Weipa Calcined Bauxite has a particularly interesting earthy colour mix. This extremely hard mineral is mined at Weipa in Far North Queensland. Calcinated Bauxite can be used in mixed media and collage as well as for adding texture to paintings. Mix with MM2 Impasto Medium, MM4 Gel Medium or MM30 Matt Gel Medium. For the best adhesion it is important not to make the mix too dry.
