Oil and oil painting thinners

Oil painting can be used to dilute oil paint, on which it was grated, found in the raw or cooked state.
However, beware of excess oily oils, as this causes wrinkling of the paint layer and its cracking.
The best thinners are agents that, having served their purpose, volatilize.
Volatile mineral oils or balsamic turpentine perform this task well.
Volatile mineral oils are obtained by distilling kerosene.
They are:

• petroleum ether,
• gasoline,
• gasoline,
• ligroinitp.

They have a low specific gravity and consist mainly of chemically inactive hydrocarbons.
They are excellent diluents, as long as they do not contain non-volatile components.
Wanting to test their purity, you should do a test on white paper.As long as they do not leave a permanent oily residue, then they are good.
In combinations with oily oils, they do not delay or accelerate drying, and by volatilizing without rest, they play a role in oil technique similar to water in watercolor.
A number of light oils obtained from gas tar can also be used.
These include:

• benzene,
• toluene,
• xylene,
• decalin,
• tetralin.

These substances volatilize at different rates. Those volatilizing the fastest, leave behind a white residue (toluene).
Gas tar is obtained from the dry distillation of charcoal or wood.
Charcoal, for example, is heated to a high temperature without air. First, light gas is emitted, coke is left, which finally turns into a liquid, i.e. post-gas tar. From it, many valuable products are obtained. The primary one is benzene, and from it there are derivatives.
