Alloy is a language for describing structures and a tool for exploring them. Most sites mention the values depend on the percentage of gold and silver in the alloy, but provide no actual figures. This suggests that one reason for the invention of coinage in that area was to increase the profits from seigniorage by issuing currency with a lower gold content than the commonly circulating metal. Electrum is a temporal extension to Alloy. The gold content of naturally occurring electrum in modern Western Anatolia ranges from 70% to 90%, in contrast to the 45–55% of gold in electrum used in ancient Lydian coinage of the same geographical area. Its colour ranges from pale to bright yellow, depending on the proportions of gold and silver. Electrum is a naturally occurring alloy of gold and silver, with trace amounts of copper and other metals. The ancient Greeks called it ‘gold’ or ‘white gold’, as opposed to ‘refined gold’. It has also been produced artificially, and is often known as green gold. electrum ( countable and uncountable, plural electrums ) ( obsolete) Amber. This naturally occurring silver and gold alloy enjoyed great popularity in Ancient Egypt. Alloys used in jewelry making range from 9-karat gold, approximately 37 pure gold. So, a 50/50 alloy, half pure gold and half other metal or metals, is 12-karat gold. Contamination is a major issue and every possible adherence to quality and safety must be followed in the alloying and casting of these metals.Įlectrum is a naturally occurring alloy of gold and silver, with trace amounts of copper and other metals. This Type II vinyl wallcovering offers subtle texture in a luxe palette of matte colorways, with metallic accents ranging from cool silver to deep bronze. Pure gold, which contains no other metals, is termed 24-karat gold. I was always surprised, when doing my own casting years ago, to find that a small amount of lead or some other impurity would drastically change the metal.
Shows you just how a small amount of an element can drastically change a base element. Electrum is an alloy made from a mixture of gold and silver, and its properties will depend on the specific proportions of gold and silver used in the alloy.
