Yesterday’s firing was my first gas firing of this glaze, body, and pigment, and first ever primarily porcelain firing.
This piece’s specs:
Porc:Sandstone body 6:4
Taishu:Ash glaze 7:3 @ 40°
Gosu:Oni-ita pigment 6:4 (7:3)?
Orton cone 7.5 light reduction
Pigment blacker than expected, too thick or maybe not enough reduction?
Body is not vitrified completely at this temp, but pure Izumiyama probably would be. Good for teaware and tableware, but for restaurant use should probably be fired higher.
Hey Mike,
Beautiful texture on the trimmed surface. I don’t mind the blackness of the decoration, but you made it.
Got a question about the glaze you’ve got written up
“Taishu:Ash glaze 7:3 @ 40°”
What’s Taishu, and what’s the 40˚ mean? I guess that Taishu means a certain clay, and 40˚ to do with the density? But I’m not sure.
thanks from Austria
Hi! Yes, it is Taishu feldspar, and the specific gravity number on my hygrometer.
