Re: Mercury, and Titanium
" I can remember a small brown ceramic bottle full of the stuff, it was extremely heavy and fun to play with.
In the 1960s when we were 12/13 years old our Physics teacher taught us about density and Archimedes Principle etc. He poured mercury into a beaker on the bench for us to feel the weight of the liquid metal - and we had fun chasing tiny quicksilver beads across the bench.
The lab technician made audio wave demonstration glass tubes by taking apart dead fluorescent tubes and cleaning off the phosphor coating.
In the 1930s my mother was a painter of ceramic flower bowls. She related that one day one of her workmates had a discoloured gold wedding ring after she had washed her hands. Someone had used the sink for washing off some mercury after renovating a mirror.
