Manufacturing techniques

Before ceramics, land: preparation
Salerno, the extraction of clay has always been very easy, because the ore, of exceptional quality, are located in very large quantities, almost on the surface. Salerno, the extraction of clay has always been very easy, because the ore, of exceptional quality, are located in very large quantities, almost on the surface. Today, four quarries are in operation, the reserves of clay are such that there are still several centuries!

The technical preparation of rolls of clay has not changed. The technical preparation of rolls of clay has not changed. While  evaporation ponds of yesteryear have given way  filter press.

But whether in the factory specialized in EIG workshops or autonomous smaller, modern extruders produce in quantity degassed material of great finesse.

Form: Form shaping: shaping
The “bread” of clay are delivered and / or produced each day depending on demand. The “bread” of clay are delivered and / or produced each day depending on demand. The work can begin. The work can begin. In the workshops magic will happen . In the workshops magic will happen .

Each craftsman puts his knowledge, his passion, his tenacity, his personal research in the service of this land for a different product. Each craftsman puts his knowledge, his passion, his tenacity, his personal research in the service of this land for a different product.
Whether it be stamped, molded plaster or in part, whether cut or gauge cookie cutter, mechanized or not is the main shapers of the skill of the operator who determines the final result.

Often refined finger, and flattened by pressing on a marble tiles are then arranged in stacks or on racks for drying. Often refined finger, and flattened by pressing on a marble tiles are then arranged in stacks or on racks for drying.

The material: The drying and cooking material drying and cooking
Drying, or accelerated by natural ventilation and / or heating, allowing the evacuation of almost all the water shaping.

It is all the more difficult and long as the dimensions are important and complex shapes. It is all the more difficult and long as the dimensions are important and complex shapes.

The cooking is a step in the manufacturing process. The cooking is a step in the manufacturing process. Of course it determines the mechanical properties of the product, but also to terracottas not enameled, its aesthetic qualities. Of course it determines the mechanical properties of the product, but also to terracottas not enameled, its aesthetic qualities. Depending on the temperature and atmosphere of cooking, color varies from red brick with intense red or yellow ocher, or more shades of pink or cream.

For cooking with reduction (with lack of combustion air, change color of the earth), the provision of tiles in the oven determines the color variations: flambé when cooking is done singing, bordered for a cooking batteries.

For two companies that still cook with wood, the burning of long larch giving the flammage “random mix of these shades of color. For two companies that still cook with wood, the burning of long larch giving the flammage random mix of these shades of color.

The color glazing and decoration The color glazing and decoration
The enameling is deposited on the ceramic tiles, called “biscuit”, one or more layers of finely ground colored glasses. The enameling is deposited on the ceramic tiles, called “biscuit”, one or more layers of finely ground colored glasses. Cooking transforms this glass enamel by the magic of the merger. Cooking transforms this glass enamel by the magic of the merger. The enamel is first put in aqueous suspension, and then deposited on the tiles. The enamel is first put in aqueous suspension, and then deposited on the tiles. The biscuit absorbs water, and the enamel is deposited on the surface of the tile, according rendering sought enamelling is done by spraying, manual (with a pistol) or partially mechanized, the bell, to the ladle or by dipping. The biscuit absorbs water, and the enamel is deposited on the surface of the tile, according rendering sought enamelling is done by spraying, manual (with a pistol) or partially mechanized, the bell, to the ladle or by dipping. The cooking temperature between 950 and 1000 °, allows an infinite number of colors and aspects. The cooking temperature between 950 and 1000 °, allows an infinite number of colors and aspects.

The decoration is done mostly by brush on glaze raw (bonfire), using metal oxides pure or mixed with a drink, the “color painting.” The decoration is done mostly by brush on glaze raw (bonfire), using metal oxides pure or mixed with a drink, the “color painting.” The decor and enamel are then cooked in one cooking.

But according to achieve the sets, techniques can be used stencil decoration, screen manual, inserts, print raw, and so on. But according to achieve the sets, techniques can be used stencil decoration, screen manual, inserts, print raw, and so on.

It is sometimes necessary to carry out several successive firings at different temperatures, to get the desired result. It is sometimes necessary to carry out several successive firings at different temperatures, to get the desired result.

The lava, diversity of forms and appearance The lava, diversity of forms and appearance
Proceeds from volcanic magma, lava is the state of natural rock. Proceeds from volcanic magma, lava is the state of natural rock. Extracted and charged in installment in the quarries, it will then be cut, shaped and glazed according to the wishes of the client. Extracted and charged in installment in the quarries, it will then be cut, shaped and glazed according to the wishes of the client. The lava has the peculiarity to be cooked without losing its mechanical properties, all offering opportunities for training and technical or artistic cuts that normally found in marble, granite or basalt.

The lava is also an material that does not freeze, allowing the realization of surface for elements outside, subject to climatic extremes. The lava is also an material that does not freeze, allowing the realization of surface for elements outside, subject to climatic extremes.
No joint, the glazed lava is ideal near water points or cooking. No joint, the glazed lava is ideal near water points or cooking. The different holes, machining edges, disbursed and grooving, or any other processing are made for finishing.

According to the desired final appearance, the ceramist on each plate washing all or part of the following: sanding, backfilling of the porous nature of lava through plaster, sanding flat or hollow.

The dish is usually cooked first to stabilize the plaster. The dish is usually cooked first to stabilize the plaster.

Then comes the enameller. Then comes the enamel. The different glazes are deposited in layers. The different glazes are deposited in layers. Again, depending on the color and effect, there will be a single enamel is a layer of sub enamel, white enamel and a color transparency. Again, depending on the color and effect, there will be a single enamel is a layer of sub enamel, white enamel and a color transparency.

The volume: pottery and accessories The volume: pottery and accessories
In addition to the production of flat products described above, the potters produce parts by volume: dishes, bowls, Tian, know-door, balusters, furniture, etc.. In addition to the production of flat products described above, the potters produce parts by volume: dishes, bowls, Tian, know-door, balusters, furniture, etc.

Only then changing technologies for: shooting, grading, stamping on a crest or trough, casting a slip in a plaster mold (you must use more land than Salernes, unfit for this technique), all these procedures are implemented to achieve the desired shape.

After drying and cooking, the same techniques of enameling and decorating give these products their character, for a life alone or in addition to the other productions that are found in Salerno.
