0 Rare and beautiful
The noblest of metals
Gold is precious, there’s no doubt about it – but why? It’s true that it has certain properties that make it useful in electronics, aeronautics and medicine. For thousands of years, however, gold had little practical value. It was prized for its shine, the fact that it never rusts, and for its rarity. It is also soft and easy to shape. These were reasons enough for humans to rob and murder each other and destroy the environment in their drive to own more of the precious metal.The items on display belong to the Goldkammer Collection.

How gold came to earth
The earth’s crust is full of gold, but it’s normally found only in very low concentrations.  Alchemists have tried for centuries to make gold. This was always doomed to failure: gold is a chemical element and it is impossible to produce it artificially.
Gold can only be formed by either nuclear fusion or nuclear fission. Such a process normally occurs during major cosmic events – a massive star exploding sometimes causes new neutron stars to be born. If two of these stars collide, new chemical elements such as gold can form.
The Earth’s gold was formed in a similar cosmic event. More gold was probably also brought to our planet by meteorite impacts billions of years ago.
2 Unknown: Workshop of an alchemist, Engraving, 1735.
The goal of an alchemist was always to make gold. Alchemy was the precursor to the modern science of chemistry, which was first developed around 1800. Nowadays, we know that it is impossible to produce gold chemically.

After creating “red porcelain”, the alchemist J. F. Böttger went on to discover white porcelain in 1710. It was certainly not gold – but his discovery made Böttger’s home town of Meissen very wealthy, and it became known as the capital of porcelain.

Where to find gold
When the Alps were formed, it caused the earth’s crust to crack. Rainwater soaked into the crust, where it grew hot and then evaporated. The resulting vapour was full of elements carried from the earth’s crust. The gold particles crystallized and formed gold-bearing quartz veins to a depth of ten kilometres.
Millions of years ago, rivers carried sand, scree and small amounts of gold down from the Alps to the Plateau, forming huge alluvial fans in the Nagelfluh conglomerate. The Napf is one of these alluvial fans, carried there by the primeval river Aare.
Nowadays, flakes of gold in the Nagelfluh conglomerate are carried along by streams, accumulating in the stream beds. These deposits are called “alluvial gold”.
8 The primeval Aare River once flowed from the Valais Alps down to the Napf region.
9 Gold ore from a quartz vein near Brusson in the Aosta Valley, Italy. The oldest gold deposits in the Alps are in this region.
10 A piece of the Nagelfluh conglomerate from the Napf region.
The Nagelfluh is made up of gravel and sediment, which originally came from primeval riverbeds. The sediment from these rivers sometimes contains gold.
11 Gravel from the Nagelfluh conglomerate in the Napf region.
The wide variety of pebbles in this conglomerate allows us to understand how this rock was formed. Rivers carry sediment from several regions. This sediment then agglomerates, forming new rock.

1 Grosse Fontanne, Napf region, Canton of Lucerne
2 Grosse Fontanne, the largest gold flake ever found in Grosse Fontanne, found by Gabrielle Lièvre in 2008

13 Gold ore and alluvial gold
Two ways to extract gold
“Gold ore” can be distinguished from “alluvial gold” by the method of extraction.
Gold ore is mined and then crushed. The gold is then chemically separated from the subsequent mineral sand. Mercury is often used in smaller mines. In industrial mines, cyanide is used. Both products are highly toxic and accidents have catastrophic consequences for people and the environment.
Alluvial gold that has settled in riverbeds is separated from the river silt using gold pans or sluices. Usually only a few millimetres of gold flake are the result – with a lot of luck perhaps a nugget.
14 Californian metal gold pan.
Gold panning takes advantage of the fact that gold is heavier than any of the other elements present in sand. Using a circular motion, any unwanted elements are washed out while any gold flakes stay in the pan.

Industrial gold mining in Switzerland
There are huge reserves of gold in Switzerland’s bank vaults – and very little in the ground. It is likely that even the Helvetians were already prospecting for gold. In the Middle Ages as well as in modern times, gold hunters tried their luck in the regions around the Napf, below Solothurn and near Geneva. For most of them, gold panning was merely a side job.
A few gold mines also existed in Switzerland: in Gondo, at the foot of the Simplon, from 1660 to 1897. In Sessa and Astano in Malcantone and in the Calanda massif there were gold mines in the 19th century, some of which remained open until the 20th century. The gold mine at Lake Salanfe in the Lower Valais produced gold from 1904 to 1924.
More recently, there have been a few unsuccessful attempts to mine gold commercially in the Surselva in the Anterior Rhine.

