Gold is the most recognisable material on our planet. Throughout the history, gold was a sign of wealth, power, and position in a society. Just by going through history books, you can see that almost every civilization, regardless of their geographical location, used gold as their primary currency.
However, that was not the only use of gold. People used it in jewellery, religious ornaments, paintings, furniture, decorations, etc. And why wouldn’t they? The beauty and the shine of gold are still unparalleled. Now, gold gets a lot of flak because most people consider it useless outside the jewellery industry.
However, that couldn’t be further from the truth. Gold is a great electricity conductor, it doesn’t tarnish, it alloys well with other metals, it’s very easy to shape, and it has many other interesting characteristics. You can probably already assume what other uses gold has just by looking at these properties, but we will try to paint a bigger picture so that all of the sceptics realise that gold is more than just bling.
Gold in electronics
One of the most important properties of gold is its ability to effectively conduct electricity. Small devices like smartphones, laptops, computers, etc. require small electrical charges to operate. However, these charges are easily interrupted by corrosion or tarnish.
If you take into consideration that gold doesn’t tarnish and it conducts electricity, then you will realise why almost every connector, connection strip, soldered joint, etc. has some gold in it. Now, you might be thinking “Why is gold used just in smartphones, why not use it on a larger scale?” Well, the answer to that question lies in gold’s rarity.
You see, gold is a highly valuable material, and it costs a lot to mine even a small lump of it. That is why moulding large chunks of gold for a big conductor would be expensive and impractical. While using gold in electronics is doable on a smaller scale, on a larger scale, it is almost impossible.
Gold in finance
Gold’s main use is still heavily rooted in finances. Gold has been a natural currency for a couple of millennia. Even though its monetary function has died out, most countries still have their reserves in gold.
That just speaks to how valuable and precious this material is. Having your savings in gold is probably the smartest thing you can do. Gold’s value is constantly rising, and currently, it’s the most stable “currency” available. Having your money invested in gold bullion is the safest option. Golden coins, ingots, and bars are simply more secure than banks or stock markets.
Gold in dentistry
As funny as it sounds, replacing your bad tooth with a golden one is the best possible thing you can do. Now, stay with me, please. I will explain myself. Gold is a non-allergenic material, it’s easy to mould, and most importantly, it is chemically inert.
For example, if you put an iron tooth in, a bunch of bad things will happen. First, you will constantly have metal taste in your mouth. Second, your tooth will corrode within days. Lastly, you will probably end up with an infection. Even though gold is a great replacement for your teeth, we are seeing gold teeth less and less. That’s because modern dentistry has found equally effective substitutions.
Gold in space
Lastly, gold has a plethora of use in the space industry. One of the biggest virtues of gold is its reliability. Gold is good at certain things, and above all, it’s consistent. In an industry like space where a tiny mistake can spell disaster, reliability is valued the most. That is why gold is used as a lubricant for mechanical parts, protection from infrared radiation, and of course, as a conductor for electricity.
That’s about it for this article. Gold has many other uses in today’s world, but these four are by far the most common ones outside of the jewellery industry. I hope that you have learned something new today and that, from now on, you will appreciate this precious material even more.
