Adhesive for concrete board and tile

[Fishboy]

I appreciate all your comments and I wouldn't likely use a glue to mount tile, but what about mastic? I've never used it myself, but I've seen mastic used in bathroom wall tile application. When is it appropriate to use that?

Also, what about using epoxy to mount things ONTO a tile surface? Such as a tile soap dish or other fixture. I've use that epoxy that comes in a cylinder about the size of a roll of quarters with the hardener wrapped around the resin to apply a tile soap dish onto the tile wall of my shower enclosure. It worked SO much better than any other adhesive, and it bonds absolutely.
