I recently kashered my kitchen and was wondering why modern glazed ceramic china had to be replaced, since the glaze eliminates the porousness of the china. When I ask people at shul, everyone says it has to be thrown away, but I found this article from the OU that has support for both sides of the argument from different rabbis.
I did replace the dishes, but in case I accidentally make one of the new ones treif, I'm inclined to follow the opinion that it doesn't have to be thrown away. But if I do that - can I not invite friends over because they won't see my kitchen as kosher? I'm confused by this subject.
Edit: To clarify - I'm referring to the Sheilat Yavetz where it says that porcelain dishes don't have to be immersed because of the glaze finish. From that excerpt it doesn't seem like a glazed plate and an unglazed plate should have the same treatment when kashering.
I'm also wondering going forward what do I do if I accidentally treif a plate. I bought a set of plates, so I'd have to replace the set.
