Metallurgy (Civ3)/Civilopedia

Metallurgy is the study of the properties of metals and the methods used to separate metal deposits from metal-bearing ores. Through the 
course of history, artisans have switched the materials from which they constructed weapons and tools to harder, more durable metals as they 
were discovered. However, metallurgy as a science wasn't studied in earnest until the powers of Europe began to compete against one 
another in an attempt to design better and more effective weapons starting around the 14th century. Constant improvements in metallurgy led 
to the discovery of new metals and alloys that were stronger, lighter, and cheaper. As a result of this race for military dominance, Europeans 
produced some of the most advanced weaponry in the world during this time period.
