I have found a reliable supplier for at least some inorganic materials from a U.S. supplier I have not seen mentioned here. I have been getting
Yttrium oxide from US Pigment Corporation (https://uspigment.com) that has been of good qualiuty for pigment making. They carry a variety of inorganic materials useful in ceramics (metal
oxides and carbonates; some nitrates chorides, sulfates, sulfides, dichromates), as well as rare earth oxides. There are some uncommon and toxic
materials, including a thing or two I have not seen elsewhere (one of them useful for making mid-19th century green pigments among them) so please be
careful and use them responsibly.
I should probably also mention that I have also had good experience with materials from Seattle Pottery Supply, though what they carry is far more
limited and less exotic. But it is local for me. See https://seattlepotterysupply.com/pages/raw-materials
