Using a total of 10 grams of colour, well mixed in a
dry state (through a tea strainer) and doing the mixing
as above, a wide range of subtle colour variations can
be achieved.

Colourants which have been tested with this basic
concept are: iron - copper - cobalt - nickel -
manganese - rutile.

Many other oxides could also be used as well as under-
glaze colours, body stains, etc.

RESULTS

By now, a great deal of information had been gathered
by testing ome basic glaze and this showed the students
how to shift a glaze from a clear range to a matt range,
and back. Different balances of materials had produced
interesting variations.

Additions of materials had altered the kind and quality
of the fired glaze surface. Colour tests had indicated
a range of intensity and surface quality. Variations in
colour response to different fluxing materials had been
demonstrated.

From this investigation, each student selected several
results of interest and then proceeded to investigate
the range of uae (cones 6 - 9) and the versatility
(oxidation, reduction, salt) of the glaze. It was then
used on different clay bodies (light, medium dark) in
varying thicknesses of application. Its use over slips,
underglaze colours, stains,pencils and colouring oxides
was tested. Methods of application were also explored
(pouring, dipping, spraying, brushing and sponging).

some glazes worked well when applied by several of the
methods of application, again giving a variety of surface
