peculiar feature of Gubbio majolica, unique in its kind, is
the fact that already glazed objects undergo a further baking,
so as to indelibly fix ageing coating on the enamel surface.
The coating is prepared by milling ochre powder with a spatula
on a glass plate, and by gradually adding particular volatile
liquids it is possible to obtain a very thin, liquid and ready-to-use
paste. The coating gives an antique-like appearance to white
majolica and is applied by brush with a pointing motion, so
that the colour does not excessively aggress the surface with
marks that may conceal the decoration below. Baking is carried
out in gas ovens coated with refractory material where open
fire is not present and the temperature is about 930°C.
in terms of both temperature and technique, this is very similar
to the second baking.
This assures a higher level of hygiene to the product. Once
the coating is baked, the coating is irreversibly fixed to
the enamel surface, thus guaranteeing hygiene and resistance
against collisions and abrasions.
