Welcome to our April edition of United News. The first quarter is complete and we have seen an increase in the repair base products. Since the gold buying phenomenon has slowed, many of the jewelers are going back to the fundamentals of their business which is selling out of their show cases, repairing jewelry and manufacturing custom pieces.
We bring you this newsletter in hopes of sharing with you some things in the industry that can assist you in your pursuit of business. If you see anything here that brings questions, concerns, or possibilities to your world – please let us know. We are here to serve.

Prealloying Fine Gold & United Master Alloy to Make Karat Gold
The fine gold and master alloy should be weighed on the same scale prior to melting to avoid any weight variations. All calculations and weights should be double checked and balanced against your gold inventory. The weighed gold and master alloy should be put in a clean crucible to be melted. It is helpful to put the master alloy in the bottom of the crucible and the fine gold on top.
In open melting systems, a little boric acid flux can be sprinkled on top of the alloy before loading the gold. In closed melt systems flux is not recommended. Set your melting furnace to the alloying temperature listed on the instruction sheet. You will notice the alloying temperature is higher than the casting temperature as more heat is needed to properly alloy the gold and master alloy before casting. In open melt systems stir, flux and skim the molten metal, stir again before pouring, this will assure a homogeneous mix.
In closed melt systems use the power stir device on your casting machine. The molten karat gold is usually poured in water to make casting grain (shot). If you are hand pouring your karat gold into water, a slow steady pour speed, very close to the surface of the water will give a more rounded shot. Pouring from a height will give a flake like shape.
The karated casting should be dried before using it for casting. The karat casting grain can now be cast at the suggested melt temperature for casting.
Assays should be done periodically to assure the karat of the gold being used. When scrap and fresh mixes are used for casting, we recommend a 50/50 scrap to fresh ratio for yellow gold and a 70/30 mix (70 fresh and 30 scrap) for white gold alloys.

United's 200 Series Alloys for Yellow Gold
While United's spirit of innovation drives us to create new alloys and products, our 200 Series Alloys for Yellow Gold have been a staple in the industry for many years. These original formulations, dating back to United's inception in 1988, have become a permanent part of many jewelry collections for the biggest names in the industry.
If you haven't already, give our #200 alloy a try! United's #200 Alloy provides a beautiful bright yellow tone in 9-14K. Available for casting applications, the #200 Alloy contains low silver, offers high reusability and is designed for open casting systems. If you're working with a closed casting system, try our #204 Alloy which offers the same features and results.
The 200 Series offers various options including color variance, tarnish resistance, De-Ox additives, stone-in-place and more. Contact your sales representative to order a sample from the 200 Series Alloys for Yellow Gold.
Want Karated Grain? Many of our 200 Series Alloys are available in Karated Grain! For additional information on these and more alloys, download our mobile app and browse our product catalog from your mobile device.
Maximizing Your Refining Returns
Ever wonder if you're getting the most out of your refining? Here are a few tips to help you maximize your return from your refining…
Tip 1: Segregate Lots by Type.
If you're sending in multiple lot types, be sure you ask which ones can be mixed and which should be processed separately. Your charges on low grade materials are often based on purity. Therefore, mixing in high value bench sweeps with low value floor sweeps could cost you more in the long run. Crucibles, slag and carpeting are just a few of the low grade materials we process. Mixing these in with higher value materials could skew your assay lower thus costing you more in processing fees.
Tip 2: Cut Down on your Stone Lot Weight.
Processing scrap for stone removal has become more popular throughout the past few years with the increase in diamond sales. At United, we base our charges on the net weight received which means, it best to cut down on the weight. We recommend cutting the excess pieces where no stones are set and sending that in with your regular scrap. With a ring, you may want to cut off the head and send the shank in with your scrap. Same with a nameplate bracelet or necklace. Trimming that excess gold where no stones are set can ultimately help you trim your fees thus maximizing your return!
Tip 3: Avoid Minimum Charges When Possible.
If you're sending in scrap gold, you can mix the various karats together. While some customers like to process their 10K, 14K and 18K separately, this isn't necessary. In doing so, you're creating more (smaller) lots which are subject to a minimum charge. We recommend creating a paper assay and then mixing your gold together to be processed as one lot. You should be able to calculate the value in your paper assay and compare it to our fire assay results. If you tested the gold properly and were careful, the results should be reasonably close.
