Kees...

Would you give more information about ceolite? In my searching, I suspect it is the same as zeolite, which is available from pet supply stores for use in aquariums or cat litter.

Zeolite - Wikipedia, the free encyclopedia Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents... Some of the more common mineral zeolites are analcime, chabazite, clinoptilolite, heulandite, natrolite, phillipsite, and stilbite. An example mineral formula is: Na2Al2Si3O10-2H2O, the formula for natrolite.

Am I close? And, what is Pate Hamon... can't find that either.