25 More of a hangover than a high.
40 grams of gold per tonne of rock. According to geologists, it was possible to find this fabulous amount in Gondo at the foot of the Simplon! People had been mining gold there for a long time, but it was clearly time to really get down to business:
“Small investors shouldn’t look to California or the Transvaal, where they often get dividends of 50 percent, because now they’ll be able to get the same in Gondo – and much more besides! “promised the Société des Mines d’or d’Helvétie in 1892.
Investors from all over Europe were delighted. The small mountain village welcomed the latest fashions from Paris, and played host to lavish parties celebrating the future wealth of the region. But the results were dismal… In 1897, the Société went bankrupt.

30 Not always so noble.
The finest gold is not always the cleanest
Gold bars produced by mining companies always contain a percentage of other metals. Its purity – or as it is known in the business “its fineness” – is achieved by refining it. Although gold refineries are frequently located in gold-mining countries, about half of all the world’s gold is refined in Switzerland.
The reasons for this date back to the 1970s, when South Africa was the world’s largest gold producer. Most states boycotted the country over its racist apartheid regime – but not Switzerland, which was happy to accept South African gold.
Even today the world gold trade is not “clean”. Gold is regularly used to finance civil wars. Nowadays, it’s possible to buy fair trade gold, but it remains a niche market.

Jean Ziegler’s 2002 book provides an easy-to-understand explanation of what happened.
36 Making the most of yourself
Raw material for jewellery and silver
Gold’s beauty has always been and remains its most important feature. Most of the yellow metal is shaped into jewellery or used for decoration.
Gold jewellery has existed for thousands of years. In ancient Egypt, the noble metal was used as jewellery, primarily by women. Gold leaf was first produced in India. Using leaf, even relatively large objects could be gilded without needing too much gold. Gold coins of uniform weight and value were first minted under King Croesus of Lydia, in the 11th century B.C.E.

38 Capricious
What’s this? A cracked and damaged brooch? In the 1960s, a young Kurt Neukomm (born 1938) began to produce jewellery that many considered provocative. Yet by the mid-20th century, modernity had finally made its mark on the goldsmith’s trade.
Specialists soon showed an interest not only in Neukomm’s jewellery, but also in the images he used to incorporate gold elements into his work. To this day, many museums display Neukomm’s works.

45 Gold scales
Modern money is based on trust: a five-franc coin or a ten-franc note is worth what it says because we trust the central bank that issued it.
If gold is used as a form of payment, it is different – coins are worth the value of the metal they are made of. In other words, a currency is nothing more than a defined weight of precious metal.
But gold coins have always aroused a degree of suspicion. They are liable to be forged, and who knows if someone hasn’t clipped a little off? This is why merchants and bankers always weighed their coins using special gold scales.
The counterweights were not marked with weights but with the value of the currency to which they corresponded: “guilder”, “ducat”, ” louis d’or” and so on.

49 Radiance and squalor
Gold through the ages
Though gold has little practical value, almost all cultures throughout history have attached great symbolic value to it.
Gold’s lustre is suggestive of the sun. It’s rarity makes it a symbol of wealth. As it cannot rust, it is noble and enduring; symbolic of immortality. This is why gold was often used to make burial goods and religious objects as well as symbols of secular power, like crowns.
The desire for gold has often caused insatiable greed. European invaders cheated and murdered for gold, particularly in America.
50 Unrestrained greed
People call may them “explorers” but conquistadors such as Fernando Cortez or Francisco Pizarro were essentially brigands sanctioned by the King of Spain. Heavily in debt in Europe, they were neither honourable nor restrained in their pursuit of gold and silver.
Atahualpa, the last ruler of the Peruvian Incan Empire, had the misfortune to meet Pizarro. The Spaniard threatened to kill the Incan king, and the latter was forced to promise him gold and silver. Atahualpa pledged to fill an entire room with the two precious metals.
The king kept his promise – it is reported that gathering all the imperial gold together took the Incans three months. Pizarro took the gold but reneged on their agreement. In July 1533, the Spaniards strangled Atahualpa. However, even at his execution he was blackmailed once again – he only avoided being burnt at the stake by accepting being baptised.

60 From gold rush to genocide
The discovery of gold in California triggered the gold rush in 1848. Tens of thousands of people flocked to the west coast of North America, but not many found success.
For the Amerindians, however, it was catastrophic: the gold rush became the catalyst for genocide. Killing any natives that interfered with the search for gold was not only legal, it was rewarded. The state of California paid a bounty for each dead Native American : $5 for a head and 50 cents for a scalp. Within a few years, many Native American tribes were completely wiped out.

63 Gold is everywhere
The precious metal in everyday life
Real gold is usually only used in small quantities. Jewellery notwithstanding, dental crowns and electronic devices also contain gold. The metal is also used in medicine and as an award in athletics competitions – or at any rate something gilded that looks like gold is awarded.
Even though real gold is expensive, it costs nothing to call something “gold” and to use gold as a colour. This is especially true in advertising and in product names as well as, of course, in legends and fairy tales, where the precious metal is everywhere.
