Forming and firing

We note here that these sketches of the history of cerarrries before the 19 century focus especially on pottery itself. To review all the techniques of manufacture, assembly and shaping that were bom out of terra eotta arts, we must also take into accormt all the other types of productions floor tiles, architectural elements, more important statuettes and scrrlptures, various artifacts, etc. The scope of this book does not allow us to delve into this subject in detail. 

This know-how and these techniques would unleash creative imagination through the milleimia, to the four comers of the world a universe burgeoning with shapes and decors. The shapes, from the simple useful object to the prestigious work of art, are itmumerable, so varied from one culture to another. As for decorations, for reasons of accuracy, we will now present the techniques of the most characteristic and most universal decorations. 

As early as the first potteries, decoration was immediately an essential element, a symbolic system with which a whole culture identified itself. The simplest shapes are incisions, nail marks, scratches, etc. An example taken from the old Neolithic era [MOH 98] will illustrate the importance of the study of decoration in the knowledge of cultmes. Along the Mediterranean, around 6,000 BC, ceramics with cardial decorations flourished we can trace the expansion of the culture between 5,000 and 4,500 BC towards the Massif Central and the Atlantic coasts by discovering the presence of ceramics in the excavated sites. 

At the same time, in Central Enrope, aronnd 4,750 BC, another cnltuie developed, that of ceramics with linear decoration, where the decorations are ribbons, volntes, horseshoes, etc. covering the Dannbe valley and the Rhine valley. 

in the West, the civilization of megaliths would develop, characterized, as regards ceramics, by shapes that are not decorated or with a few gripping buttons.

Clay makes an excellent material for didjeridus. Although fired clay is rigid, and even brittle, compared to other materials like wood it is also very resonant and has some unique acoustical properties that work well-suited to didjeridu playing. I use stoneware clay that is best suited to sculpting large forms and fire it to cone 10 , about 2400 degrees Fahrenheit. This produces a vitrified, hard, dense and durable instrument with exceptional resonant qualities. 

Fused quartz or silica tubes are used as insulators through which the wires of a rare-metal couple are threaded, and as outer protecting tubes. The molten quartz may be drawn and worked like glass or the material may be ground and pressed, with a suitable binder, into the proper form and fired in a manner similar to that employed for the manufacture of porcelain. These tubes are translucent like china. Trans-...

The bonded abrasive article, after it is formed and fired, may still be incomplete or unusable in that state. The use of adhesive materials to bond such articles together or to other materials is common, and a wide variety of adhesive systems have been used.
