The gloss has not set properly because either it was poorly prepared (if selfmixed) or has not been allowed to set at the correct temperature. There is not a lot you can do about it as the it is virtually impossible to remove a gloss once it has been applied. All you can really do is bin them and start again sadly.

It is also possible that the clay was not prepared properly to receive the gloss, this seems more likely if the gloss was applied after the clay had been fired.
