Although not clearly visible in this photo, the unglazed body surface on both of these MNP (Plainsman 3D + 10% feldspar) pieces has a sheen - because they are super-vitreous. And broken surfaces appear like glass (as can be seen in the broken chips on the right). Because the foot-ring of the piece on the right is too angular it is plucking all the way around. This is not happening on the piece on the left for two reasons: The angle was rounded and it was fired on silica sand. Because it is so fine-grained (wet screen to 325 mesh) and contaminant-free the body tolerates firing well past the point of vitrification - not only resisting bloating and warping but giving something else: Incredible fired strength.

Plucking
A firing issue in ceramics where the foot rings of vitreous ware stick to the kiln shelf. Removing them leaves sharp fragments glued to the shelf. |
