have you ever?
Have you ever seen sheet of newspaper/magasin fired at 1230 Celsius? well if you are not a ceramist, probably not. So here, have a look ;) Paper includes kaolin, which makes it possible that sometimes, the paper survives the firing, sometimes up til 1280 Celsius!
It shrinks extremely, and it is a shell of ashes, which basically dissolves in the air by the softes air movement. However sometimes, the paper get hide in clay, and is quite protected during the firing, and it is possible to pick it up and move it. It is still a shell, made of ashes so I have to be careful when moving it.
