White phosphorus was poisonous to match makers, causing Phossy jaw. Albright and Wilson exhibited amorphous phosphorus at the Great Exhibition of 1851, at The Crystal Palace. A sample was taken away for testing by the two Swedish brothers Lundström, to make an experimental match composition. In 1855, just before the Paris Exhibition, John Edvard Lundstrom found that the matches were still usable. He placed a large order for amorphous phosphorus with Albright and Wilson and this led to the foundation of the Swedish Safety Match Industry.
