Question

Why does flux growth work for making large gems?

a. flux has a higher melting point, so the gem material crystallizes inside cavities in the hardened flux. Just like hydrotheral deposits in geodes.

b. Crytalline material is slowly pulled out of the molten flux by growing it on a "seed crystal"

c. The flux has a lower melting point (tempurature) than the gem material

d. Gem material is soluble in acid so that it can be removed from the platinum crucible

e. gem material acts as a catalyst that alows the flux to melt away, leaving the crystals

Explanation / Answer

Answer: a. flux has a higher melting point, so the gem material crystallizes inside cavities in the hardened flux. Just like hydrotheral deposits in geodes.
