The early potash industry actually created this element from wood, with the 'pot-ash' name reflecting how this naturally occurring substance was initially manufactured. First, wood (typically hardwood) was burned to ashes. The wood ashes were collected into a pot with water, and then leached to produce lye. At this point, the lye solution ...

A run-of-mill potash ore sample with a high water-insol content from the Carlsbad, N. Mex. Petrographic and X-ray diffraction analysis of the ore indicated that sylvite (KCl) and halite (NaCl) were the major minerals present. The sylvite contained minor amounts of included hematite, which gave this mineral a distinct red color.
