New to glasswork and don’t know where to start? You’re in the right place! Our Glass Studio Sampler class is the perfect place to begin your journey of learning and understanding the material and techniques of making beautiful art with glass.

This class will spend four weeks going over low-fire glassworking techniques like kiln fusing, sheet glass cutting and coldwork (working with unheated glass), and hot glass / hot sculpting (reshaping heated glass with either torches or kilns). The projects will be simple and may vary depending on the material and technique being covered that week.

This class has no prerequisites and is specifically set up for absolute beginners to this art form. Our Glass Studio does have 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-toe and heel shoes, and natural material clothing, i.e. cotton or linen, long pants are recommended. 
  • No loose or dangling jewelry, long earrings or scarves.
  • If you have long hair, please have it securely tied back from your face.
  • We will provide safety goggles, but if you have your own and would like to bring them, please do!

Ages: 16+ 

All supplies and materials will be provided.

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.
