  2. ¿ëÁ¦ (Flux)

a. Attempts in late 1800's with commercial development successful in late 1930's and early 1940's.

b. Method

    1) Powdered ingredients mixed with flux in platinum crucible.

    2) May have seed crystal.

    3) Flux has a lower melting point and becomes a powerful solvent for the other ingredients, causing them to melt.

    4) Cooling and evaporation causes crystallization of individual crystal in clusters.

    5) Most natural appearance of the synthetics.

    6) Takes up to one year.

c. Characteristic Inclusions

    1) Flux inclusions in wispy veils, globules, drippy icicles.

    2) Platelets - platinum flakes.

    3) Fingerprints - healed fractures.

    4) Straight growth zoning--indicates gemstone cut from a well-developed single crystal (also occurs in natural gemstones).

    5) Included seed crystals.

d. Materials Synthesized (expensive)

    1) Synthetic corundum.

    2) Synthetic emerald.

    3) Synthetic alexandrite.
