Then added to the solution of high-purity linseed oil or linseed oil and a few drops of an antiseptic (phenol). You need to pour the oil in small portions and intensively stirring the solution. A sign of the quality of the emulsion is the uniformity of the whole: should not be separated and float in the oil.
Oily soil are obtained by using special oil white. After applying several layers of white canvas is aged for a year and a half to consolidate the layer.
