might be added for certain considerations. The Bear Creek clay, a
red-firing clay which matures quickly at about cone 2, gives the fired
clay mixture 2 buff red colour, helps the plasticity and acts as a flux
to reduce the maturing temperature of the clay to about cone 9-10,

The ball clay, fireclay and silica sand are mixed together dry while
the Bear Creek clay is made into a slip, then sieved through a window
screen mesh and added to the dry mixture. Up to half of a small
bucket of water may be needed. I frequently add throwing slops and
reconstituted clay to the mixture also.

This is not a particularly plastic or strong throwing clay. I find I do
not like clays which are too plastic - I'm always tempted to be an
exhibitionist with them. A limited stoneware clay gives me more
scope to concentrate my efforts.

A porcelaineous body.
56 English china clay.
28 Kingman feldspar.
14 silica powder.

4 bentonite.

I obtained an English china clay after much searching in Vancouver
from MacDonald and Wilson Ltd. It is called 'Luxullian china clay".
I didn't experiment with any American china clays. The feldspar and
silica can be bought from McKenzie and Feimann Ltd., Vancouver.

I shall probably experiment to replace the feldspar with nepheline
syenite. This body throws quite well and can be used for press
mould work. It has weak dry strength and must be handled carefully
in the greenware stage. It is vitreous at cone 9-10 and will warp.

I do not think I worry about the functional qualities of clay as much as
some potters. Iam _ interested in what I want it todo for me more
than Iam in, say, its ability to hold water. I probably should hang
my head in shame for that last remark and shouldn't be called "a
potter" because of it, but that is what I feel I need in clays, at the

moment anyway.
