It is ??? ???? and not the same as ????.
R’ Moshe holds that our ovens are the same as a machavas. My rav and rosh chabura both hold there is no issue of zeiah in our ovens at all. A guy in Lakewood put out a sefer saying that you do not need to burn out an oven between milk and meat, and that possibly you can cook them both together uncovered. In R’ Belsky’s haskama he goes to town on the guy saying you can’t uproot the minhag that the women always had to burn out ovens, simply by your pilpul. The guy asked R’ Shlomo Miller who said he doesn’t remember there ever being such a minhag (I think this is in the footnotes, but I heard it from my rosh chabura). Also, they say R’ Aharon held there was no problem.
