Manufacturing techniques

The production of ceramic objects is one of the oldest crafts of man. The molding process is divided into three main stages.

First, the preparation of ingredients.
The next stage is the molding of the part, followed in most cases the drying and firing, glazing, painting by hand and the second firing.

Like many other materials, ceramics may be formed through various methods, depending on the desired production volume.
Here are the methods used in our company.

It is used to make round and symmetrical products. The starting point is to get the proper mixture of clay, which is then extruded forming a long piece further cutted into small pieces that, once dried are fixed to a lathe and spun. Through the rotation of the lathe and the manual pressure of the artisan, the piece takes shape, which can be very large.

Except for some advanced ceramic, all ceramic products must be cooked or sintered before use.
The conditions and the temperature required depends on the material.
Some pieces need more firings: the first cooking is called firing for terracotta, the second for vitrification of the enamel or varnish, and the third for the use of metal luster, like gold, silver and platinum that need smooth surfaces for the drafting.

The glaze is applied on the piece cooked in first cooking, its vitrification happens in the second cooking. If you want to decorate with painting it must be performed on the enamel still raw and dried.

The hand painting is used for all types of ornamental and everyday objects. The colors for the decoration can be used as a color below the crystalline or above glaze and apply with a brush, sponge, swab or bloating. After painting the object is fired for the vitrification.

The technique of graffito has ancient origins and was widely used by the Greeks and the Etruscans to decorate various objects. This process consist of etching and so decorate with a sharp instrument the clay dried, glazed, or slipped making emerge the natural color.
