Assaying and melting
The process of gold assaying at Gold Bank London ensures that the gold we test meets the correct purity standards and content. Gold coins and gold bar purity always remains essential in the creation of trustworthy gold bullion products and establishing reputable brand or gold bullion hallmarks by both private gold mints and government gold mints respectively.
Gold Bank London undergoes the best method of assaying. We provide accurate assays for both gold and silver. Depending on the type of metal or item being checked for purity. A fire assay then takes place where gold and silver are both checked with corresponding amounts of silver and gold. After this, Gold Bank London takes a sample, either by drilling into the metal for shavings or taking a sample while it is in a molten state before formation into a bar or coin. After this, a sample of the gold is tested to determine how many karats the gold is.
We also offer XRF gold assaying services for instant analysis of your materials. A cutting edge state-of-the-art technology allows results within seconds. This can also be done for customers for free, if you want to valuate your gold or just check in to see how many karats your own gold truly is.
