Building Your Tool Box

with Nate Cotterman & Adam Holtzinger

$950 MEMBER PRICE: $950

This five-day class will focus on skill building through repetition of technique. We will work through simple forms that can be used as building blocks for many complex ideas and designs. We will address everything from the arrangement of your bench and how you move through the shop, to starting and finishing your piece with accuracy and intention. We will use drawing and calipers to pre-visualize our ideas prior to going into the shop. Color techniques will be covered as skills develop, but this course will mainly focus on blowing glass accurately and efficiently and being able to repeat the process to get desired results.

This class welcomes those with some glass experience and the desire to enhance their skillset. Those interested should know how to gather and the basics of blowing glass.

Evening Open Studio

Studios are open until 9:30PM for students to practice. Depending on the class, process, and techniques, this time might be highly suggested by instructors for students to use. In other classes, this time might be considered optional.

For more information, please review Summer Intensives.
