Bearing Piece
a loop of wire or tubing that supports the stone on certain prong settings. The prongs attach to the bearing in some way.

Burnishing Tool
a tool with a smooth, slightly curved end a bluntly pointed tip. Used for setting stones and rubbing metal to make it smooth.

Cabochon
a round or oval convex stone, usually flat on the bottom side. It's polished but not faceted.

Charcoal Block
specially prepared charcoal compressed into a block. It's used to support metal during the soldering process since pins or wire can be pressed into it. The charcoal reflects and absorbs the heat from the torch to increase the temperature directed at the metal.

Fabrication
the process of creating a piece by hand

Facet
small, geometric planes cut into a stone. Faceted stones have facets cut at an angle that bounces light around within the stone and out of the top of the stone.

Filing
process of removing small amounts of metal using a metal file.

Fine Silver
contains less copper than sterling silver, this gives it a lower melting point.

Flux
a paste or liquid mixture of borax used to prevent metal from oxidizing during soldering. This allows the solder to adhere to the metal. Flux must be applied to all joints before soldering.

Gauge
refers to the thickness of the metal and is described by numbers. One gauge is equal to 0.0074 inch. The larger the gauge the thicker the metal so a gauge of 12 is much thicker than a gauge of 22. Both wire and sheet metal are measured by gauges.

Mohs Hardness
A scale of durability created by Friedrich Mohs a German mineralogist. The scale is graded from 1 - talc (the softest) to 10 - diamond (the hardest).

Oxidizing
the darkening of the surface of metal, prevents solder from adhering.

Pickle
A weak acid that removes oxidation.

Rifle File
Oddly shaped files that allow the filing of oddly positioned metal pieces.

Silver Solder
an alloy consisting of silver, zinc and copper. It's used to join two pieces of silver, brass, bronze, nickel or copper. Solder comes in hard, medium and easy with hard solder having the highest melting point and easy the lowest. The more zinc in the solder the lower the melting point.

Soldering
process of joining two pieces of metal together using solder

Yellow Ocher
an oxide that forms a paste when mixed with water. When applied to soldered joints it prevents them from remelting.
