mixture of clay, 60%; sand, 15%; and graphite, 25%, kneading
thoroughly in water to a good molding consistency. Line the pail,
bottom and sides, with heavy paper and cover the core with same.
Now pack the bottom of the pail thoroughly with a 2-in. layer of
the clay mixture, and on it set the paper wrapped core, carefully
centering it. The 2 in. of space between the core and the sides of
the pail all around is to be filled with clay, C, as is shown in
the sketch, using a little at a time and packing it very tight. In
like manner make the cover of the kiln, cutting the hole a little
smaller, about 1 in. At the edge or rim of the cover encircle a
2-in. strip of sheet iron, E, Fig. 2, to hold the clay mixture, C.
Set aside for a few days until well dried.
While these are drying you may be making a muffle, if there is to
be any glazing done. This is a clay cylinder (Fig. 3) with false
top and bottom, in which the pottery to be glazed is protected
from any smoke or dust. It is placed inside the kiln, setting on
any convenient blocks which will place it midway.
