New, unused item. Catalyst Silicone Wedge W-05 If you purchase this item with other items, we will offer a further discount. The following is an excerpt from the Holbein HP: A new tool, neither a brush nor a painting knife "Catalyst Wedge & Blade," a silicone tool that creates free expression without being bound by convention. Developed for use with viscous paints, Catalyst allows you to manipulate oil paints, acrylic paints, and water-soluble oil paints as you wish. With a heat resistance of approximately 230 degrees Celsius, it also expands the possibilities for encaustic painting. From plaster to clay, the usage is up to the artist. It can also be used with general painting mediums. Cleaning is also very easy. Most dirt can be washed away with mild detergent and water, and dried paint can be easily peeled off the silicone surface. In addition, the silicone blade can be removed when washing and put back on after drying, allowing it to be detached from the wooden handle. Type: Art Supplies Manufacturer: Holbein
