...In order to reduce the cost of oil colors, some manufacturers use gels and waxes to stiffen colors and replace traditional pigments with less expensive ones.
Our approach is different. 1980 colors are formulated with pure pigments, the finest refined linseed oil and marble dust (calcium carbonate). More affordable colors have been made with these three ingredients since oil painting began...
Emphasis mine.
I've a couple of tubes for
art class as these dry faster than my hkme studio paints. I noticed the texture was more enjoyable for the 1980 paints than winton which is kind of weird to work with as all the colours behave the same (oil paint shouldn't as each pigment is chemically different).
