Houhins, shibos...

The recent kiln load was mostly shibos and houhins fired to 1250 degrees Celcius. The clay was mostly a mix of Witgert and a local high-iron clay. The local clay has so much iron in it that the gasses get trapped and bloating occurs even when fired slowly (12 hours to 1250 degrees), so I mix in a bit of leathercoloured German clay to amend that problem. The blend results in a more "manila"-ish hue, a soft satin like surface that would be great if it just had a little more variation (flamemarks is what I really crave, but not likely to get that in an electric kiln!).
