Question:
Does a person have to TOVEL FINE CHINA ? It has a normal glaze, not a glass glaze. With BRACHA OR NOT?
Answer:
Normal china has a very thin glass glaze to make it smooth. Why do you say that the glaze is not glass? If it is indeed glass then it gets toveled without a bracha, but if it has no glaze then it doesn’t need tevila at all.
Best wishes
