Karating Up and Down Conversions
To figure out how much gold you should add to karat up:
Take your starting weight and figure exactly how much alloy is contained. Divide this weight by the alloy factor of the karat you want to go up to. This will give you the total weight of the desired karat that you will end up with. Subtract from this total weight your starting weight, and this will you you much fine gold to add.
Example, 10K to 14K: | |
Starting Weight 10K | 350 T/oz |
x .5833 | |
Total oz. alloy contained | 204.155 |
Divide by | .41667 |
Total amount of 14K made with this amount of alloy | 489.97 T/oz |
Subtract starting weight | -350.00 |
Amount of fine gold to be added | 139.97 T/oz |
To figure out how much gold you should add to karat down:
Take your starting weight and figure exactly how much fine gold is contained. Divide this number by the gold factor of the karat you want to go down to. This will give you the total weight of the desired karat that you will end up with. Subtract your starting weight from this number, and that will tell you how much alloy to add.
Example, 14K to 10K: | |
Starting Weight 14K | 500.00 T/oz |
x .5833 | |
Total fine gold contained | 291.65 T/oz |
Divide by | .41667 |
Total amount of 10K made with this amount of fine gold | 699.95 T/oz |
Subtract starting weight | -500.00 |
Amount of alloy to be added | 199.95 T/oz |
Simple Conversion Factor to Karat Up or Down
Reducing Factors
To reduce karat: Find reducing factor at intersection of “Karat on Hand” and “Karat Wanted. Multiply the weight of your karat gold on hand by the reducing factor. This gives you the weight of alloy you must add to reduce to karat wanted.
