GOLDEN ARTIST COLORS OPEN ACRYLICS - The relaxed working characteristics and versatility allow artists to explore a wider range of techniques such as portraiture and landscape painting that rely on softening, shading, glazing and creating fine detail. OPEN Acrylics resist skinning and remain wet on the palette for extended periods while exhibiting a remarkable versatility that allows them to be used directly from the tube for plein air painting, monoprinting and screenprinting. OPEN Acrylics may be blended with GOLDEN Acrylics, Mediums and Gels, with the open time of the resulting mixtures being proportionately reduced. To maintain the maximum working time of OPEN Acrylics, use OPEN Mediums and Thinner.
