SLIPS AND ENGOBES
Continued from Page I

Combinations of china clay (for white:
ness) and ball clay (for shrinkage] form
the basis of engobes which may be for-
mulated for application at the damp, dry
or biscuit stage. Shrinkage control ia
obtained by adjusting the rate of china
clay (low shrinkage} to ball clay (high
shrinkage). The addition of a flux may be
necessary in order to develop some vil-
ification, otherwise the engobe simply
brushes off after firing. Felspars are
used for the high temperature range.
Other additions may include fillers (Mint),
hardness (borax), binders or gums (CMC}
and opacifiers [tin or zircopax].

Less complex engobes can be made us-
ing combinations of P-V. clay and OM-4
ball clay. The folowing starting points
are suggested for working out your own
formulations;

Additional fluxes will be required in the
low temperature firing range (below
Cone 6).

Application

Sips and engobes may be brushed,
poured, trailed, sprayed or dipped. Each
technique has tts own special quality.
Bear in mind that if the application is on
greenware, timing 15 important.
