Oatmeal & Field Mouse Brown Ash Glaze

I did my second cone 6 ash glaze test fire yesterday. I tried the Frasca base glaze with colourant additions as per the Oatmeal and Field Mouse Brown glazes in Roy & Hesselberth. I think they turned out very well. In fact if I was English I would say I'm well chuffed. Not sure exactly what that means though.


From left to right:

• Oatmeal Frasca over Bone
• Field Mouse Brown Frasca over Bone
• Blue Frasca over Oatmeal
• Field Mouse Brown Frasca over Oatmeal
• Oatmeal Frasca over Oatmeal

I'm very happy with the Blue Frasca over Oatmeal. I think this combination is a winner.

It may seem a bit strange to try Oatmeal and Field Mouse Brown. They're quite similar in the colourants. In fact, they're identical save for a very small addition of cobalt carbonate in Field Mouse Brown. The results in these additions to the Frasca Ash Glaze are noticeable but, close enough that I would probably just save the cobalt carbonate and go with Oatmeal. The reason I did both though is because I think both of these glazes are amazing.

There is a caveat though, the Oatmeal under the ash glazes was applied quite thick. I'm going to redo these tests with more appropriate glazing.

Next up, I'm interested to see how these look over a black glaze. I'm also going to try the Spearmint colourants in a new batch and try that out. I suspect it will look fantastic.
