I come in many colors. Although I have a cubic crystal stucture, I tend to break into octahedrons. It might surprise you that I have weak fluorescence. What am I?

My name stems from the Latin word fluere meaning to flow in reference to my low melting point and use as a flux in the smelting of metals.
