This firing of the kiln went too long, resulting in Orton cone 11 flat.\u00a0 Ideally, it would be cone 11 touching, then sagging a bit.<\/p>\n

Upon unloading the kiln this morning, one thing was immediately apparent: the right side was far more reduced than the left. Yellower glazes and more slumping. Even on the left side there was some slumping, because of the excessive temp., and because of the clay which contained some low temp high iron clay to help seal the ware against leakage.<\/p>\n

Right side sagging badly, white glaze turned yellow.<\/figcaption><\/figure>\n

Chosen Karatsu came out pretty good, but the white was on too heavy, running down the pots too much.\u00a0 It still came out looking ok because of the clay.<\/p>\n

Most of the teabowls warped or sagged, so I only get to keep 2 or 3 of the 15. This is why teabowls are expensive, kids…\"IMG_3399\"<\/a> \"IMG_3398\"<\/a><\/p>\n

All in all, not a bad firing, but need to adjust clay bodies, and pay closer attention to cones. Also, figure out the over reduction on the right side. It might be that one burner that sounds a bit off.<\/p>\n
