“Our pupils shall not simulate lights and shadows, or represent the relief in any way, yet, but only colour the various parts of their interweaving, so that they may become acquainted with the intelligence of standard colour in the various industrial arts.”

*Original Language: „Gli alunni nostri non devono ancora né simulare la luce e l’ombra, né rappresentare in nessuna maniera il rilievo, ma solo tinteggiare le varie parti de‘ loro intrecciamenti per iniziarsi alla intelligenza del colore convenzionale nelle varie arti industriali.“ (Boito 1897)

“The manufacture of ceramic pieces is not only a profession, but also an art. This image shows the watercolor reinterpretation of a design type. The manufacture of these tiles in the traditional way, is not complicated but special tools are needed for their composition and modeling and an oven to achieve the rigidity of the tile.” (Agata)

“Ceramic production is a process where clay is turned into an artificial stone trough burning.
This requires several steeps, which all need educated staff.
The process can be broken down into two main steeps, which are:
1. Producing the actual ware (tile), through burning clay, also called earthenware.
2. The decoration of the good, which also gives the typical surface. The earthenware is glazed, painted and then burned two more times.” (Marie)

“Painting by hand or using a pounce, painters could apply the pattern with charcoal on several objects. The blue pigment “cobalt oxide” was mined in Germany, the purer the cobalt, the brighter the colour would be. While painting the oxide is dark grey, after the next fi ring this would change and the typical blue appears.
If some extra gloss is wished, an extra layer of transparent lead glaze can be added in this step. (kwaarten)”. (Marie)

“After processing the clay the tiles can be formed. Two wooden slats help creating an evenly height throughout the tile by rolling with a round piece of wood. Cutting the size of the tile afterwards by using a knife. Because of the thin height a very slow an even drying with flipping the tiles is required.” (Alina)

The dried tiles can then be burned for the first time. The chemically bound, crystal water is driven out; the clay loses its plastic property and becomes waterproof. The burning temperature is up to 1000 -1200 degree. A result is weight reduction and an increase in porosity. (Alina)
