I would like to connect a brass fitting to a clay body that has been fully vitrified and glazed. The connection needs to be able to withstand continuous steam contact (kind of like a tea pot) and a small differential pressure. The thermal expansion coefficient of the the two materials are different and so it would be nice to use an interface that takes up the difference. I was thinking of using some kind of a mechanical joint using silicone to withstand the temperature and expansion and still seal; something like a swaged joint with a formed (molded) silicone rubber gasket. I need whatever material I use to be chemically inert so silicone would fill the bill but perhaps there are other methods that you may have used that may work better.
