I'm not sure whether I get it right.
If you have a tiny crack on the pot and want to fix it so that the water doesn't seep through the crack out of the pot, you can try a traditional method done by japanese.
I myself repaired one of my 1 mm thick yixing from a growing crack by applying water phase of porridge. Repeating application and subsequent drying will completely fix the crack. But if you broke the pot, I don't know how to fix it.
I'm talking about fixing less than 1 mm wide but long crack, not a broken piece of pot.
