^ Scheelite (tungstate of calcium) is a 

 very lieavy mineral, which is ordinarily 

 found in veins in crystalline rocks. It 

 is an ore of timgbton^ a metal that is used 



to form an alloy with steel, made for uses 

 requiring great hardness. Tungsten is 

 also employed in making filaments for 

 electric lights.
