| The
shelf here is located next to the exit flues and some of the first
layer of bricks have been removed to allow the construction of an air
intake (mousehole) under an area where side stoking could occur. We
probably will not use the grate air intake at this location, but it is
there if we feel the need. The floor of the mousehole
is just sandy dirt which should be OK because little or no ash raking
will occur there. The second layer of bricks, which form the floor of
the chamber, are high quality dense firebricks.
After a few
firings we decided that the mouseholes under the sidestoking ports were
not necessary and tended to leak air leading to patches of oxidation on
pots near them. We have sealed them off.
