Normally, mugs are ceramic and thus the parts that had to touch the shelf in the kiln are unglazed. Maybe we just need to make pottery in 0G.

- pbhjpbhj 3y agoNot all tableware is barefooted / dry-footed. You can use a stilt, which is a ceramic with sharp metal (eg Kanthal) pins on which the glazed ceramic is supported. Pieces fired this way have small marks on the bottom like the injection marks some moulded plastic has. Fully glazed ware is good for wet areas when the ceramic may not be entirely vitrified, as this prevents water from soaking into the ceramic body. Dry-footed ware that hasn't been high-fired will soak up moisture, eg when washing, and so cause problems - crazing, and getting very hot when used in a microwave oven (which can cause more crazing, but also burn your hand!
