The term "conflict diamonds" refers to the diamond rough used to fund violent criminal insurgencies in several African countries. The Kimberley Accord is a compact that regulates the sale and transfer of diamond rough to prevent the human destruction that conflict diamonds cause. Rio Grande has long asked our suppliers to provide documentation proving the safe origin of the diamonds we buy. You can be assured every diamond you buy from Rio Grande is certified “conflict-free” by both our strict standards and the Kimberley Accord.
This sterling silver anti-firescale grain is a great choice for all types of casting, especially in creating components, sheet or tube that will be formed or connected using soldered joins. It incorporates select deoxidizing elements that prevent the castings from developing firescale when they’re annealed and soldered. Castings are clean and easy to finish. The sterling silver formulation is approximately 90% as hard as traditional sterling silver, and it can be used with acid-based plating solutions. Casting metal, because it comes ready to melt and pour into your mold, is fast and efficient to use and, because it is professionally produced, you can count on consistent, repeatable quality and composition over time.
Sold by the troy ounce (ozt.).
please note:
• Do not use this grain with any cyanide-based plating solution.
• For more information regarding the use or composition of this material, please refer to the reference sheet under the "More Info" tab.
• IMPORTANT: Sterling silver is an alloy containing metals that react with chemicals found in air and produce tarnish; high moisture levels, exposure to sunlight and contaminants such as salt water increase this reaction. Take steps to protect your sterling silver by keeping it in airtight packages, use tarnish-resistant products (such as tarnish tabs or strips) that absorb harmful chemicals, and store metals in a cool, dry place. Most tarnish is easily removed by polishing with a mild abrasive or soaking in an anti-tarnish solution.
