Once the desired shape the object is made to stand about a day and when the hardness reaches "leather", always using the lathe, is lightened, smoothed, turned with the appropriate tools to enhance the forms.
With this type of modeling are created exclusively sacred images, statues and tiles requires the aid of a plaster mold. So there they lie in strips of clay previously prepared with care to make them adhere perfectly to the walls of the mold and at the same time being careful not to leave air bubbles between the strip and the other as the cause of the rupture. After a few hours the clay becomes detached from the mold, is then extracted and finished by hand. You dig around the high to remove the undercut and then bring out the subject imprinted in the tile.
The first cooking
Past few weeks we shall the first cooking of pieces completely dry and free of moisture, are then placed in the furnace, creating a sort of castle with specific plans in refractory material. The cooking, which always begins in the morning, reaches 980 ° C very slowly and very slowly we have to lower it to open the oven. In fact, it takes about 36 hours to see the final outcome.
The red object, instead, to be painted, it must first be glazed, ie coated with a layer of enamel - always kind of glass, unlike the crystalline is not transparent -. The enamel, which can be done by immersion - usually when the object is small - or spray, as well as to protect the piece from wear, is designed to facilitate painting.

Are then recreated the typical decor of the shop that over the years have changed and have been integrated with modern styles and easy to place in less traditional settings.
