At my local pottery store I found;

CaCO₃, BaSO₄, ZnO, MgCO₃, MgO, CaF₂, Al(OH)₃, Al₂O₃, SrCO₃, BaCO₃, Sb₂O₃, FeCr₂O₄, Fe₂O₃, CuO, iron powder, Cr₂O₃, TiO₂, Ni₂O₃, NiCO₃, Co(NO₃)₂×6 H₂O, Co₂O₃, MnO₂, CoCO₃ and Li₂CO₃!  

What's up with you guys? The above listed inorganics are very likely to be found in a shop like that, as many of them can be used as pigments, for glazing, etching and other hobby uses. It gives people a hint of what can be found OTC, at least in some parts of the world.

No Joke !!!!!  No misinforming!!!!!!

With a little bit chemical knowledge u can buy my mentioned chemicals in every "drug-store" in germany.
Ok, some reaktions have to be done but.... all these chemicals are available. I swear.
So no misinforming.........

The joke was that i dont understand why the original post was rated as good read... so i thought my could be.......

I was unaware that those inorganics may be had from a pottery store.  So thank you, wolfram, for putting me in the know =)

Thanks wolfram, that was interesting,

Politoxico: In a way it was misinforming in the sense that many of the aforementioned chemicals do not exist, at least in the way they were spelled.
