    I need to replace a couple smaller firebrick in my insert. What is the best way to cut the bricks to size.

    I would think a circular saw with a diamond blade would do it.

    That's how what we use to cut clay tiles for chimneys.

    My Roto-Zip has a small circular saw attatchment with a tile blade. I used that.
    But a Regular Circular saw with the correct blade should do it.

    Tile-cutting wetsaw...You'll get straight cuts & keep the dust to a minimum

    I've even done some with hammer and chisel. You just have to be patient and do it slowly. Score a line and then keep tapping (not hitting) the chisel and moving it along the line gets the job done.

    As Backwoods suggested, hammer, chisel. I also used a hacksaw.

    Normal firebrick is easy to cut with a "masonry" blade on a skil saw. Soak it for a minute first- helps with dust.

    A wetsaw can also be used.

    A cold chisel can be used- score each corner, then each face, then a sharp strike- but ti will never be clean or accurate as a saw cut.

    Believe me- I've cut a few fire bricks :)

    Just checked out your pottery work and it is beautiful! I would like to someday purchase some for my home.. Do you sell it too or just a hobby?

    You could try a small angle grinder with a masonry wheel to score the brick then break it from there..

    I use my angle grinder with a masonry blade. I think I've used my tile saw also, but I usually grab the angle grinder.
