Building a cast oven

[tim1989]

So after a year of building my brick oven I moved just after finishing it now it's time for a new one iv planed a 700mm internal oven which I will sit on a metal frame. Only thing I can't work out is where best to buy castable refractory concret? Iv found this does anyone know if its up to the job? Or if i can get it cheaper else's where http://www.kilnlinings.co.uk/categor...tory/castable-
