Two hundred years ago, as media technologies were growing in popularity, new mass production techniques were also being developed. Using the vast networks of the British Empire, huge quantities of material were delivered to factories from all over the world, ready to be turned into all kinds of technology. Mercury is a very useful metal. It is liquid at room temperature, conducts electricity and expands when heated. It used to be widely used in thermometers and is still found in electronics. Unfortunately it is also toxic and can harm people and the environment.
