Gamblin 1980 Oil Colors are made with the same dedication and pure pigments that go into their Artist Oils'. In addition, they use the same process of mixing, milling, filling, and hand labelling. To ensure the 1980 colours are affordable, Gamblin formulates them with pure pigments, refined linseed oil and marble dust (calcium carbonate). This is different to many other paint manufacturers who use gels and waxes to stiffen colours, or even replace traditional pigments with less expensive ones. With 1980 colours, artists can pay less and experience colours that are great quality, without homogenized texture or muddy colour mixtures. Pdf CC_Gamblin_1980 Gamblin 1980 - Colour Chart.
