Although drums do not contain a lot of steel, metals are essential for a lot of music instruments, most notably for wind instruments. For instance, most trumpets are made of brass with 70% copper and 30% zinc, but silver and even gold trumpets are sometimes created for special occasions. Also, strings on a guitar for example, might be made of metals. The metal that is used for the string influences the tone and steel strings are known to give bright tones, whereas nickel gives a warm sound and chrome is usually preferred by jazz and blues artists.

Trakai Castle

The principal construction material of Trakai castle is typical red Gothic brick. The major advancement in brick making was burning the clay in a kiln instead of letting the clay dry in the sun and this process was introduced on big scale by the Romans. The typical red brick that can found in buildings all over northern Europe was reintroduced in the 12th century.
