I was thinking about the realization of a pottery oven, and I wondered which material I could to make the inner walls. Most often the inner walls seem to be made of some kind of hard mineral wool. I also had the idea to make them in fire clay, but then I wondered if titanium would hold such temperatures (up to 1200-1300°C).
It seems mechanically OK, but I feared there might be a possible problem of oxidization, if not even a risk of fire. At what temperature might such kind of problems appear with titanium ?
