4900 – Glass and Woodblock Printing Fusion (Class 4900 )

Dive into the intersection of glass casting and woodblock printing in this innovative course. Participants will embark on a journey merging traditional techniques to create unique artworks.

You will learn the fundamentals of woodblock printing, and how to carve intricate designs into wood blocks to produce striking prints. Then we will explore a novel approach: using the woodcut blocks to create molds for casting glass.

By the end of the course, students will have produced 4 remarkable artworks: a traditional woodblock print, a cast glass duplicate, and a print piece of each that celebrates the harmonious marriage of these two distinct mediums.

In two sessions, you’ll create a distinctive piece using April’s unique pattern bar technique. Your choices along the way will explore the capacities of glass as a creative medium: Selecting colors—opaque, transparent, both? Cutting and layering shapes—bits and strips, irregular or not, deliberate or random? We’ll discuss the basics of firing schedules, safety procedures, and some of glass’s distinctive properties; work with glass cutting hand tools, chop saw, and belt sander; deal with serendipity; and keep your project together through multiple firings.
