following phase is enamelling, i.e. the application of glazing
The enamelling bath is prepared by mixing powder enamel with
about 60% water, it is left standing for at least 24 hours
and is then poured into another container, by filtering the
enamel through a thin brass sieve with the help of a hard
bristle brush or a common sponge. Before immerging the objects
into the enamelling bath, it is necessary to check the density
by immerging a piece of biscuit scratching it with a point
so as to ascertain that the thickness is about 1mm.
After the biscuit has been accurately dusted and sponged,
it is immerged into the enamelling bath with a fairly quick
rotary motion and the exceeding material left to drip off.
This rather delicate procedure is called immersion process
and it implies the use of special pincers, which are designed
to hold the objects held by iron points. The traces left by
the pincers (the holes due to the hold) are later refined
with a brush. Drippings and touch-ups are scraped away with
a sharp blade. The following phase is the cleaning of the
part of the object that will be lying on the oven during baking,
so as to avoid melted enamel sticking to the object on the
supporting shelf. The object is now ready for decoration.
