It also works well in neutral mixes. Cadmium pigments have been partially replaced by azo pigments, which are similar in lightfastness to the cadmium colors, cheaper, and non-toxic. Hues vary by brand.

Cadmium Red is usually available in either a pure grade or a cadmium-barium mix. The cadmium-barium mix has the same permanence as pure Cadmium Red, but it has a lower tinting strength.

Permanence
Cadmium Red is lightfast and permanent in most forms, but like many cadmium pigments, it will fade in fresco or mural painting. Its improved lightfastness has helped it to replace Vermilion on the artist's palette.

Toxicity
Cadmium Red is a known human carcinogen. It is extremely toxic if inhaled and slightly toxic if ingested.
History
Cadmiums get their names from the Latin word cadmia meaning zinc ore calamine, and the Greek word kadmeia, meaning Cadmean earth, first found near Thebes, the city founded by the Phoenician prince Cadmus. Metallic cadmium was discovered in 1817 by Friedrich Strohmeyer, but Cadmium Red was not introduced until 1907 in Germany.

Alternate Names
Cadmium Scarlet, Selenium Red.
------------
translation:
Toxicity
Cadmium Red is known as kantsirogen. It is extremely toxic if inhaled and is easy to toxic by ingestion of food tract.

What are you going to fill them potatoes?

NATA NOVA, and in trace amounts-millionth of a gram, and .. alas ... And not only cadmium red, there are other cadmium pigments-all carcinogens terrible.
Nata, and soot, gas and burning bone-also carcinogens.
And hexavalent chromium (yellow) is bad, and cobalt is also not a gift ...
Lead highly toxic, and mercury (cinnabar) ..
And with the removal of the pencil turns into carbon dust and gets into the lungs. A colored pencils-story building in general kranty.
That this is, painting ...
