karen, i have some yellow ocher if you would like it.  have had it since early 90s and never used it. it weighs about a pound on my 1950s baby scale.  it is yours for postage if you like.

 

Yes, I would like it. That is generous of you.

Ah intuition somewhere you knew it was ok!  Nice glaze Karen it really picks up the texture.  Now what is cheaper? Crocus or Ochre? 

 

,Thanks Babs.   I'll have to remember to look at the catalog when I go into the studio to look it up.

 

I don't think it is calcined, doesn't say on the label.

Hope the person who was not going to kiln wash her shelves is reading......

Good luck Karen.

Got the chem comp of Yellow ochre?? FeOH

Prob will be paler as from reading, crocus martis unless calcined will gas off a lot in firing. therefore weight for weight it will give less colouring effect.( I think) Croc  FeSO4

Wanted to thank you for the chem comp Babs.

Lucky me. The test on the left is the glaze from the test batch. The test on the right is the new batch with the crocus martis yellow.

 

Just a note that the other colorant is Copper Carb.
