Try unwashed hardwoodash 50% +
and a nice fluid feldspar
plus a white clay like xx or EPK
and a little flint
and screen after blunging
remember that the ash must be
fluffy and not crispy
fireplace ashes or BBQ will do
try it on porcelain
kick me if I'm wrong

Does anyone know if you can mix wood ashes into commercial glazes? I do low
fire work in an electric kiln using earthenware.

I mixed some wood ash into my ^04 clear glaze.It seemed to make it more
fluid and warmed it up a bit. I dont have a steady,consistent source of
ash so I did not follow up on the experiment. I was really just curious
to see if it would have any effect at all at so low a temperature. I'm
surprized it did. Eutectic effect?(Eutectic =combination of two or more
fluxes that produce a melting point below the individual materials)
I would suggest doing a controlled test with your glazes and your ash.
Ash varies quite a lot depending on the wood used, thats why it's good to
have a large supply on hand.
