Golden Rules
Never play the bowl with excessive force
Do not hit the bowl with the stick. Tap lightly if you need to.
Carry it with your arms around it to protect it from walls and furniture.
Keep your bowls a foot apart from each other when playing.
Do not play a very large bowl in a very tiny room.
Play on the outside of the rim and not on the inside. Playing on the inside appears to increase the stress placed on the bowl.
Because shattering is a possibility never place your head in the bowl when it is resonating or place the bowl on top of someone when playing.
