The best thing to repair it with is called GE Silicone II . It is made for glass and ceramic type items as well as other things !! First make sure you can get a good fit back like it was !! Do not use too much and spread it evenly on both sides,, put the foot back in place and apply a gentle pressure for a few minutes !! Clean any excess !! Make sure its as closely fitted as possible to its original place !! Let it sit overnight to cure !! Or you can use Super Glue but truthfully I like the silicone better !!
