Bronze Age
Bronze Age cultures differed in their development of the first writing. According to archaeological evidence, cultures in Mesopotamia (cuneiform script) and Egypt (hieroglyphs) developed the earliest viable writing systems.
The overall period is characterized by widespread use of bronze, though the place and time of the introduction and development of bronze technology were not universally synchronous. Human-made tin bronze technology requires set production techniques. Tin must be mined (mainly as the tin ore cassiterite) and smelted separately, then added to molten copper to make bronze alloy. The Bronze Age was a time of extensive use of metals and of developing trade networks (See "Tin sources and trade in ancient times"). A 2013 report suggests that the earliest tin-alloy bronze dates to the mid-5th millennium BC in a Vinča culture site in Pločnik (Serbia), although this culture is not conventionally considered part of the Bronze Age. The dating of the foil has been disputed.
Spurlock Museum
This collection of approximately 1750 inscribed tablets from ancient sites of Umman and Drehem in Mesopotamia dates from the Third Dynasty of Ur in the 21st and 20th centuries BCE to the Neo-Babylonian and early Persian periods(ca. 625-520 BCE). This collection includes texts written in both the Sumerian and the Akkadian languages. The script called cuneiform, is the earliest writing system in the world.
