Nightmares from the past - what makes for a really bad day!
Pictured is our elevator kiln with what was 4+ levels of glazed field tiles, round and square caps, and mudbases. The kiln envelope is lowered onto the base for firing, and apparently the temperature probe got bent and pressed up against one of the shelves. This skewed the readings that were being fed to the computer causing the kiln to over-fire by quite a bit....
This photo shows a collapsed tile rack holding square caps and blue field tile that have fallen on top of them.
Here's the back side showing another rack with yellow square and round caps. The rack sits on a lovely misshapen set of large round shelves. They were rated to cone 10, so that's an idea of how hot it got in there. Under that warped mess are 3 more shelf levels that have square caps.
Here's a view of that large 1/2 shelf in an interesting shape. The clay body is a cone 6 porcelain, but glazed with a cone 01 glaze that melted right off the clay onto the shelves.
And this spongy mess.....well, this was a tile setter that was rated to cone 10, but since our porcelain field tile seemed to hold their shape better than this piece of tile furniture, I'm guessing it wouldn't have really passed the cone 10 test firing. However, we're quite sure the interior of this kiln easily made it to a teenager cone temperature.
The photo I was looking for was of my husband rigging up 2 Skutt kilns on their sides to try to fire a very large sample tile for Bill Gates......well, that's another story.
