Will mullite break along a score?

I have a couple of the BE mullite damz that I'd like to make a bit shorter to fit into my 8" Aim kiln. Will they reliably break along a score line when hit with a hammer or pressed over a dowel? Which method recommended?

It would be best to cut it on a wet saw. If you don't have one, take the dam down to your local stone quarry or masonry center and let them cut it for you.

Your local tile store/installer would probably cut it for next to nothing. Or someone that installs stone countertops.
Wait, wouldn't one of those brown dry masonry-cutting blades work, if you went really slow? I'm talking table saw or skilsaw- those brown composite type "blades". I think that would work. They make hacksaw type blades that cut ceramic tile, that might work too.
I would saw it before I'd try to snap it on a score.
I agree with Tess that wet is best bet. Is that a Bob Dylan line?
Related question to the group: does it screw up a bandsaw/ring saw/wire saw diamond blade to cut these more clay-based, ceramic and refractory materials? I cut kiln shelves up on my MK tile saw and use the same thin lapidary blade to cut glass. How bad is that exactly? I use a thin lapidary blade.
I want a tool area here for us gearheads....

yes. you can get a masonary blade for a skilsaw for very little. wear breathing apparatus, or you'll be puking brown stuff for a while. damhikt. don't use your table saw unless you're fond of buying motors for it. damhikte.

An ordinary hack saw will work OK
Use an old one
Cut it wet
It is very soft
