How Gold-Filled Metals Are Made
Gold-filled, or gold overlay, is made by heat- and pressure-bonding a thin layer of karat gold to a brass (or other base metal) core. The "14/20" or "12/10" notation refers to the industry shorthand describing the resulting material. The first number is the karat purity of the gold used; the second number is the amount, by weight, of gold to the substrate material. "14/20" gold-filled material is made with 14-karat gold and the gold represents 1/20th (or 5%) of the total weight of the material. You may occasionally see other notations, too; each will inform you about the material's make-up. For example, "14/40" gold-filled is composed of 14-karat gold that represents 1/40th (or 2.5%) of the overall weight of the material.
• Karat gold covers the brass surface, making it tarnish-resistant.
• The value of gold-filled is greater than gold-plated because gold-filled has an actual layer of karat gold, not just a microscopic film.
• All of Rio’s gold-filled products meet federal quality standards.
• Gold-filled jewelry is economical. Your customers enjoy the warm tones of gold at a fraction of the cost of pure gold.
• In 14/20 gold-filled, 1/20th (or 5%) of the total weight of the metal is 14-karat gold.
• In single-clad sheet, the gold layer is bonded to one side of the sheet of brass.
• In double-clad sheet, discs and other findings, the bonded gold is distributed to both sides of the brass (or base metal) sheet. In findings, the same amount of gold is distributed so as to cover all sides of the finding. This means that the thickness of the gold layer on each side will be half what it would be on single-clad sheet.
PLEASE NOTE: The weight of the gold relative to the substrate (brass or other base metal) will be the same in both single-clad and double-clad; on the single-clad sheet, all the gold is bonded to one side and, on the double-clad sheet, the gold is distributed so that half is bonded to one side and half to the other side. It is possible to manufacture double-clad gold-filled sheet so that both sides have the same thickness as a 1/20th single-clad sheet; in this case, the material would be 1/10 (10% by weight) of whatever karat gold is used--14/10 for example.
How To Prepare Dead-Soft Wire For Use
Before you begin designing with dead-soft wire, make sure the wire is as smooth and kink-free as possible. Here's how to prepare dead-soft wire for use to ensure a smoother result in your designs.
Pull your wire through a polishing cloth to smooth out the tiny kinks and wrinkles. Please Note: This process can also work-harden your wire, so easy does it!
If you are preparing three or four wires, pull each wire through once, then pull all of them through together once. They will flow in the same direction and will be much easier to sculpt.
How To Protect Your Gold-Filled Material
Handling your gold-filled properly is essential to maintaining its good looks and its bright finish. Made with a substantial layer of gold bonded to a base metal core, gold-filled requires some special care to keep the gold layer intact and unmarred for your designs.
If handled properly, gold-filled should require only buffing. If you cut it, be careful not to damage the gold layer, particularly on corners and edges.
Gold-filled stock should be stored in a dry place. Tarnishing elements act very slowly in the absence of moisture.
Use tissue paper between stock to protect it against scratches.
Use a clean flannel cloth while working on gold-filled material.
Maintaining the condition of your tools is important. Keep cutters sharp; bending tools should be smooth.
Use a firescale retardant such as Stop-Ox II™ when soldering.
Clean the metal thoroughly.
