Not quite a brush. Not quite a palette knife. Catalyst™ tools are crafted from flexible silicone to allow artists a new form of expression. Available in two unique styles: Catalyst™ Wedges are ergonomically designed to fit in your hand allowing a direct interaction with your work. 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 and Wedges. 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 be separated from their wood handles for cleaning and easily replaced when dry.
