Thanks, everyone for all the help. I ended up using some refractory cement, pottery type clay, and perlite for my heat riser. Seemed to work Ok. Called around to quite a few places an no luck yet. I will keep trying and keep my eyes and ears open. Thanks again for all the help. I have learned a lot here.

Hi, I am newbie. I am currently constructing a rocket stove mass heater. I have made the burn chamber and am ready to make the riser. I was using clay that I found in a creek bed with perlite and some refractory furnace cement (Menards). The clay is a blue grey and is pretty sticky. After a lot of reading I am now doubting the clay I am using. So I am wanting to use Lincoln 60 fire clay. I haven't had much luck finding any in the Des Moines (Central Iowa area). I am wondering if anyone knows where I can purchase some or a good alternative in the Iowa area.

Any help would be much appreciated.
Thanks!
