Potassium salts in the form of saltpetre (potassium nitrate, KNO 3), alum (potassium aluminium sulfate, KAl(SO 4) 2), and potash (potassium carbonate, K 2 CO 3) have been known for centuries.They were used in gunpowder, dyeing, and soap making. They were scraped from the walls of latrines, manufactured from clay and sulfuric acid, and collected as wood ash respectively.

Scandium is very much a late starter compared to many of the other elements, due to its relatively low occurrence and the difficulty in obtaining it from its ores. For example, it wasn't until the 1960s when the first pound, or 450 grams, of high purity scandium was obtained. Compounds of scandium find use in organic chemistry.
