This came out of a 12 hour wood firing.

What sort of temperature are you firing to? The kiln I occasionally firing is usually going to Orton cone 13. It can produce great results, although I think it to be an excessive use of heat work and a waste of fuel to try and achieve the beauty that is evident at the lower temps traditionally used in Japan.

That yunomi probably fired to Orton cone 10. Yes, that is one of the bases. I have been doing line blends of korean kaolin and neph sye from 70/30 to 30/70 and they all work. Korean kaolin has more alumina than our Kaolins back home.
I flatten Orton 13 in 12 hours in my woodkiln. I use 400kgs of scrap wood. I think the temp at the fireface is over cone 14.

But you know, here in Japan they fire their shinos for 10 days to two weeks. It take tremendous amounts of fuel to fire for that long. A quicker firing to cone 13 saves fuel.
