Catalyst Art Tools by Princeton are not quite a brush, not quite a palette knife. Flexible silicone Blades, Mini Blades, Wedges and hard nylon Contours provide maximum opportunities for creativity. Designed for use with heavy-bodied paints, Catalyst is at home with oils, acrylics, and water-miscible oils. Because they are heat-resitant to 450 F, they excel with encaustics. Try them with plaster, clay, gesso application, and printmaking, too!
Clean-up is a breeze. The silicone is easy to wipe clean, is solvent resistant, and in most cases can be thoroughly cleaned with mild soap and water. Dried paint can be peeled off the silicone surface; the Catalyst Blades can even be separated from their wood handles for cleaning and easily replaced when dry.
