Sunny South Africa Holiday Build
I am planning to do my first build during my 1 month break from work.
I have recently purchased a new house and there is half a constructed base in the graden that I plan to bring to the correct level and then build a 900mm refactory cast dome on it.
I have sourced a suppllier for a refactory cast material for the inner layer and oven base and the one they recomend has the following composition:
So it is essentially:
1-5% Aluminium Oxide
10-20% Calcium Alluminate
80-90% Calcined Clay
Max Service Temp: 1550 deg Celcius
What are your thoughts on this material? And what thickness do you recomend?
I have a local modified Perlite mix that has great insulating properties that I plan to use as insulation both under and around the dome .
I look forward in sharing my build with you!
