I've just completed my pizza oven and have fired it a few times now. This weekend we had a few friends round for beer and pizza while watching England win the Grand Slam. Got the oven very hot and I was really pleased with the way it cooked and the heat retention. Oven was still 100 degrees C next morning - after having slow cooked a leg of lamb over night. What I was not too happy about was the crack that appeared all the way down my chimney. I used a normal chimney from Jewsons - I assumed they were designed for high temps - apparently not! Anyone have any advice or comments on this? Will I need to change the chimney?

Anyone have any advice or comments on this? Will I need to change the chimney? Your chimney's way closer the fire than a normal household one, and so that's probably why it cracked. Mine did too (used old clay drainpipe) and haven't bothered to replace it yet as it's still functional - so the answer's probably no, you don't need to, but if you do, maybe consider a steel flue.

I bought my clay chimney pipe from Kiln Linings, and after several hot firings found I had a fine vertical crack line down both lengths from top to bottom. As it was going to be enclosed by a brick chimney, I didn't worry.
