Identification of bronze artifacts from the late bronze age and ritual folded swords from the hellenistic era - from accidental finds to hamburg-marmstorf

The ancient metal products preserved to this day are those made of gold, silver, copper, bronze and iron. While precious metal objects arouse particular interest because of their exceptional jewelry and technological value, bronze objects prove to be a mystery that has greatly influenced the development of corrosion resistant technologies in the everyday life of mankind, Jotsova (2012). Only slight differences in the chemical composition of the alloy, composed of the two metals copper and tin, can change both the color of the object (from yellow-gold, at 6 to 18 wt.% Tin, to shiny silver at contents, above 18 wt.% Tin) and a number its mechanical properties such as malleability, hardness, etc., Scott, Podany, Considine (1994); Черных (1978) .
