For centuries artists have painted oil-colour. There was nothing equivalent to this colour which resisted different temperatures, and the influence of light and age. The pictures kept their colour for years. It was only in the 1950s that the quality of acrylic colours reached such high standards that they could be used not only for painting walls but by artists as well. Still some artists prefer painting with oil-colour, because they are trained in it and don’t want to change.
The difference between acrylic colours and oil-colours are mainly two: 1. Oil-colours dry slowly, acrylics dry quickly. 2. You dilute oil-colours with a mixture of linseed oil and turpentine, you dilute acrylics with water.
As oil-colours consist mainly of pigments, linseed oil and turpentine, they dry within 2 to 6 days, depending on the thickness of the colour. Nevertheless a beautiful oil painting always has several layers of colors. So it may take some weeks or longer to finish an oil painting. That means: all the time with the smell of the smell of all the material round you.
As in younger days I worked a lot with oil-colours, I still have a lot of experience and can offer you an introductory course into “classic painting”. Within three or 4 days you will learn how to deal with the colour and how to use it “transparent” or opaque” in different layers..
