Pressed Vitrigraph Murrine Tray with Nathan Sandberg ~ December 9, 2025
Compression, pressing, and squishing are all terms used to describe the process that OnGrade Studio developed to create personalized, cuttable patterned sheet glass.
In this live interactive class, Nathan will guide you through each step as he takes a vitrigraph pot or two of sheet glass scraps and turns them into Kush style murrine. Subsequent firings will be used to transform the murrine into a very refreshing 9.25” x 9.25” x .75” kiln glass tray that is only 3 mm thick and yet not overly fragile.
Nathan will cover multiple topics including the origins of Kush style vitrigraph murrine, vitrigraph cane pulling, mounds and murrine effects, as well as pressing glass to achieve thin blanks that are appropriate for many slumping/dropout projects. Basic grinding/cold working is necessary to finish the project. The methods presented in this session are adaptable to fit many kiln sizes.
Don't miss this incredible opportunity to interact live with Nathan Sandberg and other class participants via chat! There’s nothing quite like receiving answers to your questions while enjoying the fun and synergy of learning and growing alongside a community of fellow glass art lovers.
