Linen canvas is not as susceptible to the time istlevaniyu framework of cotton, more durable, and does not miss sizing and primer on the contrary, when properly primed. The rest, as a primer gives. Another important factor is the proper care and storage of pictures of writing on a particular material, since no proper storage best material fails.

FLAX basis.

The most common basis for the painting is the canvas, which is closely associated with the chemistry of oil paints. Linen canvas is made from plant fibers-Linum usitatissimum. Canvas is durable and textured material. Rough and uneven tissue is a major factor in the choice of this basis for painting.

A diverse selection of linen textures differ in the number of threads per inch:

- The average invoice (contains 79 threads per inch);

- Smooth texture for portrait quality (contains 90 threads and more).

Linen canvas is a single (SW) and double (DW) weave. Double weave is much heavier, denser and more expensive and is used for a single large-scale paintings.

"... strength of flax yarn to break 2 times higher cotton and 3 - wool ... the remarkable properties of the material added to its ability to increase the strength of high humidity, although to a certain extent ..." ( Len Czarnocki LP in history. - In the journal. "Questions Ithor ." 1982 . № ​​3. P.84 -90).

SW. iosif!
And what does the type of canvas to spending the gallery?
Do you compensate artists operating costs? :eek:>
Yes this is gummanizm! :)>
Well, I bought them linen, do not hurt poor things! :p>

Sergei, that's the thing that will compensate, and completely.
And always buy linen that much more expensive cotton.
Until you have a question - why?
Not in terms of compensation, but in the sense of the overpayment.
We're breaking canvases do not feel ...

kozhinart, wondering when it starts "istlevanie of time"?
Especially under normal storage conditions (even under abnormal rot steel :)>)

SW. iosif!
It is sad to think that artists, for which you try,
You could not answer such a simple question.
Strange and read thread where artists discuss the question
in the sections of "life", "prestige", "status", "tradition", etc.
From the discussion of the case applies only to (partially) granularity.

The answer is simple, and is connected directly to the painting.

Paint brush goes to the canvas.
To describe the process traditionally used the verb "goes".
Used idioms (?) "Goes hand", "goes on the canvas."
Examples: "With this brush paint easily comes off," "On this canvas paint comes off easily (tight), thick (thin)".

For some reason the "delicious" paint goes only hemp and linen canvas types
(Well, what else can on the exotic, which I did not use).
But the grain - a few changes these pleasant.
 With cotton canvas (and the "tent") - feel completely "wrong."
The difference - how to kiss prostozhenschinoy, and with his beloved \\\\ beautiful \\\\ desirable woman.
(Although it is possible that there is somewhere in this cotton canvas weave that allow ... " But I do not allow, Petrick " (C)).

If the artist did not feel it, then I guess it does not matter.
Ask them a good portion of cotton.

Sergey burly, with this interpretation has never faced.
Must hold a mini survey.
You got me intrigued.
Thank you.

In addition to the strength of the so-called important samonatyag canvas with adhesive primer, primer surface after treatment with alum.
There samonatyag - will be painting in the presentation , no - sag bubbles even in the process of writing and no wedging subframe does not help. A samonatyag depends on synthetic additives .

I wonder now whether there is someone who handles canvases alum and all, how many people have seen these alum really in the eye?
:)>

Yes, the process, especially if studied painting techniques.
In describing the techniques of painting even said why do it in more detail.

I also know about the alum, read.

But you know that this is how the base using alum and, most importantly, where to buy them?
