Venicemud Posted September 7, 2013 Report Share Posted September 7, 2013 Is there a difference between yellow ochre and yellow iron oxide? I want to make up a test batch of Hannah's Fake Ash glaze but it calls for yellow ochre which I don't have in my pantry and which Laguna does not have in its online catalogue. They do have yellow iron oxide listed however. Thanks, Joan Klotz (Venicemud) Link to comment Share on other sites More sharing options...
Wyndham Posted September 7, 2013 Report Share Posted September 7, 2013 Googled yellow ocher and wiki said it's the same. Wyndham Link to comment Share on other sites More sharing options...
Bob Coyle Posted September 7, 2013 Report Share Posted September 7, 2013 Yellow ocher is a naturally occurring iron oxide/hydroxide. As such there are variations as with any mined mineral. It is also made synthetically. I would guess that the Laguna yellow iron oxide is synthetic, but it may be close enough to meet your needs. The only way to know is to try it.

Venicemud Posted September 7, 2013 Author Report Share Posted September 7, 2013 Thanks guys, I'll do that. A friend has offered me some yellow iron oxide. I will try to find a source for "yellow ochre" so that I can compare results. Link to comment Share on other sites More sharing options...
Denice Posted September 7, 2013 Report Share Posted September 7, 2013 I just bought some yellow ochre from my local ceramic supplier Evans in Wichita Kansas. I imagine you'll be able to find it someplace closer. Denice Link to comment Share on other sites More sharing options...
dee kat Posted June 14, 2015 Report Share Posted June 14, 2015 Yellow Iron Oxide and Yellow Ochre are not the same. One is an Iron Oxide and the other is a clay. Go to digitalfire.com for checking materials and not wiki. Link to comment Share on other sites More sharing options...

Callie Beller Diesel Posted June 16, 2015 Report Share Posted June 16, 2015 My favourite celadon is quite sensitive to changes in formulation, and uses ochre for a colourant. Last batch I mixed, I was about 50g short, so I used some yellow iron I had instead of running to the a$$ end of the other side of town to get more. It did make a difference in colour. The new batch is a bit more of a yellow green, rather than a Koryo blue green. Still good though. Link to comment Share on other sites More sharing options...
Joseph Fireborn Posted June 16, 2015 Report Share Posted June 16, 2015 US Pigments sells it. I ordered my shipment and got it 1.5 days later. Prices are good too. http://www.uspigment.com/chemicals.shtml Link to comment Share on other sites More sharing options...
