Modern paint technology has facilitated the production of a true Gel Medium. The purpose of the MM4 Gel Medium is to act as a clear transparent colour extender in the production of brilliant coloured glazes and as a transparent impasto for thick 3-dimensional brush and knife applications of Matisse Structure. Its prime requirement is to be thick and buttery whilst remaining fully transparent. It acts as the main intermixing medium in acrylic painting when its rich buttery consistency is required for impasto work, 3-dimensional extrapolations, multi-layer work and heavy, smooth or textural glazes. When dry, it maintains the structure, brushstrokes and textural effects of undiluted Matisse Structure colours. Its inherent firm and buttery consistency makes it ideal for application by palette knife in order to achieve heavily textured grounds.
