with John Minkler

This class goes beyond the basics and explores more complex wheel-thrown forms and surface decorations that emphasize the unique qualities of a Bourry Box wood-firing. As the wood burns, the ash travels throughout the kiln leaving a subtle yet distinctive trace on the pots therein.
The Bourry Box kiln is at an off site location in Longmont. Participation in the loading and firing of the Bourry Box wood fire kiln is a required component of the class. If you don't participate in the loading process, we can't guarentee your pieces will make it into the kiln. Kiln loading will be Oct. 16th. Kiln firing willl be Oct. 18th.
Ages: 16+

Wood • Adult • Level I: Introduction to Wood Turning • Tue (Sept 23 - Oct 14) • $275• MAIN
with Dennis Mulherin

Learn to turn! This class will be an introduction to using the lathe - a machine used for shaping all manner of cylindrical forms (think bowls, vases, furniture legs, even pens!).
Over the course of four weeks, you will learn about the tools directly associated with the lathe and their primary uses. From practicing spindle turning to learning how to make bowls, we will learn the two major turning techniques that can be explored to no end with further practice. This class will be as hands on as any class can, wasting no time before getting students turning with tool in hand (don’t worry, we’ll go over safety basics too). Beyond the basics we will practice, practice, practice. You will not want to turn your machines off!
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!
