Pittsburgh Glass Center offers multi-week glass classes for all experience levels, from beginners through advanced students. Classes meet in 3-hour sessions dedicated to covering a variety of material. In each session, students will see a demonstration of the skills they will be learning and practicing that session, followed by hands-on application for the remainder of the class.   Attendance Classes are structured in a way that students build upon their glassmaking skills each week. Students are strongly encouraged to attend every class, so as not to fall behind. In cases of an emergency and with advanced notice to the instructor PGC can sometimes try to accommodate a makeup session. Due to studio availability, makeup sessions are not guaranteed. If you need to be absent, you must email, call, or text your instructor in advance. Contact information is provided on the first day of class along with your course syllabus.   CMU and Scheduled Semester Breaks Some 8-week classes are available for students at Carnegie Mellon University to enroll for college credit. As such, 8-week classes usually accommodate a one-week university-scheduled semester break (spring and fall). Breaks are limited to one Saturday and one Sunday to try and keep all of our classes on the same schedule. Dates of classes and breaks are online when registering and outlined in the class syllabus received on the first day of class.
