Material Data

Brass
Depending upon mixing proportion the colour varies from gold-orange (with high copper portion) to light yellow. Brass is a little bit harder than pure copper, however not as hard as bronze, a copper-tin alloy. The brass melting is highly liquid and takes up less gases than pure Copper melt, therefore it can be poured low in gas. Remarkable is the Colour similarity to gold. Brass contrary to stealing and aluminium alloys is not hardened through Thermal treatment. The firmness can only be controlled by suitable alloy choice and by mechanical shaping (rollers, smithies or pulling in cold condition)

Ceramic

The designation ceramic originates from old Greek. „Keramos“ it was the name for clay and products resistant to deformation due to burning. The production of ceramic belongs to mankind’s oldest cultural techniques. Their oldest use seem to have taken place with semi established hunting cultures in the upper Nile area. Originally it owes its enormous spreading however to the extended possibilities for the keeping (supply) of food as it became necessary with the Neolithic. Ceramic plays a substantial role in the framework of Determination of Neolithic cultures. However the raw material clay also offered already very early stimulus to artistic composition. For many decades ceramic has attained great importance in technical applications.

Glass
Glass is an amorphous, i.e. essentially not-crystalline substance. Usually glass is produced by melts, the formation of glass is possible by heating up of Sol-Gel and by shock waves. Glass is called thermodynamic as a frozen, under cooled liquid. This definition is valid for all substances, which are melted and accordingly cooled down fast.

Teakwood is a dark-brown heavy hardwood, which is attained by the enormous Teak tree (Indian oak, Tectona grandis L.). Teak is an extremely dense wood (680 kg/m ³) and due to its high natural oil and Indian rubber content resistant to worms, mould fungus and fungal attack, acid-resistant and also hardly inflammable. Therefore it became appreciated in times of wooden ships for shipbuilding, consumption was particularly high in the USA and in England. In the 1950 and 1960 Teak was in particular used as material for internal furniture. Meanwhile the wood finds use mainly in shipbuilding (Ship deck), on terraces and in garden furniture production. Due to the absolute weather resistance this wood is suitable for permanent outside employment (also with constant seawater contact). Teakwood can be well planed, cut and shaped with carbide tipped tools, but due to the mineral existing in the wood these tools become usually blunt fast.

Aluminum (Al)
is the chemical element with the ordinal number 13. The designation leads itself off from the Latin word alumen for alum. In the periodic system of the elements, aluminum belongs to the group of boron, earlier also designated as Group of the earth metals. Aluminum is the third-most frequent element and most frequent metal in the earths crust. There it arises only in chemically bound condition because of its reactive behaviour.
