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 Wedges are ergonomically designed to fit in your hand allowing a direct interaction with your work. 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 Wedges are great for food crafting.Details:WedgeAvailable in multiple shapes6 wedgesHeat-resistantSolvent resistantEasy to cleanFDA-approved siliconeFor use with oil, acrylic, water-miscible oil and food crafting
