Red Phosphorus: Schrötter's Heat Conversion
Red phosphorus is ordinary phosphorus changed by long, steady heat with no air present. Schrötter described it in 1848: it does not catch fire by itself and is far less poisonous, which made the safety match possible. Muspratt (1860) gives Miller's way of making it in a sealed flask on an oil bath.
