Bullion is gold, silver, or other precious metals in the form of bars or ingots. Bullion is

used for trade on a market. The word "bullion" comes from the old French word

"bouillon" which meant "boiling", and was the term used to describe the activity of a

melting house. The value of bullion is determined by the value of its precious metals

content which is defined by its purity and frame. To assess the purity of gold bullion, the

centuries old technique of fire assay is still employed, together with modern

spectroscopic instrumentation, to accurately determine its quality to ensure the owner

receives fair market value for it. It is also weighed extremely accurately.
