The colour ‘mauve’

Back in 1856, there was no cheap way to manufacture purple dye. It was by accident that chemist William Perkin discovered a new colour (mauve) when he was cleaning up after a messy experiment. Queen Victoria brought mauve into popularity when she wore a dress of that colour.

Non-stick pans, inhalers, white paint, antifreeze, heat packs and digital cameras are all common items which have come into being thanks to the efforts and ‘accidents’ of chemists.

Petrol engine

Engines need power to operate. In 1870, Austrian scientist Siegfried Marcus got the idea to use petrol as a fuel to make an engine run – an early version of a motor vehicle.

Matches

A match tip is a mixture of substances that catch fire when rubbed against a rough surface. Englishman John Walker invented the first safety matches in 1827.

Batteries

Inside a battery are two different metals in a liquid which make an electric charge flow by reacting with each other. Italian Alessandro Volta performed some of the earliest experiments with batteries in 1791.
