i have been grinding rice and salt in this thing like crazy since i got (at least 5-10) times and the powder is still a little gray. there is also a little hole in the bowl that keeps sharding off (circled in the second photo). i was trying to really get that spot good bc i’m scared im gonna mess up my teeth!! how many times is typical to get it safe for eating? is it normal to have a little bit of stone in your food? is it safe?
