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 :)"

Artist in the World
ARTIST SPOTLIGHT: Nico Williams
Nico Williams, ᐅᑌᒥᐣ (b. 1989) is a member of Aamjiwnaang First Nation (Anishinaabe), currently living and working in Tiohtià:ke/Montréal. In 2021, he graduated with a Master of Fine Arts in Sculpture from Concordia University. He has a multidisciplinary and, often collaborative, practice that is centred around sculptural beadwork. Williams is active within the urban Indigenous Montréal Arts community and a member of the Contemporary Geometric Beadwork research team. He has taught workshops at The Massachusetts Institute of Technology, the McCord Stewart Museum, Crown-Indigenous Relations and Northern Affairs Canada, and the University of Toronto.
NICO WILLIAMS' ARTIST STATEMENT:
"Using the bright, tactile materiality and relational nature of beadwork, my practice looks at the ways we live through connections with objects, place, and language. Often in collaboration and community with others, I make sculptures that are sometimes highly patterned abstract geometric forms, sometimes sparkling representations of familiar objects, and always hand-woven from hundreds of glass beads. In their making, these sculptures become points of relation between the multiple hands that wove them as well as the cultural lenses through which different audiences access them.
I choose to work with forms and objects that, like beadwork, have an overt—if often overlooked—relationship to gratitude, exchange and commerce, land, and the shaping, and morphing ability of language. Sculptural geometries are a meeting point for technologies, stories, and lineages of knowledge. Translating everyday, accessible objects into beadwork re-presents regular things from our daily lives to reattune us to their attraction and code-switching, overlapping, shifting resonances across cultural contexts and modes of identity. This deep layering of held meaning about the connectivity of the past and present, cross-cultural interweaving, and both the harshness and beauty of our current reality shapes and motivates my practice."
