  • "When plants are burned, the inorganic constituents remain behind in the ashes, and it is by the lixiviation or leaching of these ashes that potash was first obtained, a process with which the Greeks and Romans were acquainted, although they were unable clearly to distinguish potash from soda, calling them both by the same name (νιτρον, nitrum)."
