Pizza oven #8

Some progress to report. While waiting for the fire bricks I did do some work on the BBQ side as you can see, I am going to make a back wall for the BBQ but that will happen when the oven is complete.

I picked up the fire bricks and pizza hearth tiles on the weekend. Took a while to cut the pizza tiles (a thin fire brick) to size but got it done, then a thin layer of sand & cement on the base bricks so they lie flat and then the tiles go down. Once that was done I started on the oven dome which means that all my firebricks need to be cut in half, not too difficult though.

My main conumdrum was what to use for the mortar. Andrew next door use refractory concrete/mortar, but that costs $100 for a small bucket and he went through 2.5 of these and I didn't want to spend that sort of money. Robin in his article uses clay from the garden mixed with sand and cement, but the guy from the place I bought the fire bricks recommended using Lawsons Super, a cement admixture. These guys all know more than me!

So while Andrews option was obviously good, it was expensive, and Robin has done heaps of ovens so there is no reason to believe that the clay/cement mixture won't work. So I've gone with Robin's mixture, but added the Lawson Super to make the mixture more workable and for insurance. But I won't know if I've done it wrong until it's too late, bugger.

But at least it's starting to look like an oven.
