If a mineral is earthy, silky, waxy, or metallic, you are describing this.
What is its luster?
300
A substance that did not arise from something that was once living.
What is inorganic?

Name three ways to identify the difference of gold and pyrite.
What is a density test where gold is more dense, a streak test where gold would have a gold streak and pyrite would have a black streak, and an acid test where gold would have no reaction and pyrite would?
500
This is made during the process of extracting iron, when impurities in iron ore and limestone combine, be put in a blast furnace and the iron in the iron ore has melted and sunk to the bottom of the furnace.
