I've only broken a glass spoon before, and it was not replaceable. Haven't been able to find one yet.

And, oh yes, my glass/ceramic collection smashed to bits one day when a heavy shelft collapsed on them. I had a thin, clear glass steamroller, 2 glass spoons, a ceramic bong, a sherlock style glass pipe, and a mushroom glass pipe that packed hUGE hits. I almost cried that day, and all that survived was 1, small, glass spoon.

You can use the glass slider as a pipe still, like a chillium style. Just pack it and light the end.
