This
shows the Shire Horse on the purpose made prop stand. This particular
horse has been biscuit fired and so the feet are now well clear
of the table top, but when in the raw state, the feet just touch
the kiln shelf. I dust a little batt wash onto the top cradle of
the prop, but the raw clay should not stick to the prop because
the firing temperature does not go over 1140 deg. C. This is the
maturing temperature for this particular mix of semi-porcelain slip,
necessary so that all the shrinkage has taken place before colouring
and glazing. Provided no other model with glaze is fired in the
same kiln, it is still possible to spray water-based glaze and colour
onto the surface and the water will be absorbed sufficiently for
the glaze to stick. It is not easy to spray water-based colours
or glazes onto previously glaze-fired models. It can be done if
the model is heated and the spray-booth is also warmed with a hot-air
fan heater but it takes patience - otherwise runs occur.
The hole
through the mouth can be seen (also under the forelock). These holes
are for harnessing, but are also useful for placing the horse in
the kiln when coloured and when a fingermark would show.
