Well... I tried to break off the bottom of my broken crown classic and lets just say, it was ridiculously hard to do. Basically this video is just me being stupid but it can also be informative because it shows you how strong these bowls really are.
If you ever get this problem of breaking again. Look for something called a glass bottle cutter there are two kinds they run about 20 to 30$ U.S. you should be able to find them on line or at hobby stores it makes for a cleaner cut... give em a try they might save you shipping and handling cost next time. lol
Fingers crossed that never happens again...
