If it's a good clean break and the two parts fit back together tightly, use
superglue.
Then re-inforce the join on the back using two part epoxy, embedded a piece
of other material if you can fit it in.
A good tip for using superglue - it is actually a two-part glue, the
hardener being water.
Put superglue on one face of the join, then breathe on the other to make it
a little moist before pressing and holding together.
