People who live in glass houses shouldn't throw stones, unless they're glass blowers, who often destroy their homes just so they can re-inflate them. Add a touch of glass with today's Groupon: for $99, you get a four-hour glass-blowing class at Glasscraft in Golden (a $199 value). This deal is valid for any Boro 101 or Beginning Beadmaking class on Glasscraft’s schedule.

The skilled craftspeople at Glasscraft educate aspiring artists in the intricate art of molding glass in the tradition of founder Homer Hoyt, who wrote the book on glass blowing. After selecting either a bead- or sculpture-focused lampworking course, apprentices of all skill levels spend four hours creating take-home masterpieces under the tutelage of Glasscraft’s seasoned glass blowers. Students can manipulate glass into an assortment of colorful jewelry beads during the bead workshop, allowing them to cool slowly overnight before collecting them to display around necks or debutante sausage links. The sculpture workshop pairs glass grapplers with hard glass, with which students create sturdy sculptural flowers. An average of six students makes up each class, allowing each crafter to receive any necessary one-on-one attention from Glasscraft’s staffers, who pride themselves on catering to their pupils' needs and keeping their studio safe, clean, and as well alphabetized as Mr. T's vitamin cabinet. Groupon customers also receive discounts on future glass-working classes.
