Hi I'm embarking on my very first pizza oven build and I'm thinking of going down the gym ball casting method. I work for a very large company that uses fire test furnaces and we have just had a re-line. The company that done the work gave me some fire bricks for the floor and some bags of a product call Furncast which I cannot find any information about at all. Our furnaces run at over 1200°c so this casting concrete can manage heat. My question is has anyone heard of this product as googling doesn't help and will this be a good product to cast a dome pizza oven?
Many thanks
