3D Glass Maze We have developed the maze as one project in our course in elementary scientific glass-blowing. It satisfies a number of requirements the student appreciates. It requires some planning, some skill, can be graded by the instructor and when the project is completed i t does not have to he consigned t o the container labeled, "glass for recycling". The maze is built of 8 mm borosilicate glass and must contain a minimum of 20 hends, i joints, and i sealed tube ends. The student is not limited in design but is expected to make i t interesting. He finds himself working in restricted space and facing the problems associated with fluidity of hat glass. The finished project can be graded on the appearance of the individual joints, constriction a t bends, and the overall appearance of workmanship. We have used a 5 mm glass head to test the constriction a t bends. Insertion of metal balls and closing up the last opening completes the project and if the maker does not want to keep it an hand, there are friends willing to receive a novel gift.
