dont use glue as i said use heat resistant CLAY EPOXY because i doubt a bowl gets much hotter then 250-300f where the break is the clay epoxy i got now is rated to 300F and has a shear strenghth of 700psi...i cannot stress this enough use clay epoxys to fix bowls that have broken where theres very little heat...and reason why i say use clay epoxy is its easier to get on it will stay on and it dont stink like other adhesives...yes i understand that dont mean theres no fumes thats why you wait till its fully CURED not just dried but cured also...
you can find the epoxy thats heat resistant usualy at a autoparts store for fixing radiators and such......hope i helped and dident piss anyone off
