Catalyst is an innovative new line of creative tools for artists. Catalyst Blades are a new kind of tool made of engineered silicone. Not quite a brush. Not quite a palette knife. Catalyst tools are crafted from flexible silicone to allow artists a new form of expression. Catalyst Blades are mounted on artist brush handles offering a blend of tradition and innovation.Designed for use with heavy-bodied paints, Catalyst is at home with oils, acrylics, and water-miscible oils. Because they are heat-resistant, they excel with encaustics. Artists are using them with plaster, clay, and even frosting. Made of FDA-approved silicone, Catalyst Blades and Wedges are great for food crafting.Clean-up is a breeze with Catalyst Blades. The silicone is easy to wipe clean and is solvent resistant. Clean up in most cases can be done with mild soap and water. Dried paint can be peeled off the silicone surface. Catalyst blades can even be separated from their wood handles for cleaning and easily replaced when dry.
