Bullion Trading LLC Now Stocks the 24K Gold Casting Grains

Experienced jewelers and goldsmiths know that to get the correct Karat, you need pure 24K gold to mix with other alloys. How you mix pure gold with alloys also determine the color you get. Jewelers prefer different coloring on gold alloys. Some alloyed gold appears green, reddish, pink, white, or rose gold depending on the base metal used.

Bullion Trading LLC is now stocking the pure 24K gold casting grains to give our customers a chance to mix and create gold alloys as they wish. This is an excellent opportunity because buying premixed gold grains is not a good idea. Each jewelry caster has his formula for alloyed gold and how he mixes it. Furthermore, if you’re buying the premixed cast grains for a professional to cast, you may end up with the wrong color of the premixed gold grains.

The alloys mixed with casting grains are not expensive. Hence, it is not a good idea to buy them premixed and spend your money on the wrong grain type. The best approach is to buy pure 24K gold grains separately and use a professional to mix them with alloys. 

So, what’s the difference between pure gold casting grains and other forms of gold? Pure gold grains are gold granules purified using advanced technology to achieve 24K or .9999 metal purity levels. This makes gold granules the purest and finest gold. Buyers can use as little or as much as they want to mix with base metals to produce alloyed gold for jewels.

The commonly used based metals include copper, nickel, and zinc. Mixing gold grains with definite amounts of base metals enables you to develop alloys with the needed characteristics. For instance, some gold alloys resist scratching, tarnishing, or discoloring.

Some dealers sell alloyed cast grains. They may appear convenient, but you may end up with the wrong product that is difficult to smelt. This’s why most jewelers and machinists prefer purchasing gold casting grains and master alloys separately to maximize flexibility.

Buying white gold casting grains and a white-colored master alloy separately is beneficial. It allows you to mix and make white gold items or pure gold items from the grains. Gold alloys exhibit the properties of the metals that constitute them. For example, if you mix two parts of silver with pure 24K gold, the result will be 22K gold or an alloy with a metal fineness of .9167.

100% gold is soft and cannot be used in casting jewelry. Alloyed gold is harder, malleable, and can be beaten into shapes. This makes it perfect for jewelry and making gold items.

The 24K Yellow Gold Casting Grains

Gold grains are unlike other forms of gold. They come in grains with irregular shapes. Gold granules are the purest gold with a finer level of .9999 or 24K. These grains give jewelers and goldsmiths flexibility. They have the option of buying casting grains and then mixing them with master alloys to produce the type of gold they want. Moreover, gold granules can be smelted and used to produce pure gold items.

Casting gold granules requires a temperature above 100°F (37.7°C). Higher temperatures are necessary if the casting is complicated. Experts recommend using small flux when melting with open flames. Pure gold at 24K is very soft to make jewelry. It’s the reason the pure gold is alloyed with other metals to make it hard and resistant to wear and tear. Silver, copper, nickel, and zinc are the commonly used metal to alloy gold.

The type of master alloy used determines the color of the gold cast. For instance, some casts appear yellow, red, green, or white. Alloys of gold-silver-copper look light green-white, green, or yellow depending on the amounts of the base metals used. You can also obtain green or yellowish-green colored gold by mixing big amounts of zinc (approximately 18%) with gold, copper, and small quantities of silver.

Jewelers prefer working with white gold as the latest fashion trend because it resembles the color of platinum. The bluish-white color seen in white gold is determined by the amount of nickel and zinc in the piece. The amounts of nickel in white golds range from 12% to 17%, while zinc constitutes between %4 and 8%. Some white gold alloys in the market are mixed with palladium, making them malleable and a luster resembling platinum.  

Palladium is costly as a master alloy, which limits its use in producing white gold. Cadmium is once in a while added to yellow gold as a base metal. Some years back, the aluminum gold alloy was introduced. This alloy was lightweight and malleable, giving the jeweler flexibility. However, production was stopped because aluminum was causing casting difficulties. The presence of aluminum oxide in small quantities made it difficult to polish the alloy.

When mixing gold granules with base metal, it’s important to use the purest form of the base metal to avoid contamination. Pure forms of base metal include electrolytic copper, Mond process nickel pellets, and Bunker Hill grade zinc which is .9999 pure. Bullion Trading LLC now stocks the 24K gold casting grains.
