While it's true that w anything glass or ceramic, there are no absolutes, I have had a couple of shows where we had to break plates, glasses and other stuff on stage every nite, including a bottle that had to shatter from a gunshot and all within 10 feet of the front row of house. As these were mostly in small-ish houses, we were concerned as much about the audience's safety as the actors'. Our best solution was pre-breaking and gluing back together all the pieces we needed - and we would prep a week's worth at a time. Amusingly, there were a couple of nites when a plate didn't break at all, and a couple when they broke NOT along the pre-scored lines, but most of the time it worked beautifully, and best of all, minimal shatter and almost never did anything leap out into the house.
Glass items had to be thick enough, and ceramic cheap/thin enough to work, and we had to plan on losing a little over 1 each nite (since the pre-scoring sometimes broke a piece beyong repair) , but generally speaking, it was a great solution.
Good luck, and do your geometry to make sure the angle it's being broken from doesn't send flying pieces into the house, nor in the direction of the actors. (Wow, math in daily life...!)
