This is an impasto and texturing medium for use with Artisan oil colours. Always mix thoroughly into the colour. For thick impasto, build the texture in several layers allowing each layer to dry first. This medium speeds the drying of the colours. Artisan Water Mixable Oil Colour has been specifically developed to appear and work just like conventional oil colour. The key difference between Artisan and conventional oils is its ability to thin and clean up with water. Hazardous solvents are not necessary for Artisan and artists can enjoy a safer painting environment, making it ideal for artists who share a work space, schools or painting at home. The Artisan range consists of 40 colours and has a dedicated range of 11 Artisan solvents, oils, mediums and varnishes, allowing you to achieve all oil painting techniques.
