The ones below will allow us to determine the composition of various valleys, depending on their use. Verians of painting. Their role during the execution of painting is to enrich the paste in the paste, to make them fluids, more transparent and deeper, and finally to rush their socket. There is no scene to be reversible because it is definitively applied as parts of the painting itself. The only Sicalive oils used is ricin; He enters the doses of the lamb in the composition of alcohol verrics in which it is soluble as it is cruel. Certain hot treatments turn it into a sicative oil that some have tried to combine it with colors; Thus, he changed he is drifting quickly, without getting yellowed, but he gives birth to viscous pasta. From all time, amber or copal wins were based on in, oil that brudeting very hard, but it is in depth, which gives it a high resistance to solvents and empRIs.
It is not the case with Mac oil and old similar products (NUCA) or modern (soybean, wild soy), whose single merit is that a little colored, while using them in painting causes many accidents. This role can not be held: neither the only essence that, involving the color oil infrastructure, would dry them, would make them lose adhesion and sonority. Neither oil, alone or diluted with the essence, because of the slow pace of drying, execution; In addition, there is a risk. Migration, brunisaries and mediocre imbaths. Neither the single resin, because its permanent sensitivity to solvents would be overlapping, in addition, would be dismissed, even in the presence of a conditioner. It would repeat the accidents caused. In the nineteenth century of the excess of Terebentine by Venice.
But these three components can combine (and even in quite different ways) to prevail particularly quality, particularly demanded. There are, therefore, many painting vernies, which differ not only through their oil content that can be boiled or raw, but also through the resins used. We will divide them into two categories. Colorless painting vernies at, whose use has begun relatively recently, although in the classic era, similar horics have been made for other purposes. They contain an essence that we choose to be more or less severe. Depending on the desired duration, a sicifier (Mac or Standolie) and a proportion of a soft resin (a ketone resin is preferred today to Damar). They are easy, which is why they agree and beginners.
Diluted, in need, with the essence, they are used as liquids forced and washed brushes. Colorless as water, will not be closed in color than because of the included oil. It is more possible to confer gloss than to shape, a certain fragility could be reproached and the fact that they are hard. Dealt, it is indicated a slight "sicivation" of some of them. In order to offer a more accurate idea, we will add, among other things, Viberl painting vernium, the lefranc-bourgeois colorful painting medium and distinctly through drying speed, three tens, well-known: Rembrandt, retarded and fast painting . Boiled oil at high temperature and in the inert gas atmosphere; Qualities: Salivital high, density, shine, water resistance. Veries with hard resins (whose type is known Verniu with amber), become amazingly resistant to solvents, as well as aging.
They point the enthusiasm of Mariinee, shared by Xavier by Langlais. Once, the development of the process of their manufacture has determined the long-term Research of the Doctor of Mayerne. The result of the caid processing of the fossil cops, they are therefore colored, and the fact that they are rich in oil (ingam-binding) is not favorable to open or cold tones. In addition, sometimes some colors. They are minor inconveniences, but who knows how to use them properly. Continuing, often, lead, they favor in-depth drying, give the painting a lasted aspect and ensure a good preservation. We will not come back here on mediums (Flemish or Venetian) because we have studied them on the hand.
Despite some profound compositional differences and their advantages, they join the painting vernies, through their role, and by the fact that, as we worked, mix with the colors. To be complete, we mention the wax; In admixture with boiled oil (Venetian Medium), it is a painting vernium offering ductile and poor glow.
