Gold, 'the noble mineral'
Just been reading my new book, gold, fossicking in Qld, by Barry Neville. I quote some interesting info;
" The colour, hardness ,malleability & melting point of gold alloys vary considerably . Those containing platinum or palladium form the white golds, which are often used in jewellery settings because they are harder & more durable. Gold alloys are also used in dentistry , & for brazing & soldering. Other uses include gilding & gold leaf for decoration of internal & external surfaces of buildings [ roofing, mouldings, sculptures, picture frames or furniture] and for sign writing & book binding.
Gold is used as a pigment in glassmaking, [ ruby coloured glass] and in special glass for climate control of modern buildings. There it reflects external solar radiation to cool in summer, and internal heat inward during winter.
Because of its unique properties gold is used in drugs for certain treatments and in research programmes. it has many applications in in medical devices and since gold is resistant to bacterial colonisation, it is used in transplantation devices and implantation stents as well as electronic components of pacemakers & ventilators.
Who'da thunk, Bob
I’m pretty sure the dinosaurs died out when they stopped gathering food and started having meetings to discuss gathering food
A bookshop is one of the only pieces of evidence we have that people are still thinking
