At Luke Adams Glass, artists celebrate the beauty of blown glass by teaching intimate, hands-on classes and filling a gift shop with intricate handmade objects. During three-hour introductory glass-blowing classes, students 16 and older with little to no glass-blowing experience will craft their own glass paperweight as well as one or two glass-blown vessels, such as a bowl, a vase, or a life-size replica of the Lusitania. After tinting their sculptures with the included color applications, students leave the pieces to cool overnight and may pick them up the following day. Expert instructors typically work with only three students in each class, ensuring every aspiring artist gets individual attention as he or she manipulates fire, shapes molten glass, and immobilizes migratory herds of paper with elegantly crafted desk pieces.

In the interest of safety, all students must wear cotton clothing and closed-toe shoes and bring sunglasses, a bottle of water, and a fully functional cerebrum. Groupon holders may also purchase glass-blowing equipment or gifts from the shop at a 10% discount. Enthusiasts can also bring pals to the studio’s free open house on Saturday, December 10 to check out demonstrations and craft a holiday ornament or glass-wrought Christmas list at one of the studio’s kilns.
