I restored this pot belly stove and sealed every possible crack. Fired it up outside and the cement harden rock hard. Very happy.

I recently cleaned out my gas fireplace and discovered that one of the logs was cracked in several places and just about to break apart. After trying to research repair or replacement online I read that this stove caulk could be used to repair bricks and ceramic fireplace logs. The logs in my fireplace are not connected to the gas line but are for decoration only, so repairing them seemed like a safe option. After I got my caulk I took the log outside and placed in on newspaper anchored with stones, then squeezed out a few inches of caulk and rubbed it into the cracks on the log with gloved hands. The caulk didn't stick well to the porous ceramic of the log, so I rubbed it on generously, trying to force it into the cracks. Then I placed the log on a foil-lined baking sheet and put it in my oven and turned the temperature up to 500°. I let it bake at 500° for about 45 minutes and then turned off the oven and let it cool down naturally. A couple of hours later I took it out and it was nice and secure and no longer in danger of splitting apart. I suppose if I wanted to be really fancy I could buy some high-heat brown spray paint and paint over the black caulk, but it's not really that noticeable in the dark interior so I don't think I'll bother.
