The chemistry of line

The chemical and physical properties of line, especially when reasonably pure, make it highly sought after for hundreds of everyday uses. With salt and coal, it formed the main feedstock for the chemical industry until about 1914. It is still important today as shown by the wide range of uses in Tables 1 - 4 (Appendix).
