From Our Customers!

"We took the Basics from Boron class here. Malcolm was a great, easy-going instructor who adapted to each person's needs and made the experience both safe and fun. We went in having never worked with glass before but came out feeling like we had enough of the basics to come into one of their open sessions to play around and come up with some of our own glass creations. Lots of fun. Highly recommended."

— David Armstrong

"I took the Beginner’s Stained Glass. I appreciated an experienced and skilled expert teaching the class, answering questions that have come up many times before."

— Sarah Collins

I heard about Potekglass when I called another glass company to try and track down some stained glass. I would definitely recommend Potek to a friend. I think it's so valuable to have workshops and lessons like those you offer.

— Lisa Franchette

"I was really happy with the class. Malcolm is obviously used to working with beginners and non-artists."

— Emily Harper

"Malcolm was knowledgeable, laid back, and had a great sense of humor. Didn’t get impatient with my inability to light my torch! Always helpful. Great class."

— Jonathan Pierce

"So much fun (even though I wasn’t very good). Everyone I told about it was envious. I hope to come back for another class!"

— Olivia Reed

"Malcolm is an amazing instructor. Great music selection during class :)"

— Natalie Scott

"Great experience for all ages. We had an 11-year-old plus 2 adults taking the class and everyone enjoyed it."

— Michael Brooks

Artist in the World

ARTIST SPOTLIGHT: Einar and Jamex de la Torre

"Collidoscope: de la Torre Brothers Retro-Perspective", an exhibition supported by the Smithsonian's National Museum of the American Latino, features the work of Einar and Jamex de la Torre, two brothers and collaborating artists who were born in Guadalajara, Mexico in 1963 and 1960, respectively. Growing up navigating life on both sides of the U.S. Mexico Border, they share an artistic vision that represents their bi-national and bi-cultural background, as well as reflects their celebration of artistic freedom. Their artworks, spanning various mediums such as glass, resin, lenticular, and material culture, are unashamedly baroque, maximalist, vibrant, and toy with perceptions of high and low art, challenging us to re-evaluate our understandings of beauty and good taste.

Featured first: Chacamotas (2009, mixed media)

Featured second: ¡2020! (2020, mixed media)

CONTINUED: Einar and Jamex de la Torre

The brothers opened their first exhibition in the early 1990s at the Galería de la Raza in San Francisco, followed by a museum exhibition in Arizona. Since the 1990s, the brothers have continued to collaborate, creating public and site-specific artworks, participating in exhibitions in the United States and Europe, and even starring as guest judges on Netflix’s “Blown Away” glass making competition. Today, their artwork continues to utilize various glass techniques and mixed media to combine ancient iconography with symbols of our contemporary consumer culture, play with humor and irony, and mesh experiences from both sides of the U.S. Mexico Border.
