Tired of throwing the same old boring forms? Let’s test the limits to see what clay can do. This higher level (intermediate to advanced), 1-day class will explore bottles, closed forms, double-walled pieces and more.

The best part? There’s absolutely no pressure to get any of this right - we’ll be focusing on technique only and not actually making any pieces to keep. So get bold and take those advanced forms all the way to the limit!

This class takes place at Groundworks HILL, 1010 Aurora Avenue, Boulder, CO. 

PLEASE NOTE: This one-time class runs for 2.5 hours. You will not have access to the studio outside of the scheduled class time and all work will be completed during class time. You will also not have access to our other locations.

Ages: 16+

Hate glazing? You’re not alone. Join us for this special one-time, higher level (intermediate to advanced) class exploring an alternate surface treatment called Terra Sigillata (Sig - pronounced ‘sij’ - for short). Terra Sigillata means “sealed earth” due to it being a super refined slip that leaves your pieces with a silky, smooth finish.

Terra Sig goes on best with bone-dry pieces, so Groundworks will provide flat tiles or cylinders to practice on. We’ll fire them after the class and let you know when they’re ready for pick-up. Come get a crash course in this ancient decoration technique.

This class takes place at Groundworks MAIN, 3750 Canfield Street, Boulder, CO. 

PLEASE NOTE: This one-time class runs for 2 hours. You will not have access to the studio outside of the scheduled class time and all work will be completed during class time. You will also not have access to our other locations.

Summers are always muggy, so why not come learn how to make a beautiful hand-built mug? This adult camp will spend the first part of the week focusing on what it takes to construct a functional hand-built mug. The ins and outs of weight, drinking lips, handle placement and more and how that can affect your finished pieces. The second half of the camp will turn to surface decoration and ways to decorate beyond just glazing. Students will have the opportunity to make 2 or 3 mugs a piece to explore their different ideas and try out the different techniques. Pieces will be fired by the studio and ready for pick up a few weeks after the camp ends. 

This class will take place in the hand-building classroom upstairs at Groundworks Hill, 1010 Aurora Ave. Boulder, CO

Are you lazing in your glazing? Sleeping on slip? Craving more carving? Let’s dig into it! In this one-time 2.5 hour class, we’ll do a deeper dive into surface decoration techniques such as sgraffito, mishima, carving through wax, and using slip as texture. 

Groundworks will provide flat tiles in a variety of different clay bodies for students to practice surface decoration on.
