[Stoves] Unity Stove Reply to Richard Stanley

[T Hastings]

I can't say I am 100% sure on how to reply to comments on the list but
anyway....

Richard, for the Unity Rocket Stove the inner core and pot support are
cast together with the insulating surround. The outer finish surface
is then put on afterwards like cement render. In the video
https://www.youtube.com/watch?v=PgxTzNGml6w at about 30 sec in you can
see one side before the render is applied.

And yes, Kaolin clay is one of the ingredients.

Kobus Venter and Rok Oblak and probably a hundred others have experimented with the same thing in years past but you have managed to nail it down:   Clever stuff and all the best to you...
