The following phase is enamelling, i.e. the application of glazing material.
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.
