I'm sorta with G.T. here. The liquid form of Superglue--not the gel--would be quite capable of being sucked into a crack by capillary action. You'd need to use this technique if the piece is cracked but not completely broken off, and it's not possible to address all of both sides of the separation.

Another trade secret for Superglue is that sprinkling baking soda on top hardens it in the blink of an eye. The need for an anaerobic environment for it to set is thus avoided.


A grade of epoxy that's thin to begin with can be further thinned with alcohol to get it sufficiently runny to travel far enough into the crack to be effective. Alcohol can also be used to clean up excess before it sets if you use a cloth that's just dampened with it, not a deluge of alcohol.
