A striking prop replica of Professor Horace Slughorn's famous hourglass. While this is a functioning replica, it is a very fragile product so we recommend that you take great care when handling it. SlughornHour Glass was a clock made of two glass vessels connected with a narrow passage through which sand and a green fluid flowed, and green serpentine features adorning the outside. The serpent imagery in its design symbolized Slyterin's house, of which Slughorn was the Head. It was kept in Slughorn's Potions Classroom on his desk, though it is presumed to also reside in his office."
