"Billiard equipment improved rapidly in England after 1800, largely because of the Industrial Revolution. Chalk was used to increase friction between the ball and the cue stick even before cues had tips. The leather cue tip, with which a player can apply side-spin to the ball, was perfected by 1823. Visitors from England showed Americans how use spin, which explains why it is called "English" in the United States but nowhere else. (The British themselves refer to it as "side".) The two-piece cue arrived in 1829. Slate became popular as a material for table beds around 1835. Goodyear discovered vulcanization of rubber in 1839 and by 1845 it was used to make billiard cushions. A two-to-one ratio of length to width became standard in the 18th century. Before then, there were no fixed table dimensions. By 1850, the billiard table had essentially evolved into its current form."
