Dear All,
Apart from all the previous comms. on the matter, mercury was also used for
'silvering' Top Hats: hence the genuine reason & explanation for the Mad
Hatter. However, we all forget the use Dental Amalgam; electron microscope
pics. make interesting viewing! - in fact you don't need the latter, a x60
microscope can be sufficient depending on how old the filling is. Gold is of
course used, but how many of us have amalgam fillings? Luckily new technology
is replacing amalgam with ceramics, etc., so, hopefully, amalgam will be a
thing of the past over the next few years. Regards, Bernard.
