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. 

Ages: 16+

Curious how to use milling machinery– table saw, chop saw, jointer, and plainer? This beginner-level class will focus primarily on milling: the fundamental process of measuring, cutting, and preparing wood for a project. Over the course of 4 weeks, you'll learn how to safely use several of our milling machines to cut and shape wood, as well as some of the basics of joinery (joining pieces of wood together), and shaping and finishing with hand tools. We'll walk you through the whole process of creating a simple but beautiful functional piece that you'll want to brag to all your friends about.

This class has no prerequisites and is open to beginners and seasoned woodworkers alike, but our Wood Studio has some safety basics before anyone is allowed to join in the fun (failure to meet these requirements will result in not being granted access to the equipment): 

  •  Please come dressed in close-toed shoes, a shirt that can be tucked in and either short sleeves, or sleeves that can be rolled up past your elbows. 
  • No loose or dangling jewelry.
  • If you have long hair, please have it securely tied back from your face.
  • We will provide safety goggles and/or full face shields, ear protection, and face masks to cover nose and mouth, but if you have your own PPE you would prefer to use, please do!

Please note that students only have open lab access corresponding to their specific class area (e.g., milling open lab is separate from turning open lab).

Ages: 16+ 

All supplies and materials will be provided. 

These classes include open studio time.

Will be available to register on Monday, July 27 at 8:00am at 8:00am.
