名稱   鉬鉛礦	Name   Wulfenite
化學公式   PbMoO4	Chemical Formula   PbMoO4
莫氏硬度   3	Mohs scale of Hardness   3
描述   鉬鉛礦一般結晶成為帶有斜面的方形薄板，具有油脂光澤或金剛光澤，顏色為黃到橙紅色或褐色。發紅顏色是由於其中含有鎢的成分。鉬鉛礦的橘紅色特別艷麗奪目，這種晶體在晶型和組合形態方面不是強項，但強勁火烈的色彩彌補了形態的不足。	Description   Wulfenite is most often found as thin tabular crystals with a bright orange-red to yellow-orange colour, sometimes brown, although the colour can be highly variable. In its yellow form it is sometimes called “yellow lead ore”.
小挑戰   我們可以找到這石頭？ 釩鉛礦是工業上提鍊金屬釩的主要礦物原料，通過對它們進行焙燒和熔煉能將釩元素從礦石中提取出來。偶爾也用於鉛的提煉。	Challenge   What is the function of this stone? Wulfenite is a very popular and highly sought-after mineral by collectors. It is used as a minor ore of lead and molybdenum.
