Elements and Alloys Chart - CLICK HERE! Courtesy of Tim McCreight ALLOYING Very simply, you work with the percentage of
precious metal you want (refer to the Elements and Alloys chart) 75% equals,
.75 as an example. If you have an EXISTING amount of metal, and WANT
to alloy it, you will DIVIDE the Percentage of Metal, (the Elements and Alloys
chart) by the amount of pure metal you have. Example:
You have 15 grams of pure gold, (24 karat), and want to make it into 18K yellow
gold. Since the Elements and Alloys chart shows that 18K
consists of 75% pure gold, and you have 15 gr of pure gold, 15gr divided by .75
= 20 gr. 20gr is the total amount, including the alloy you will need to add to
make 18K with 15 gr. of pure gold. On your scale, with the 15G of pure gold, add your
alloy metal, until your scale reads 20.0 total. This combination, of Pure Gold
(24K) and Alloy when melted together, will make 20 gr. Of 18K gold. If you need a specific amount of alloyed metal, you
would MULTIPLY the goal amount you want with the percentage of precious metal
in the alloyed metal desired. Example:
you want 30 gr. of 14Kwhite gold. Multiply 30 times (X) the .58 (percentage of
pure gold in 14K) which gives you 17.4. Put 17.4 gr. Of pure gold on the scale,
and add White Gold Alloy to bring the total weight up to 30.0 Gr. which is the
total amount you want. Amount You HAVE DIVIDE by Percent of pure metal in your goal weight. Add Alloy to pure metal to make total total alloyed
amount of metal. Example: have 10 gr 24K gold, want to make 18K yellow
gold, 10/.75 + 13.3 add 3.3 gr of alloy to 10 gr of pure gold to make 13.3 gr
of 18K.yellow gold. Amount You WANT Example: If you want to make 30 gr. Of 14K white gold, then multiply 30 gr. by ..58 = 17.4. Weigh out 17.4 gr. of pure gold, and add white gold alloy to it until you the scale reads 30 gr. You now have 30 gr. of 14K white gold, once melted and stirred together.
