color:#1F497D'>I then formed the final mix into triangular shaped bricks, dried
them and fitted them into the frustum (chopped off cone) section of a furnace made
from steel. I used straight clay as filler between the joints. I also made a 1”
thick wall pipe using a cut off tin for the outside and a piece of PVC pipe for
the inside. The mortar pipe fitted into the furnace outlet pipe fitted to
the bottom of the cone. Mounting the furnace on bricks (to let air in from the
bottom), we made a serious covered fire inside the refractory to cure the lot. It
has come out very well. Anyone looking for photos, send me a mail and I will
email them to you direct.<o:p></o:p></span></p>

Subject: [Stoves] Mortar Mix Recipe?<br>
<br>
<br>
Greetings!<br>
<br>
I plan on building a rocket stove/masonry heater. Can someone<br>
recommend a mortar mix recipe for the firebrick, limestone and blue<br>
slate?<br>
<br>
Thanks,<br>
<br>
Jay Scott.<br>
