nail

In topic: I remember that during my training in OGHU, said that the best nails for this purpose, copper or brass.


But now, in the course of iron parenthesis.
(Copper is not met, interestingly, is it?)

copper is not met, wondering whether there is?

There are copper plated (clad).
A copper material itself is very soft and thin brackets from it will be deformed.

Brass nails are - yellow.

Oleg Nazarov, as you said, it is not clear. Vegetable oils are divided into drying, and malosohnuschie nesohnuschie. In painting, usually used linseed and (or) poppy oil - drying nezhelteyuschie. Due to the nature of the polymerization of linseed is considered most appropriate, it erased the industrial way paint. Paint from a tube already contains linseed oil.
That is, if someone from the original to write in sunflower (and there are such people) - it would actually be mixed with linseed and drying all the same to be fast enough. Of course, you can overwrite their own pigments to non-drying oil, so the picture does not dry out, but it's, like, why?
 Drying times are also directly dependent on temperature, and the pigments used. THEOREM some pigments to dry very slowly. In a mixture of whitewash all dries faster. Accelerate the drying temperature can be a show-now put to the battery or dried over a gas stove is when you have to, "Well, very urgently."
Usually a drying-up of detachment, a few days-week. Until the moment when the picture can put something - a month. Until the moment when we can beat them with lacquer or a year.
 Coat of paint is still at the same time remains flexible. Loses its flexibility, as I understand it, a century coat of paint.
The oil is prepared over the years is when people buy raw, non-polymerized and polymerized oil and freeze it yourself, hang out in a bottle out the window for a year or so. Then poured into the upper transparent layer. In store for artists already polymerized linseed oil-EM did not have to cook for years. It is worth it, of course, expensive.

Yes, but it's not about the nails, but the brackets for the stapler.

Suppose he pulled the canvas. Breakthroughs were formed immediately or later?

Unfortunately, I do not have this opportunity!
Yesterday went specifically to re-examine
The paint was Stone. And it's less than a year and a half!
Traces on a stretcher from the "excessive zeal" on the stretcher is not found. Something had to stay on after forceps usilinnoy stretch!
And the edge of the canvas was the width is insufficient, what would it catch spetsschiptsami. He was circumcised. Why? Stretcher initially without wedges.
  Took pictures makroobektivom fragments signature UF.Naverno understand why the signature does not beat strongly in the UV. I'm not special, but my understanding of how the signature is covered by a composition and it is partly the stack into the recesses of the canvas, resulting in the top "hit harder" in the UV and flooded deeper look at all like an old painting.

Considering the "expensive" paintings in the collection of my friend, I saw that the center is a breakthrough of the paint layer and ground (and part of the canvas), which at first glance be mistaken for craquelure. I am interested in the causes that could lead to this result. I began to examine the nails, which must withstand a load! What was my surprise when they pulled out with no effort! And the painting dates from the first quarter of the 20th century. Cap on the outside was rusty. Itself was a nail straight from the tin. Canvas not overtighten. I began to check the paint ... It does not dry out for 80 years!
Here is a story with a simple nail ....
Of course it all started with doubts about the authorship.

As you have guessed that the painting is not dry out? And if so, meaning in a conversation?

A illustrate? As the saying goes: better to see once than hear a hundred times.

Yes, I agree! Show the canvas on the back pliz.

Dries out any painting for two years in a dry place. Even craquelure will.
