A small splint of wood, tipped with some very inflammable composition, which bursts into flame upon friction. The first used were brimstone matches, tipped with sulphur. In 1829 an English chemist discovered friction matches, and the making of matches is now an important industry. The best wood for matches is white or yellow pine. The wood is cut into blocks, and the blocks into square splints. The splints are dipped into melted sulphur, and afterwards into phosphorus, mixed with nitre, fine glue, etc. Safety matches can be kindled only by rubbing upon the side of the box, on which the phosphorous composition is glued.
