# When fluorite is exposed to ultraviolet light, does it melt?

Not to my knowledge....

#### Explanation:

It certainly glows under UV light. See this site.

Of course fluorite is the mineral form of $C a {F}_{2}$...

No. Melting is a temperature related effect.

#### Explanation:

Melting is a change of state from solid to liquid as a result of increased temperature. Fluorite has a melting point above 1500 degrees C, so simply illuminating it with UV light will not cause "melting" at all.
