Hi (Alll&you)
Can wood ash be calcined?

Hi Ababi
Lets face it, wood ash is calcined wood!
However, if it contains a lot of charcoal, it probably hasn't been
fully burnt, and in this case it can be put in a bowl or sagger etc.
and refired in the bisque kiln. This will burn out the residual
charcoal. the result should be a lot less volume of white fluffy ash.

Thank you all that answered me.
I know you have asked yourself: What happened to the glaze addict?
Calcining ash?
Baking the beckon?
Tearing the tears?
He should know it already!
Please enter to the clayart page in my site and see the ash glaze fired
to crystal.
