between a third and a half of the mould. A small
rim should then be made at the top, see picture
64.
10. The next stage is the making of the ash chamber
where the ash will fall down from the coal. This
requires another sausage shape length of mixture
which is then wrapped around the rim that was
formed in the previous step. Additional material
can be added at this stage to increase the length
of the chamber. It is recommended to be 10 – 20
cm, see picture 65.
11. Once the depth of the chamber has been reached
a final thin layer of mixture needs to be added;
this will secure the base. Also the surface of
the stove can be smoothed using a scraper with
water, see picture 66.
