The first observations of fluorine came from the 1500s , with a German mineralogist who described it as a material that served to lower the melting point of ore. In 1670 , a glassworker accidentally found that fluorspar and acids would react and used the reaction to etch glass .
16世纪一位德国矿物学家开始研究氟，并把它描述为一种能降低矿石熔点的物质。1670年，一个玻璃厂工人偶然发现氟石和酸性物质能够发生化学反应，并将这一发现用于蚀刻玻璃。
