Ornamental deals Vase in Raku ceramics

Ornamental vase in Raku ceramic, shaped like a spring with iridescent colours on a copper base.
To maintain the brightness of the colors it is advisable to wax the object two/three times a year. Do not spray directly onto the spray object of any kind, perfume or lacquer.
The procedure for making ceramics according to the technique "Raku", deals in short, is the following: The object is molded by hand or with the lathe. The material of the dough must be refractory, that is, resistant to temperature fluctuations. While the first cooking is done in a traditional way, the second is made in special ovens, from which, once the melting temperature of the enamels (900 °) is reached, the "biscuit" is extracted, with special pliers, and placed to cool in containers , hermetically sealed, containing dried leaves, grass, sawdust or paper. The pieces, still incandescent, cause the combustion of the materials contained in the container, forming within the same a reducing atmosphere, which contributes to produce a series of characteristic effects on the surface of the enamels and on the clay ; During this phase the Craquelé effect of the enamel is created.
To obtain the formation of lustres and reflections, a chemical reaction of the metallic oxides present in the enamels and the clay is first created, then, by immersing the piece in the water, the obtained effect is consolidated.
All these operations must be carried out very quickly and allow, giving free rein to the imagination and creativity, to practice countless variants to the procedure indicated, obtaining increasingly different and particular effects.
