In this two-day intensive glass class Trenton will teach many techniques for sculpting forms out of glass. Some techniques shown will be flame annealing, heat base, color work, encalmo and lip wraps. Students will be building solid glass sculptures with striking effects. At the end of the course each students will have a dynamic solid glass piece to take home. Trenton will also help each student make a piece that will then be made into a collaborative piece (by the instructor) that will be raffled of at the end of the class!


TRENTON UMEDA has been a glass blower since 2009, where he got his start in Phoenix AZ. Since then he has worked in production, scientific and pipe art studios. Trenton spent three years at a pipe production shop where he learned many solid and hollow form glass techniques. After working in the producing shop he moved to a space where he worked on platinum electrode conduction cell glass. Since Phoenix, Trenton has worked in glass shops in Grants Pass, OR; Portland, OR; and Eugene OR. He currently holds a studio practice in Salem, OR.

“My glass practice is fueled by a passion for making unique patterns with lip wraps and encalmo. I enjoy building sculptures and hollow forms and challenging my self in the studio by trying new ways of combining these techniques.”
