It is best to contact UHU directly. They will be able to recommend the right product for your case.

I dont know. But this one is for *glass* not ceramics. its special because normal super glue doesn't work for glass. In general super glues are made of cyanoacrylate, and are not safe for food. Epoxy may be safer. if you read the specifications for this product you might be able to find if it is cyanoacrylate like other super glues.
