Every pane of glass around you. 🪟 Every window. Every phone screen. Every car windscreen. Every skyscraper.🇬🇧 All made the same way. All using the same process. Invented in a kitchen sink in Lancashire. His name was Sir Alastair Pilkington. He wasn't even related to the glass company. He just happened to share the name and married into the family. In 1952 he was doing the washing up at home. He watched the grease float on the water. Perfectly flat. Undisturbed. And thought: what if molten glass could do that? Before this moment, flat glass had been made the same way for three hundred years. 😰 You melted sand. You poured it into sheets. Then you ground it. And polished it. By hand. For hours. A third of every sheet was wasted in the process. The work was brutal. The results were inconsistent. Nobody questioned it. That was just how glass was made. Pilkington went to his bosses at Pilkington Brothers in St Helens with his idea. They backed him. It took seven years. It cost £7 million. An enormous sum in the 1950s. There were years where nothing worked. The company nearly went bankrupt. His idea: pour molten glass at 1,100°C onto a bath of molten tin. Glass is less dense than tin. It floats. It spreads. Both surfaces fire-polished perfectly flat by the heat. No grinding. No polishing. No waste. 🔥 In January 1959, it worked. The float glass process was licensed to manufacturers across the world. Over 40 companies. Over 30 countries. Today it accounts for over 90% of all flat glass production on Earth. Every window you have ever looked through in your entire life was almost certainly made using this single British process. Sir Alastair Pilkington was knighted in 1970. Elected Fellow of the Royal Society in 1969. Made a life peer in 1995. Baron Pilkington of St Helens. He died the same year. Before he could take his seat in the House of Lords. A British man with an idea who changed every building on Earth. 🇬🇧 Be part of us - proudofus.co.uk Be proud of us. 🙏🇬🇧
