Catalyst Blades are an innovative new product; not quite a brush and not quite a palette knife. This versatile tool works great with heavy-bodied paints and can be used with oils, acrylics, water-miscible oils, and even plaster and clay. Catalyst blades feature flexible silicone heads secured atop beautifully crafted artist brush handles. The unique characteristics of silicone offer versatility in an amazing variety of applications. Heat-resistant and FDA-approved, the silicone heads allow Catalyst Blades to be used safely in many mediums, from encaustics to food crafting. The silicone is solvent-resistant and easy to wipe clean with mild soap and water. Blades can even be separated from handles while cleaning and replaced when dry.
