The alloy
Electrum is a natural alloy of gold and silver, usually with traces of copper and other metals. It is paler than pure gold, and the more silver it holds the whiter it looks. The name comes from the Greek elektron, a word the Greeks also used for amber because of the similar colour.
The first known coins were struck from electrum in Lydia, in what is now western Turkey, around 600 BC. The ancient Egyptians valued it too, and are recorded as capping obelisks with it so that they caught the first light of the sun.
In colloidal form
A colloid is a liquid carrying particles between roughly 1 and 1,000 nanometres across. A nanometre is a billionth of a metre. Particles that small do not sink, yet they are large enough to scatter light, which is why a beam shone through a colloid shows up as a visible line.
