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

On Monday, a special call and ask: what chemicals (formula) they contain cadmium?
Correctly worded question?

[Seriy]

NATA NOVA, can not call, I've read, no cadmium. Yes, and all the rest is questionable, chromium, cobalt. We Daler-Rhone, too solid synthetics. I tell you, an oil painting classical come to an end, will remain one name. Then and butter substitute.
Maybe that's for the better - and then the entire Periodic Table palette.

That is, their pigments are mainly siteticheskie-analogues? (imitation?)
And those cadmium, that I (Podolsky and leningradskiesovetskie)-natural and poisonous?

[Seriy]

Yes, natural, very persistent and terribly toxic. But Matisse's fish are still bright :-)
Incidentally, I'm going to Podolsk, I paint finish, and they have some of his land, ocher unique-curious, and kind of cheap-but I have to train a lot.

I restorer about their land (Podolsk) has an effect that is very good and do not change completely .. Many take it (good and different!)

[Seriy]

I am very fond of ocher - luxurious colors.
By the way, Podolsk generally done without a table lightfastness. Written-all excellent and very lightfast! to help people get their brains are not sacrificed.

Think. So it is .. Until now, such as willows did not occur for lightfastness sdelit, there was no reason ... (it may now appear ..)

NATA NOVA!!! Natural yellow strontia CAN NOT be persistent! Podolsky it or from the most naikruteyshey company.
And you can not follow-it of decades at least.

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?

The answer to all your questions - In the chapter "The darkening, yellowing and other changes of tone in the oil painting" in the book Kiplika, kotoruya I said. How to fix there too. Very detailed explanation. Based on this book is not outdated.
