Reviews

"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."

"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."

"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. Malcom is obviously used to working with beginners and non-artists."

"Malcom 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."

"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!"

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

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