I’m not familiar with jewellery gold, so thank you for the detailed information on that subject. The reason they don’t use ‘pure’ (99.99%) gold as jewellery is that it is too malleable, which metallurgically is the opposite to brittle. Gold is actually the most malleable of all metals.

 

1 gram of pure gold can be rolled into a 1 square metre sheet, that sheet becoming semi-translucent.

 

Reflecting on that outstanding information made me realise why I took redundancy after 15 years in the steel industry to move onto more exciting employment.

That's why in the old cowboy movies they quite often had the scene where the test on the 'gold coin' was biting. A strong bite would leave a  mark
