My main goal is to try to help you to understand the way the new features are really working.
Kurt Lang which was able to describe the behavior of mac OS regarding fonts (not an easy task) clearly misunderstand these features.
It's only when you will understand them that you will be really able to see their interest.
I apologize but I don't see the link between the computer ruling the oven and the AutoSave feature.
For the rebuilt oven, I'm not surprised.
In an old one, the bricks are impregnated with glaze components (vapors emitted when the glaze is at high temperature). When the kiln reach these high temperature, part of these components leave the bricks and change slightly the kiln atmosphere giving specific results.
When the bricks are new, we don't get this interesting feature (which may become annoying in some cases : if we need to fire perfectly white objects)-. The potter will have to change slightly the glaze formula as long as the bricks will be "clean".
