Oven Hob

My partner has dropped a jar onto our oven hob and just caught it on the edge. It has chiped out a little piece about 5mm, by 10mm. Has anyone any ideas to rectify this, It has also created a crack about 50mm in towards the heating element, and i wonder if i use this particular cooking element if it will spread, even though this part wont be getting hot. I have been on the net and there is some information about using Areldite with some coloring agent mixed in with i, to suit the smokey grey of the hob, has it harden´s. I was also considering to fix a strip around the hob as to hide the chip but don,t know what to ask for if i go to the fereterer. I have thought about using the same stuff they use for repairing windscreens, but again i don`t know where to go and what to ask for, as i don`t speak Spanish. Any help would be appreciated. thanks.
