The Third Degree Glass Factory, the largest public glass art center in the St. Louis region, is housed in what was once an abandoned 1930's service station. It offers glass blowing classes, glass education classes, a place for glass artist to practice their craft, and gallery space for display and sale of artists work. A free open house called "Third Fridays" is held, you guessed it, every third Friday of each month. Special events are held throughout the year at this unique venue, but visitors are always welcome during regular hours.
