Round2potter Posted March 8, 2013 Report Share Posted March 8, 2013 I was poking through the studio glaze material supply room looking for some nickel oxide and i stumbled upon a bin of Antimony oxide atop a bin of "tin vanadium"; all of this infront of the Molybendum and Iron Chromate I am not gonna use the Iron Chromate, no need. What is Tin Vanadium? all i can tell from googling is that it is purified using zinc for some fancy reason and then it is almost pure, with just a little zinc left over; but would it be pentoxide or something else? Is it soluble in water like iron chromate? The antimony i know is terribly toxic, as well as the iron chromate, as well as the vanadium to a lesser extent but does anybody know about Molybendum? Or why i cant find any ceramic supplier that carries it? Even the one i found that has erbium, vanadium, antimony and neodynium doesnt have it.

bciskepottery Posted March 8, 2013 Report Share Posted March 8, 2013 U.S. Pigment carries several of your list . . . including molybendum http://www.uspigment.com/chemicals.shtml Link to comment Share on other sites More sharing options...
bciskepottery Posted March 8, 2013 Report Share Posted March 8, 2013 Per Fraser and Fraser (The Potters Dictionary of Materials and Techniques) -- Mollybendum oxide is a refractory oxide used in preparing yellow stains. It acts as a stabilizer in glazes. Poisonous. Antimony – used to modify lead oxide to make yellow. Poisonous. Does not dissolve. Used mostly at low fire – volatizes at stoneware temperatures. Found nothing in Fraser regarding Tin Vanadium – Fraser did say that tin and vanadium are used to make yellow color in stains or glazes. Link to comment Share on other sites More sharing options...
