A few trivial & fun facts about GOLD.
This guide is not so much about knowledge, rather it’s about a few little known facts and trivia about gold… something to bring up at a dinner party.
ALL the gold ever mined would fill a cube approx. 20 mtrs x 20 mtrs x 20 mtrs.
One ounce of gold measures about 12mm x 12mm x 12mm or x 1/2'” x 1/2” x 1/2 inch. Tiny for the weight.
It is 19 times heavier than water. Lead is 11 times heavier than water.
A cubic foot of gold weighs about 1/2 ton. Just think about that for a moment. That’s the size of a ruler, cubed.
It is the 58th most abundant element on the Earth out of the 92 natural elements found.
1 ounce (31.1gms) of gold can be drawn into a wire 5 miles, that’s about 8 kilometrers.
You can beat 1 ounce of gold to a sheet of over 160 square feet and that light would shine through that sheet. 1 gram can be flattened into a sheet 1 meter square.
That sheet of gold would be one hundred thousandth of an inch thick.
Historically a carat was a measure of weight based on the weigh of a carob seed which in nature has a very consistent weight.
It has been estimated that 75% of the total historical world production of gold has happened after 1910.
The word ‘gold’ comes from the old English word ‘geolu’ or ‘gelo’ meaning yellow.
Chemically gold is almost chemically inert and is called a Noble Metal because of that fact. Very few chemicals can attack it, so that’s why it keeps it shine even when buried for 1000’s of years. Aqua Regis (Kings water) is an acid that will dissolve it. It is a mixture of concentrated Nitric and Hydrochloric Acids. There are a few Cyanide compounds that will also dissolve it and are used in gold refining. Trust me, you don’t want to go near either.
Because of it colouring effect it is used to colour glass. Those lovely Ruby and Cranberry glass items you see owe their beautiful red to minute amounts of dissolved gold.

The largest gold nugget known to be found was called ‘The Welcome Stranger’. Found in Dunolly, Victoria, Australia, weighed a massive 2280 troy ounces or 70 kilograms.
The largest gold nugget still in existence is ‘The Hand of Faith’ also found near Dunolly. It weighs 875 troy ounces or over 27 kilograms. It is also the largest nugget ever found with a metal detector. Just imagine hearing your detector go of, digging down and finding that baby.
Gold, a truly noble metal with some remarkable properties. A pleasure to hold and behold.
