LeachGarner LG422 Anti-Tarnish Sterling Silver Sheet is a low-tarnish, fire-scale-resistant sterling silver alloy milled by LeachGarner, the leading mill house in the United States. Brighter and harder than traditional sterling silver, LG422 contains germanium, which forms a protective oxide on the surface to resist tarnishing and fire scale — meaning your work cleans up faster and stays bright and shiny longer. This alloy is compatible with both traditional silver and argentium silver solders.
Sheet is sold by the inch and priced per 6" × 1" piece. Otto Frei cuts to order in full-inch increments along the 6" width, from a minimum of 6" × 1" up to the maximum sheet size of 6" × 12". To order a 6" × 6" continuous piece, add a quantity of 6 to your cart. To specify multiple cut sizes of the same gauge, order the total number of inches and include cutting instructions in the comment field at checkout.
All Anti-Tarnish LG422 sterling silver sheet ships in ½ hard temper (Vickers Hardness 105–118). Dead soft or annealed LG422 has a Vickers Hardness of 60–70. The sheet can be annealed easily with a torch or kiln to achieve dead soft temper.
Annealing Note: Heat the metal to a glowing pink or dull red color using a steady, even flame — a darkened room helps you see the color change accurately. This alloy contains germanium; if heated insufficiently before quenching, it may crack. Allow the piece to air cool until the glow is no longer visible with lights on (a slight glow may remain with lights off), then water quench.
