SPECIES
past painters spoke "oil essential "because they came from the distillation.
Essences have the function of extending the oil color and allow to obtain the desired fluidity. The use of gasoline as paint thinner was in Van Eyck. These extenders that make thin dull color. (Some artists prefer this aspect of the painting are employed only). PLANT SPECIES
:
-L turpentine (Contains terpenes), volatile, it is most used, and is the type of paint thinner oil. To be of good quality, turpentine must be clear, or colorless like water. It comes from plant resins is an extract from the resin of the maritime pine, fir or other conifers, Rosin is the residue of its manufacture. It impoverishes relatively little dough for this reason, the apparent slight to medium. Dries quickly by evaporation, it is used sparingly, is a good bulking agent that increases siccativity of oil colors. It facilitates the layering of colors and gives the finesse required to bring the binder to adhere to the support colors. There are
:
Turpentine CORRECTED-CORRECTED OR BI having undergone one or more distillation to extract all the impurities and to increase its fluidity, is that it is used the most in oil painting, rather, in the first layers, only thinner, it gives a matt and dull paint.
-Venice turpentine (balsam of Venice):
one color slightly amber, it is extracted from the working mélèze.Elle supplemented with turpentine and gives the colors very vivid. It eliminates the "fullness" when nl'emploie as nail painting. But its drying power is low it must add a drier in the use of certain colors.
-THE ESSENCE OF NEWT:
is a natural essence extracted from the lavender, it contains camphor, and ether resin which gives it a distinctive odor. It is used rather mixed with turpentine. His slow volatility gives a very smooth paste. The painter Rubens employed a mixture of turpentine Ave Venice, it still used today by museum conservators to the works of Flemish.
MINERAL SPECIES:
They are derived from petroleum, they have almost the same properties that turpentine.
-The White spirit is a good solvent for oils. It evaporates faster than turpentine, without grease. It controls shine some paints, and tends to impoverish the dough. I prefer to keep it as cleaning brushes and brushes. There are essences of oil paint ground, which has no residue and remains clear as possible without yellowing. (Essential oil in Vibert example).
