18k white gold is a newer alloy and is often confused for silver. Our white gold powders are formulated with palladium to provide a more robust alternative to silver. It's higher melting point can mean that this powder will create more durable pieces with a high-quality finish. It can be used as a cost-effective replacement for platinum.

Royal is by far the highest quality equipment for the weekend gold miner. This was the first idem I have purchased from Royal. Very happy with the quality, packing, instructions, and the video included. I proses my fine gold inside, thru the winter, so I did purchase a 110 volt pump to keep the water flow more consistent. Thank you Royal.

Silver was mined and used in trading several thousands of years BC and was first minted into silver coins in the Mediterranean region many hundreds of years BC. Until the 20th century, many countries used a silver or gold standard, backing up the value of currency with the presence of gold or silver .
Silver Migration - Silver has strong tendencies to migrate, since silver oxide is water soluble. The migration of silver on electronic assemblies expresses itself in the formation of conductive paths by wandering metal ions and under the influence of humidity between traces of different potentials. Preferred direction is towards the electric field.
A study has been made of the effects of protective colloids in making silver powder by chemical reduction. Gelatin and (especially) casein have been found to give good results; the method of preparing the colloid has a marked effect on the properties of the product. It is essential to use these colloids in order to obtain acuve, fine-grained, and homogeneous powders of light color.

21.08.2017· For gold, the world produced 91% of all gold since 1900, and 81% of all global silver production. According to the best sources (shown on the bottom of the chart), there have been approximately 173,000 metric tons (5.5 billion oz) of gold produced since 1493 and 48.5 billion oz of silver.
The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.
