CHOOSE A CANVAS FOR PAINTING
I, as a restorer, are categorically against self-gluing and priming by the artist as a canvas. I hope it’s not worth explaining why. However, if you are still sure (I emphasize, sure! Most of my clients thought that they were sure) in their formulas and hands, then I will answer the two most asked questions: which uncoated canvases are the best and the better to glue an uncoated canvas.
Unprimed canvas needs to be bought exceptionally dense and without knots. Rare nodal canvases do not last long, even despite their high-quality gluing and primer.
Surprisingly, many classics of the still Soviet painting technique in their works of half a century relevance repeatedly mentioned this circumstance, however, our classical school stubbornly does not want to see the problem, reducing its solution to a greater application of glue and soil to the canvas, which is categorically incorrect and does not solve the problem of strength painting.
If you prefer uncoated canvases, you probably should have heard about Belgian flax. If you have not heard about it until now, then I assure you that you don’t know anything about uncoated canvases and you will have to cut their world anew.
So, there is no list of the best uncoated canvases. He is the only one – this is a canvas from Belgian linen.
Why is that? Because only Belgian flax in its raw (rough) form, namely as a type of flax, is best suited for subsequent manual gluing and priming. Due to its excellent raw data, it does not require any additional processing. This is the cleanest natural eco-friendly linen for painting.
In principle, Belgian flax can be purchased directly from Belgian producers, as well as from many European producers. Belgian flax is used to make the lion’s share of all European textiles. Almost all Italian, French and Dutch manufacturers use just Belgian flax in their production.
CHOOSE A PRIMED CANVAS
It amazes me that so far on the Internet there is practically nothing about what our beloved native Russian artist writes on. So, we will talk about Russian domestic canvases, or rather, what they really are. I must say right away that I will not be engaged in an analysis of each producer and I will start once with a sentence – without exception, all Russian canvases (including Belarus) are categorically unsuitable for professional painting!
To begin with, let’s figure out what is a poor-quality canvas in terms of durability of painting?
A poor-quality canvas is a canvas that has a large number of knots, has loose (loose) weaving, has an inhomogeneous (prickly, brittle) surface, has undergone chemical treatment (I will not consider it here). It is enough to have at least one of the aforementioned shortcomings to safely refer the canvas to poor quality.
LET’S DISCUSSE EVERY DEFICIENCY SEPARATELY.
Nodules are places of fastening of the so-called thin short thread (should not be with hooks). Nodules are the most visible indicator of poor-quality canvas. You can’t hide them. Not only is it simply uncomfortable to write behind a knotted canvas, but you also have to cut the nodules and in the places of cutting the thread becomes completely unfastened.
What is the danger of nodules on canvas? Nodules are the most vulnerable part of the thread of the canvas, it is in the places of the nodules that all the processes of canvas decay begin.
Canvas leakage is the result of weaving technique and depends on the technological capabilities of the manufacturer. The density of the canvas is the main characteristic of its quality and is measured in g / m2 (weight of 1 square meter of canvas, expressed in grams). The denser the weaving of the canvas, the more qualitative it will last longer.
As a general rule, the higher the density of the canvas, the larger its grain. A fine-grained canvas has a lower density, a medium-grained canvas has an average density, and a coarse-grained canvas, respectively, has the highest fully. However, one should not assume that a fine-grained canvas with a density of 250 g / m2 is worse in quality than a coarse-grained canvas with a density of 500 g / m2. There is also such a thing as the thickness of the thread itself, which affects the overall density of the fabric. Naturally, for fine grain the thickness of the thread will be less than for coarse-grained canvas. Therefore, for each type of grain of the canvas there is a sufficient density.
For linen canvas, the density of fine grain should be 200-300 g / m2, the density of medium grain is 300-400 g / m2, the density of coarse grain is 500-600 g / m2 The upper limit of the density can be higher than the specified ranges, but not less . If the density for the indicated type of grain is lower by at least 50 g / m2, this is an occasion to think about the quality of the canvas.
However, from the above standards, there are still popular exceptions. For example, some coarse-grained canvases have a density of 300-400 g / m2, which corresponds to the level of medium-grained canvas.
