Dry blowing is a method of gold extraction where dry soil is placed in a tray or container and agitated to separate gold from other material. The lighter material is blown away by air while the heavier gold particles remain in the tray. This technique was commonly used by prospectors during the gold rush.
The weight and purity are not related. A karat is a measure of purity when talking about gold, while a karat for a diamond is dependent on size so if the 10K and the 18K rings are approximately the same size, I would say that the 18K is heavier
relative density is related to the density of water. i.e. a relative density of 19.3 means that it has a density 19.3 times the density of water. The density of water is 1g/ml therefore the density of gold is 19.3g/ml
No, a gold clad coin is not pure gold. It is typically a thinly plated layer of gold over a base metal. The thickness of the gold layer can vary, but the majority of the coin is made up of the base metal.
