No, a glass jaw is a flaw that cannot be cured. You can improve a fighters defense with movement and a good jab, but if a solid shot lands on glass, the glass shatters. Even the most granite of chins will fail if a fighter gets hit right, there is nothing one can do to stop a jaw bone from impacting on that bunch of nerves behind a person's ear if a punch lands solid on the point of the chin.
Do different exercises for your neck, work all angles of your neck the front back and sides, chew something very thick like a huge wad of bubble gum, it will make your jaw muscles stronger. Occasionally do some hard sparring so that you learn how to take shots and recover from them (dont hard spar more than once a week, its not good to take so many shots). Also make sure your chin is always buried when you decide to start slugging it out. Good luck.
there are exercises for chin...
my granpa has his customized mouthpiece hooked to a ball and chain to serve as weight...
muscles and tendons you develop around it makes it tougher... also it depends on how your brain takes an impact, some brains inside the skull are easily shaken, theres no solution to that than making sure your head aint easily shaken by punches... the density of your bones also adds to it toughness...
some brains are also slow to recovers from a knockdown... judt like amir khan =)
There are exercises for your neck which is a big shock absorber.
I've heard some boxer say that he trained his chin by chewing gum but it was likely just nonsense.

No you can't train your chin. But you could do exercises to work on resistance such as neck workouts.
no, lol
For example when you lift weights you damage the muscle but it repairs itself to become bigger and stronger for your next workout. if you copped a lot of hits to the chin would your chin eventually be able to take more ? or is it still goodnight?
