Mark Miodownik describes the work of the chemist Leo Baekeland, who invented the plastic Bakelite. Baekeland discovered that carefully controlling the speed of the reaction between phenol and formaldehyde produced a mouldable resin. Mark describes the structure of Bakelite and how the links between molecules mean that it will not melt at higher temperatures (like celluloid did before it).
