GAMBLIN Oil Paints 1980.
In order to keep the cost of paints down, many manufacturers add gels or waxes to make them thicker.
The approach of the American manufacturer in the line of GAMBLIN 1980 oil paints is very different, the paints are saturated with pure pigment, the best linseed oil and marble dust (calcium carbonate). Thanks to this, the consistency of any color is thick, you can work pasty, and with the addition of thinner finely.
There are no analogues on the Russian market, so I recommend to try it! It is also very advantageous, since the volume of a large tube of 150ml.
There are 48 colors in the palette
