Zeolite was first discovered by the Swedish mineralogist Kronsted in 1756.
While working in a smelter, Kronsted noticed that the molten ore behaved as if it was boiling, and heating of the zeolite moisture is released with foaming. He named the ore “zeolithe” after the Greek “zein” (to boil) and “lithos” (stone).
In nature, zeolites form when volcanic ash comes in contact with alkaline reaction water, causing rapid crystallization.So far, over 50 species from the group of these minerals have been identified, the most important of which are: clinoptilolite, natrolite, shabazite and heylandite – filipsite. Natural zeolites are hydrated aluminosilicates of alkaline and alkaline earth elements
