I have been reading and tinkering with rocket and tlud stoves and I am interested in doing some experiments with raku clay and raku clay with ground soft fire brick mixed in.. as material for the fire box and riser.. possibly the bell as well.. in the spirit of so much I have read.. it is what I have... I am intrigued by the vortex cook stove design and the simplicity of the batch box mass heater.. I think that by using inclusions for insulating the riser and by bisque firing the components it will hold up to the temperatures well.. I am a pretty crafty monkey but I would love input from you experts so I don't have to reinvent every little bit.. I am going to start with a small pellet feed heater with two goals 1: portable (in a bucket) 2: platform for testing clay blends.. P.S. I have long term eyes on johndepew''s coffee roaster idea

Welcome to the forum, billlamm.
Fireclays are mostly Alumina and Silica. My local clay is like that, so I cast a piece out of it to see how well it would work and it's been perfect.
Look forward to seeing what you come up with.

I see some references to ceramic fiber blanket being used, and possibly stiffened with? Kiln wash or thinned out refractory cement? If I were to make a ceramic tube and line it with ceramic blanket (Un treated) would it be to porous or soft? Get blasted apart by the fire?
