Strata 14K White and Argentium® Mokume Gane Sheet (103-505) Technical Bulletin Nominal Composition: 34% 14K Palladium White Gold, 66% Argentium Silver by weight/mass. Description: This product was developed to take advantage of the special properties of Argentium Silver. The dark grey/white color combination is very clear, and its warm neutral color goes well with many stones (especially ) and high-karat accents. Argentium does not form fire-scale and work hardens much more slowly than sterling, making it ideal for use in highly wrought items subject to multiple cycles. When combined with 14KPW gold the resulting mokume-gane sheet will not discolor with heat and will be very slow to tarnish Pattern: The “Strata” pattern is made from “Everbright” stock. It is a fine pattern best described as a set of irregular lines running parallel to the long edge of the sheet. Uses: Jewelry and other fine metalwork including flatware, hollowware and other decorative metalwork. The component metals are not normally toxic or irritating when in contact with skin, food or drink. : Starts to melt at about 765°C (1,410°F), the meting point of Argentium. Nominal : 6.23 troz/cuin or 11.82 gr/cc. This figure is for estimation purposes only, as actual composition may vary slightly. Quality Mark: No existing category in the current quality marking system.

This mokume is easily formed by raising, cold forming, die striking and sawing. This sheet will work harden quite slowly, making it ideal for deep drawing and forging operations. Work should be annealed after a 40% to 50% reduction has been achieved. Use a that flows at a temperature lower than the melting point. We recommend using Argentium solder. Pressure or stress on this material while it is hot is not recommended as the Argentium is somewhat brittle when hot. Extensive stock removal is not recommended on the patterned side of the sheet, as it will change the pattern or remove it entirely. Annealing: The Argentium is highly reflective at the annealing temperature, so reading the color can be difficult. The use of a flux indicator is recommended. To do this, brush a little flux on the surface and heat evenly until the flux melts. Remove the heat source and cool until the flux solidifies; then quench in water. The recommended annealing temperature is 620° C (1150°F). This material may be torch or kiln annealed. A reducing or carbon-rich heating atmosphere may darken the Argentium surface. Stains may be removed by pickling as per standard sterling. Over annealing in frequency, time or temperature is not recommended. Over annealing can cause excessive grain growth and significantly weaken the , though Argentium is less prone to this than . Finishing: This mokume may be finished using standard jewelry finishing techniques. Filing, cutting or grinding will create “drag- over,” and this should be removed with fine abrasives before final finishing. Heavy buffing is not recommended, as this may smear the surface of the metal and muddy the pattern. A matte or finely textured surface will best show off the colors of the metals in the mokume. Sandblasting or glass beading can produce interesting results; experimentation with surface finish is recommended before determining a final form. Etching: Etching may be done with or reverse in a silver . Be careful not to over-etch; experimentation is encouraged. Patina: 14KPW gold is resistant to most patina . Argentium may be colored with Liver of , though the action is somewhat slower than on sterling.
