Hi,
I was wondering if you could help me understand why the wood ashes created that opaque patina in the centre of this bowl and if you think a refire could help.
I mixed unwashed dry ashes to a neutral glaze I regularly use and thickly brushed the mixture on the thinly glazed bowl you can see in the picture, fired to 1260C
on my previous tests I only had shiny crackled amber glass where the ashes where most concentrated.
I know that with unwashed ashes surprises are to be expected and I also welcome them, but I would be curious to understand the possible causes
thank you
Valeria
