Gold

Gold - the legendary metal


What exactly is gold?

Gold is an element, number 79 in the periodic table of the elements, and - who would have guessed that?- a metal.
It has a relatively high density of 19.3g/cm3 and is only with 0.004 ppm involved in the structure of the earth's shell.
The melting temperature is 1063°C.

In the electrochemical galvanic series gold occupies the first place - i.e. it is the noblest of all metals.


What is gold worth?

Gold has always been coveted.
It is the most stable currency in the history of mankind, so to speak the "pillar" at which any other value can be determined.


Gold - the first metal

Yes, I admit it, and with pride: I work in one of the oldest professions in the world!
No, not what you think now!

First pieces of jewellery consisted of natural materials like shells, bones, wood or teeth.
Already in the Paleolithic Age, 90,000 years ago people adorned themselves. Although jewellery is actually classified as a luxury good, it seems to be a basic human need to adorn oneself.

Gold belongs to the first metals which were processed by humans.
Already more than 7000 years ago people adorned themselves with this precious metal.

It occurs in nature solid, i.e. e.g. as nugget or small granules and not only bound in ore. This makes extraction or "finding" easier.
The colour also plays a role here: gold and copper are the only non-grey metals.
The sun-yellow colour of gold has fascinated people since time immemorial - and is one of the reasons why it is easier to find, because if something suddenly sparkles sun-yellow between the grey pebbles, one can imagine that it has attracted the attention of our ancestors.

In nature, gold usually occurs as an electrum, that is a natural alloy gold, silver and, depending on the area, other metals such as copper.

Our ancestors astonishingly fast found out how to work gold and make it into beautiful jewellery and objects.
Especially fascinating for me is the fact, that I can recognize tools and techniques on the pictures of antique or medieval goldsmith's workshops, which we partly still carry out today in exactly the same way.
 

Gold - Facts

Chem.: Au (Aurum) Density: 19.3g/cm3 Melting point: 1063°C

Special features:

  • Gold is the noblest of the precious metals

  • the only yellow metal (gold and copper are the only non-grey metals)

  • excellent formability (over 90%)

  • Most stable currency in human history.

  • Gold can absorb heat radiation to a high degree and is used, for example, as a coating in the helmet visor of astronauts.

  • Other uses besides jewellery: technology, pharmacy + surgery, dentistry, electronics, radiation protection, and many more.

By the way: For the sake of the environment we only use recycled precious metal!
