Did the Ancients Really Make Gold?



For my first article, I am posting one that was originally posted to another of my blogs but it is a subject that has interested me for a long time. 


Why do we love GOLD?  Since time immemorial, gold was valued as precious in many different cultures, spanning the globe. Its value was recognized even before written documentation of this in the rise of civilization.   Artifacts such as the interesting  stylized‘airplanes” from the Colima Culture in Columbia ( circa 800 BCE) as well as artifacts in the Americas such as gold objects found in the mounds in Florida, Georgia and Ohio point to the fact that gold was prized by many different cultures. So what is it about gold that makes it so valuable, so sought after to the point of people having “gold fever” and could we make it?

The Alchemist, by Paulo Coelho, discusses the theory of being able to somehow change common elements such as lead into more valuable ones such as silver and gold. While alchemy is said to point to how to obtain a more spiritual life, it was the practice of changing or transmuting these elements into gold. This process was kept hidden and  instructions were written in symbolic terms that were understood by a select fraternity of alchemists.

To answer this question as well as the question as to whether or not they could actually make gold, I did some research on the subject of gold and alchemy and the quest for making gold. I am not sure why, maybe like most of us, the idea of having however much gold you wanted was an interesting idea. If you could make it, you wouldn't have to search for it, like some treasure hunters did. Paracelsus,  the father of chemistry, called the art of alchemy, "the  treasure of treasures" for alchemists.

From what I gathered from the source documents on ancient alchemy texts is that one first had to obtain what was called, "the Philosophers stone." But this was just the beginning of a very complicated process that with time, eventually evolved into what we know to be chemistry. Because alchemists had need to keep their processes secret, both from the church fathers as well as the state, they wrote their texts in very complex and obscured language, using symbols and allegory to keep the uninitiated away. 

It was felt from the time of Aristotle that all matter consisted of four elements, namely earth, air, water and fire. The alchemists believed that in the correct proportions and combinations, that the base elements could be rearranged by the use of heat as well as other processes, to transmute them into gold. The main goal of  alchemy was to transmute lead into gold. Lead, it is now known has the atomic number 82 and gold the atomic number 79, which are defined as elements by the number of protons they possess, and changing the element requires changing the atomic number or protons. These protons can't be changed by any chemical means. However, by the use of physics, protons can be added or removed to change one element into another. To change the three protons of lead, an enormous amount of energy is required, so that the cost of transmuting it would greatly outweigh the value of the manufactured gold. It wasn't until the 19th century that their assumption that there were only four elements was found to be false.

With the 20th century and the atomic age, the discovery of ways to break down the elements to their basic structures to form new compounds was not just a medieval superstition any longer. Nuclear reactors also may used for creating elements, although the conditions are less controlled. The Hadron collidor built in 2008 has not only recreated known elements, it has created two new elements on the periodic table, namely ununqadium (114) and ununhexium (116).Today these particle accelerators transmute elements on a regular basis. There is some discussion on websites that feel that the transmutation of gold has been achieved as early as the 1950's. It is now a known fact that the element Lead (Pb) can be transmuted into Gold (Au) by a "simple" nuclear reaction   This process was carried out by tossing one element into a particle accelerator and smashing it into another particle in order to create a collision strong enough to swap a few protons and neutrons, and thus create the new element of interest. In 1951 Glenn Seaborg succeeded in changing a minuscule amount of lead into gold.  

Reportedly in 1972 in the Soviet Union, physicists at a nuclear research plant discovered that they had inadvertently created gold when the lead covering of a reactor transmuted. I would think that any gold created from these processes would not only be extremely costly and time-consuming, it would also be harmful and transient, as would probably decay back into lead quickly. These reports that gold is being created have not been unsubstantiated, so, I guess my quest for making  gold is a bust. I may have to go out and buy a lottery ticket.

Our money system here in the U.S. used to be based on the gold standard. Nowadays the value of money is fiat currency. But gold is still valued but one has to wonder what would happen to its value if the ability to make it synthetically became economical. My guess is that it would not have a significant effect on our economy, as real gold would still hold a higher place value in people’s perceptions. For example we have had the ability to create synthetic gems and diamonds since the early 1970 (plasma diamonds are now being created or “born”) but natural diamonds are still prized. Many people like the idea of synthetic diamonds because they are not associated with those obtained under inhumane means (blood diamonds). 

So why use gold?  Of the 118 elements, there are eight noble metals, "noble" because they stand apart, barely reacting with the other elements: platinum, palladium, rhodium, iridium, osmium and ruthenium, along with gold and silver. These eight are all pretty rare, which is important criterion for currency. But some of them still have problems in that regard. Iron rusts, and it is pretty heavy. Imagine carrying that around in your pockets. With some of these metals, they are so rare, the odds of having them is pretty remote (might have a hard time finding them in your pocket….hope there is no hole!)  Some of them are hard to extract; platinum melts at 1,768 C.

So that leaves us with silver and gold. They are rather scarce but not terribly so and melt at relatively low temperatures so can be easily made into coins, ingots, or jewelry (my favorite).  One problem with silver is that it tarnishes, reacting to Sulfur in the air.

And then we have gold. Gold is considered an inert element. So if you create an object de’ art, a millennium from now it will still be around looking beautiful (unless somebody has melted it down). So that brings us to the only quality that makes gold stand out king among the other metals (noble as they are). It’s golden color. All of the other metals, except of copper, are silver colored or dull metal colored. And copper turns green when it corrodes (not pretty). So perhaps this is the real secret to gold’s allure….its beauty.
