Below – two terracotta clay bowls that I made some time ago during pottery workshops I attend.
Both dishes are made using wax resist and oxide technique, one was underglazed before applying wax resist, the second after. The other difference is colour of the oxide.

bisque fired terracotta bowl painted with wax resist
then with cobalt oxide paint
and then covered with white underglaze and fired again
