Flux

Flux healing
When flux fills a fracture, it dissolves the wall of the fracture until that small amount of liquid in the crack becomes saturated with sapphire solute.

When the molten flux mixture cools, the synthetic corundum will permanently fuse the crack together, but the process will leave behind small air pockets surrounded by solidified glass (above, right).

Flux-melt technique
Flux remnants in a flux-grown synthetic ruby.
This is a high quality gemstone synthesis technique rarely used in fashion jewelry or industrial applications due to higher production costs.

Flux grown:
This is the synthetic variety that you can not easily distinguish from a real one. Molten flux is crystallized under specified conditions of temperature and pressure to produce these versions of synthetic rubies.

FLUX. To melt, to fuse. As a noun, a fluid or substance which may be used to fuse some other material.
FRACTURE. Breaking a gem otherwise than the lines of cleavage.
GEM COLOUR. The most desirable colour for a stone.

flux - a substance used to promote fusion by preventing oxidation at the point of soldering, thus enabling the solder to flow. When soldering gold and silver, a solution of borax or "self-pickling flux" is used.

2) Flux: In some cases the solvent in which the gem source materials are dissolved is not water, but another material like lead fluoride or boron oxide, called a .

flux - A chemical composition used to enable solder to flow when it melts by preventing oxides from forming when metal is heated during soldering.

Flux Healing: The flux healing method of enhancement is used to repair surface cracks, inclusions or cavities that may be present in a ruby.

The flux is present to melt impurities in the ore, principally silicon dioxide sand and other silicates. Common fluxes include limestone (principally calcium carbonate) and dolomite (magnesium carbonate).

We make our own flux, but there are good ones on the market. If you want to make your own, this is the formula. Get the ingredients at your local drug store. 90 grams boric acid, 60 grams borax, one qt. distilled water.

Comments: Fluorite, calcium fluoride, is a major industrial mineral used as a flux in steel making as well as in the preparation of hydrofluoric acid and, in the ceramics industry, in glasses and enamels.

Flux-grown synthetic rubies manufactured by J.O. Crystal Company ("Ramaura Ruby"), Chatham, and others are considerably more expensive. They are sold in 4, inclusion-based, grades (Gem, Fine, A, B) and several size (weight) categories.

A mineral is crushed and mixed into a borax flux, and is heated until a glassy bead forms. The bead is then touched by the crushed mineral powder and one of several colors appears on the bead, depending on the metallic elements of the mineral.

The name fluorite comes from the Latin fluo "(flow") in reference to its use as a flux.

It was first produced accidentally in experiments to produce a synthetic sapphire by the Verneuil Furnace process and using cobalt oxide and also magnesium oxide as a flux. It can be made now to imitate gemstones of several other species, e.g.

Heating ore or concentrate material with suitable flux materials at high temperatures creating a fusion of these materials to produce a melt consisting of two layers with a slag of the flux and gangue (waste) minerals on top and molten impure metals ...

Enamel - Low fired over glaze ceramic pigments derived from metallic oxides such as copper, gold, manganese, iron or antimony used singly or combined with an opaque white and lead, zinc or some special flux, ...

Enamel is the fusion between a special powdered glass that is allochromatic and usually consists of quartz sand, iron oxide, potassium oxide (pot ash) and borax (flux).

Other methods of growing synthetic corundum, such as flux-grown, Czochralski pulled, and hydrothermal methods, produce more realistic imitations, which are primarily identified by characteristic inclusions.

Solution techniques for making synthetic gems include flux methods for emerald, ruby, sapphire, spinel, YAG, GGG, and alexandrite.

One way to prevent fire scale is to coat the entire piece you are working on with flux. As the flux dries when you are soldering, it will create a glass that forms a barrier between the copper and the oxygen.

From the Latin "fluere", meaning" to flow". It was used in ancient times as a flux. Contact with sulfuric acid releases HF gas (very toxic!) Often fluorescent in UV.

This purplish - black sapphire from Burma is transformed into commercially usable pink sapphire after a flux additive is put in the heating process. Traditional heating of sapphires typically takes 2-3 days.

The word fluorite originated from the use of the mineral as a flux in steel and aluminum processing. Actually fluorite was referred to as fluorspar by the miners and is still famous today by that name.

Gemstone Uses: Rubies are commonly subjected to enhancements such as heat-treating, fracture-filling, and flux-healing to improve colour and repair both fractures and inclusions.

Joining metals by filling clean joints with a suitable filler metal. Temperatures are higher than for soldering and a good flux is usually needed.

It's important that metal is clean before it is soldered. Pickle solutions remove oxidation and flux from metals such as silver, gold, and copper. Sparex, sulfuric acid, and nitric acid are all used for pickling solution.

Hematine, an imitation of hematite, is magnetic, whereas most natural hematite is very weakly magnetic. Synthetic diamond can contain iron-nickel flux inclusions and can show magnetism (when floating in a heavy liquid such as Clerici's solution), ...

Used to help people who lack resourcefulness and who have an acute fear of personal failure. Excels in healing emotional and physical aspects of heart/lungs. Also used in as an aggregate for cement and as a flux in blast furnaces.

If you see man-made emeralds you might wonder why they are so costly compared to CZs or some lab created sapphires. Both the flux and the hydrothermal methods of production require costly equipment and are energy intensive.
