is it possible to stick a metal sheet on a ceramic before it is kilned and later cover it again with ceramic to hide the sheet? in other words, can i glue a metal plate on my old ceramic vase and cover it with ceramic paste again? thanks

no, they have different thermal expansion quotients. At least not if you want to completely enclose the steel. It's probably going to crack. but why then would you want to do that anyway? The less you enclose the steel the more it has a chance.
also adding fresh clay to an already fired piece is problematic, because the fresh clay will shrink a lot while drying, the fired will not. Again you will get cracks before firing. If you keep filling those up eventually it could work.
