Catalyst Wedge W-04 Yellow

Catalyst Wedges are handy tools useful in a variety of arts and crafts: fusible paint and powder manipulation on glass, oil and acrylic painting and textured media application, ceramics, plaster, encaustics (they’re heat-resistant)—even baking and food crafting. These wedges are made of a pliable, FDA-approved silicone that’s resistant to solvents and easy to clean. They’re manufactured by the Princeton Brush Company.

The wedge W-04 (yellow) cuts a gradient of lines ranging from narrow to wider. You can get unusual effects by tilting, swerving, and curving the blade across the surface. Watch my demo video of all the wedges, or fast-forward to yellow wedge W-04 at about the 4:10 mark.
