Clay • Adult • Level II THROW DOWN • Wed (Aug 26 - Oct 14) • $300 • HILL

$300

with Colleen Grande

Calendar Aug 26, 2026 at 7 pm, runs for 8 weeks

Inspired by the show The Great Pottery Throw Down, this class is designed for intermediate students who want to break out of their comfort zones, be challenged, and have a ton of fun doing it.

Each week will bring 2 prompts:

  • The Technical Challenge: A fast-paced surprise designed to test your skills. Think speed-throwing a teapot, throwing blindfolded, or racing to create five identical bowls.
  • The Main Make: A focused project where you can let your creativity shine. You’ll tackle complex, multi-piece creations like nesting bowl sets, thematic tile collections, full dinnerware sets, or tea sets.

Is this class for you? If you have the basics down and are looking for a unique, high-energy challenge, absolutely. This class thrives on community and shared experience - it's at its best when everyone jumps into the challenges together.

(Please check the class prerequisites before enrolling)

Clay • Adult • Clay Tablets for Wall Hangings 5B • SUN (Sept 27 - Oct 18) • $140 • HILL

$140

with Anne Marie Boardman

Calendar Sep 27, 2026 at 9:30 am, runs for 4 weeks

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+

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