Seems simple, but this operation requires great ability by the ceramist, especially in depositing the right harmonious quantity of glaze onto the entire surface.
First of all, it prepares the glazing bath, blending enamel powder with about 60% of water, then let it stend for at least 24 hours and then it pours into another container, passing the enamel through a fine sieve of brass with the help of a stiff bristled brush or a sponge common.
Before immersing the objects in the glazing bath, it's necessary to control the density, dipping a piece of biscuit and scratch it with a touch, to make sure that the thickness is approximately 1mm.

The biscuit, after being carefully dusted and sponged, is immersed in the glazing bath, with a turning moviment fast enough, leaving to drain the excess material. For this delicate process, called immersion, are adoperate the special pincers, prepared to hold the objects, clinging to the iron bits. The traces left by the pincers (the holes of the grip), are retouched later with the paintbrush. It scratches out, with a sharp blade in relief, the runs, and the retouches.
The next step is the cleaning of that part of the object that will rest upon the shelf of the kiln during firing, to prevent that the molten glaze attacks the object to the any support. Now the object is ready for decoration.
