Drawing with glass powder is a great way to explore and develop ideas. The technique frees you from the preciousness of the material, allowing you to relax and take pleasure in drawing. In this lesson, you’ll see how three people respond to a series of timed drawing exercises based on an object. To keep the focus on the process, we’ll dump each sketch before moving on to the next. These exercises make use of limited materials—just black powder, white sheet glass, and a variety of brushes and sifters.
