Clay • Adult • Clay Tablets for Wall Hangings 5B • WED (Sept 27 - Oct 18) • $140 • HILL
with Anne Marie Boardman
Clay tablets have served as some of humanity’s earliest tools for storytelling, documentation and communication. They are an effective way to explore the rich history of clay as a surface for creating a sort of visual language. Through mark-making, symbols and layering, participants would be able to develop a personal visual vocabulary that communicates ideas, narratives, and feelings without relying solely on written words. The class will cover making ceramic slabs and tiles that can hang on a wall and focus on creating a intuitive visual language through surface design and material exploration.
This class takes place at Groundworks HILL at 1010 Aurora Ave, Boulder, CO
This class meets weekly for 4 weeks on SUNDAYS.
Class does NOT include additional open lab time or clay. All work must be completed during class time.
