History Edit

The science of chemistry was very crude during the Middle Ages and devoted almost entirely to finding ways to convert base metals into gold. This study was called alchemy and practitioners were called alchemists. Alchemists occasionally stumbled upon useful chemicals by accident. The most significant result of chemistry experiments was the European acquisition of gunpowder, which had been invented many centuries earlier by the Chinese.
