2 Ounce Pack-Re-Cast-It Gold Alloy Refresher-Replenisher

Re-Cast-It is an alloy additive used when casting old or scrap gold. Re-Cast-It does not contain gold nor is it designed to substitute for gold. Best results are obtained when mixed with yellow gold.  Sold in a pack of 2 troy ounces (40 Pennyweight)


Cleans old gold castings giving it a bright yellow new gold look
Helps eliminate porosity
Increase fluidity of old metal
Eliminate reddish surface coloration commonly associated with casting old gold

Designed to de-oxidize used gold when casting. You should obtain excellent results by following a few simple instructions printed below.

MIXING:

For 10K Scrap-Add 5 DWT of Re-Cast It and 3.57 DWT of fine gold for each 100 DWT of 10K scrap being melted.

For 14K Scrap-Add 2 DWT of Re-Cast It and 2.82 DWT of fine gold for each 100 DWT of 14K scrap being melted.

For 18K Scrap-Add 1 DWT of Re-Cast It and 3.0 DWT of fine gold for each 100 DWT of 18K scrap being melted.


For white gold, the above ratios can be used but use will be limited to one or two times due to the yellowing of the white color.

If Re-Cast is used with scrap and fresh mixes in continuous re-use, use 1/2 of the amounts listed above.  This will prevent excessive buildup of deoxidizers in the metal.

MELTING:

Place Re-Cast It at the bottom of the crucible when melting, with scrap on top.  When the mixture becomes fluid, stir with a carbon or a quartz rod to clean surface of any oxides produced.  Fluxing may be necessary depending on the condition of the old gold.  We recommend Boric Acid.  Re-Cast It will work best when old metal is clean from heavy surface oxides and investment powder.  If metal is contaminated with cuprous oxide (the red color oxide), only limited positive results can be expected.


NOTE:  Use carbon rods only with gas fired furnace or torch melt.Quartz rods should be used for all electric induction melting.
