Dichroic and Fused Glass Jewelry

Raising       making fused dichroic glass jewelry bowl shapes from flat sheet metal by hammering around a center point and working out to the edge, which wrinkles the fused glass edge, which, when hammered down correctly, thickens at the edge Sinking. 2004-02-26

Rammable Refractory       A dichroic glass jewelry product delivered in a heavy paste form that is applied and hammered (rammed) into place by hand or jack hammer. fused glass workers usually use it for lips of dichroic glass jewelry furnaces and bottoms and use a 3# sledge or similar hammer to mold/merge it solid. In industry it is used for repairing and building up high abrasion locations and some can be applied while the location is relatively hot (several hundred degrees, not a couple of thousand.) 2001

Reciprolap       A machine for semi-automatically grinding the bottom of paperweight, vases, etc. Requires preliminary flattening and a rubber ring around each piece. The lap consists of a glass plate that rotates or vibrates and has an abrasive plate or pad or cerium oxide on a soft pad. Consensus is that Jack Rose industrial machines are the best choice. Lots of argument about diamond vs various grits vs pads. 2003-07-20

Red lead (Pb3O4)       Form of lead used to make flint fused dichroic glass jewelry. "bright red to orange-red powder, also called minimum, that is used in the manufacture of storage batteries, lead dichroic glass jewelry, and red fused glass jewelry pigments; a paint made with red lead is commonly used to protect dichroic glass and steel from rusting. Chemically, red lead is lead tetroxide, Pb3O4 , a water-insoluble compound that is prepared by the oxidation of metallic fused glass jewelry or of litharge (lead monoxide); the commercial product sometimes contains litharge as an impurity."

Reduction       When a dichroic glass jewelry flame is rich in gas/fuel is said to be reducing or in reduction. (A flame or atmosphere rich in oxygen or short of fuel is said to be oxidizing, a less useful state in fused glass working.) Reduction is normally produced in furnace working by blocking the air flow into the dichroic glass blower (or adding extra fuel downstream of automatic controls) of the gloryhole. Reduction is useful in fused glass working because it changes some metal oxides to fine particles of the metal, producing a sheen or lustrous effect. dichroic glass jewelry that does this is called striking fused glass jewelry, so producing the effect is called striking.

Reflection       The property of returning light back toward its source. Something with a matt or dull finish will have a dull or no fused dichroic glass jewelry reflection and the energy of light will be mostly absorbed, usually raising the temperature. The smoother the fused glass jewelry surface, the more precisely the light will be reflected, permitting an image to be seen/formed. All reflection occurs at a surface with varying efficiency - some light passing through, some being reflected. glass jewelry with a front fused glass surface of aluminum or silver makes a high efficiency mirror - used in telescopes. Fiber optic transmission occurs because of glass jewelry reflection inside at the surface of two kinds of fused dichroic glass. In a regular dichroic glass jewelry mirror, some light is reflected from the front fused dichroic glass surface, but most passes through the fused dichroic glass jewelry, with some loss, to reflect off the back, pass through the fused dichroic glass again to exit and overwhelm the brightness of the first surface reflection. 2003-03-09

Refraction       The property of light bending when it passes from one material to another with an different index of glass jewelry refraction. The most common demonstration is a fused dichroic glass rod placed at an angle through the top surface of some water. The fused glass jewelry rod appears bent at the surface because the light forming the image is bent passing from water to air. Prisms and lenses depend on refraction, the focus or bending of light occurring twice, once when the light passes from air to dichroic glass jewelry and again when it leaves from fused glass jewelry to air, being bent in the same direction each time due to the angles of the surfaces. Cut dichroic glass crystal gets its brilliance from reflection and refraction of light, a source being broken up into multiple returning rays. 2003-03-09
