Description

This high-quality .925 sterling silver casting grain ensures excellent results for silver jewelry applications and in virtually any casting method, with a bright white finished metal. The silver and copper that are used to produce the alloy are kept in an oxygen-reduced atmosphere during the melting and pouring process to ensure optimum deoxidation. 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.

Please Note: • For more information regarding the use or composition of this material, please refer to the reference sheet provided below.
• 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.

How To Determine Metal Weight for Wax Trees: Knowing how to determine the correct metal weight for each wax tree before you cast ensures that you melt the right amount of metal for your cast, making your casting process more cost-effective and more reliable.

SPECIFIC GRAVITIES:

24KY = 19.32

18KY = 15.5814KY = 13.07

10KY = 11.57

Fine silver = 10.49

Sterling = 10.36

Platinum = 21.54

Caster's brass chunks = 8.4

Caster's white bronze chunks = 8.1

Ancient bronze = 8.8Yellow bronze = 8.4

Manganese bronze = 8.3

Nickel silver = 8.8

Alpaca = 8.6

Step 1 First, weigh your wax models along with main and gate sprues. Then add an additional 10% to account for your button.

Step 2 Multiply that total by the specific gravity of the metal you're casting (see table above for a general guideline).

Example: For a 5-gram wax model, add 0.5 (10% of 5g) to get a total wax weight of 5.5g. For a 14KY gold casting, multiply 5.5g x 13.07 s.g. The amount of 14KY gold needed for this tree is 71.89 grams.^
