I've looked at storage bricks but eBay is a bit dry down here in Surrey, I either have to travel 100mi for cheap bricks or take 3 pack heater bricks for £25 so proper clay fire bricks @ £2.10 is still the best option.
Dave, you've made several ovens and looking at your website had commercial success. How should I build my oven with the materials at my disposal listed?
- hardcore
- ceramic fibre board
- fire bricks
- dense castable over sand dome former
- 25mm ceramic blanket (as you recommended vermiculite layer figured can reduce the thickness as easier to apply layers on thinner blanket and vermiculite will provide lost insulation)
- vermiculite/cement mix
- render
