Thanks

[Jeff Guin]

Thanks for the warm welcome to the group and the answers about my hard
firebrick. I'll be buy ing them as I can afford them. But I have
another question regarding wood firing that I'm sure several of you
can answer. First of all, is there a temperature inside the kiln that
must be obtained for the wood ash to interact with the pottery? I
built a small wood fired updraft brick raku kiln that turned out some
very interesting results. Firing the same glazes in my gas fiber lined
kiln turned out much different results. Basically, what is anybodys
thoughts on wood fired raku verses the American style of Raku firing?
Thanks Bunches.

Jeff,

Could you share images of your results?  My experience has been that the ash melts in the cone 10 temperature range.  I would imagine one could mix fluxes with ash to lower its melting temp--oh, wait, that's a glaze?

Ya Jeff, "glazes" were discovered when the ancient kilns got so hot they melted the ash and people then learned to flux it with other minerals to lower the maturation temperature.

As far as American fired raku and wood fire raku I haven't done any in so long I forget the results but I probably stubbornly preferred the slowness of the wood.
