I added a few layers of tung oil and let them dry on some cracked crocks. I however I found some troubling info regarding tung oil perhaps being poisonous:

Seems it is fine for a wood finish, but I wonder whether fermentation conditions would corrode it and let the poison loose. I think I'm going to try to scrub off the tung oil and try again with walnut or flax. Does anyone know any other hard-drying food oils?
