  1. 3 things. You can see barren white patches, and areas where the glazed is pooled: which indicates it is over-fired.

    The coarse texture of the clay indicates that the clay is under-fired: immature. The slight off set where the crack is also suggest that the clay was immature.

    The uneven texture where the glaze did shiver off also indicates a bond failure between the clay and glaze: which also means the flux level in the clay is way off.


  2. The concentric crack on the bottom piece is aligned where this piece made contact with the kiln shelf. The exposed area of this piece cooled at a different rate than where it made contact with a shelf. You need to control the cooling to correct it, or put wadding under it to even out the heat.
