Being denser than the lithophiles, hence sinking lower into the crust at the time of its solidification, the chalcophiles tend to be less abundant than the lithophiles. [103] In contrast, gold is a siderophile, or iron-loving element. It does not readily form compounds with either oxygen or sulfur. [104]
However, iron artefacts of great age are much rarer than objects made of gold or silver due to the ease with which iron corrodes. [86] The technology developed slowly, and even after the discovery of smelting it took many centuries for iron to replace bronze as the metal of choice for tools and weapons.
Ancient Greek mythic-cultural cosmology depicted a decline from a golden age to a silver age followed by an Iron Age. In some variants there is a Bronze Age, an interim between the Iron Age and Silver Age.

In astronomy, metallicity is the abundance of elements present in an object that are heavier than hydrogen and helium. Most of the normal currently detectable (i.e. non-dark) matter in the universe is either hydrogen or helium, and astronomers use the word "metals" as convenient shorthand for "all elements except hydrogen and helium".
The Goldschmidt classification, [1] [2] developed by Victor Goldschmidt (1888–1947), is a geochemical classification which groups the chemical elements within the Earth according to their preferred host phases into lithophile (rock-loving), siderophile (iron-loving), chalcophile (sulfide ore-loving or chalcogen-loving), and atmophile (gas-loving) or volatile (the element, or a compound in ...
Proverbs 27 is the 27th chapter of the Book of Proverbs in the Hebrew Bible or the Old Testament of the Christian Bible. [1] [2] The book is a compilation of several wisdom literature collections, with the heading in 1:1 may be intended to regard Solomon as the traditional author of the whole book, but the dates of the individual collections are difficult to determine, and the book probably ...
The main concordance lists each word that appears in the KJV Bible in alphabetical order with each verse in which it appears listed in order of its appearance in the Bible, with a snippet of the surrounding text (including the word in italics). Appearing to the right of the scripture reference is the Strong's number.
