How To

The Difference Between Gold Alloys and Master Alloys

Two terms you should be familiar with are "gold alloy" (sometimes called pre-mixed gold alloy or karated gold, which must contain gold in the amount specified) and "master alloy" (which is an a blend of non-precious metals intended to be mixed with gold.)

1 A gold alloy has a specific amount of gold combined with other elements, such as copper, silver, nickel and zinc. The metals added to gold are called “alloying additions.”

2 The most convenient way to add alloying additions to pure gold (to create a lesser karat value) is to pre-mix the alloying metals into a master alloy that will give the gold alloy specific physical properties such as color, strength and density.

3 When you buy a master alloy, you receive a combination of metals that must first be mixed with pure gold to create your gold casting alloy. All gold casting alloys start with pure 24K gold, which is a brilliant yellow and very soft. The master alloy you choose determines how color and other characteristics change in the final gold alloy. A master alloy labeled “14K rich yellow” will produce a rich yellow 14K gold alloy when it is properly mixed with 24K gold.

4 It is quite possible to raise the karat value of gold that has already been alloyed; however, care must be taken to avoid mixing dissimilar master alloys. Mixing master alloys made with different metals usually results in the loss of the intended properties of either master alloy.

5 Using master alloys gives you the advantage of having a wide range of colors on hand at a low cost compared to stocking several amounts of karat gold. Rio Grande offers a complete range of master alloys you can use to create many colors and karat values of gold—including nickel white and nickel-free palladium white.

6 If you make your own sheet and wire, you can customize your casting alloys to produce the best working properties for your particular needs. This means less cracking as you roll or pull your own metal to your required sizes.

7 If you create your own alloys, (or when you’re ready to begin alloying your own metals) depend on Rio to be your partner in success!

Karating Made Easy

Create the karat value you want using the tables below. For a new alloy, begin with 24-karat (pure gold) and reduce to the karat value you need. If you have a lower-karat alloy already on hand, use the appropriate table to either raise or lower its karat value to meet your needs.

Reducing Factors
	Desired Karat Value
Starting Karat Value	22K	18K	14K	10K
24K	.091	.333	.714	1.40
22K	—	.222	.571	1.20
18K	—	—	.286	.800
14K	—	—	—	.400

Raising Factors
	Desired Karat Value
Starting Karat Value	10K	14K	18K	22K
0K	.714	1.40	3.00	11.0
8K	.143	.600	1.667	7.00
10K	—	.400	1.33	6.00
14K	—	—	.667	4.00
18K	—	—	—	3.00

To calculate your karat weights, multiply the pennyweight of the gold you're working wtih by the factor (from the tables above) for the karat you want to create. See examples below.
To make 14K alloy from 8 dwt. of 24K: 8 × .714 = 5.71 dwt. of alloy.
To make 18K alloy from 15 dwt. of 14K: 15 × .667 = 10 dwt. of 24K.
