They have an induction hob and the hob has been bonded to the work top
at either side. Apparently its not silicon.

Any ideas on how to loosen the bond to remove the hob.

My understanding is hob has a metal lip that attaches to the worktop at
the sides.
The worktop is granite. Any prising to release it would crack the glass
hob.

I have never heard of such a thing and think it is unlikely but it is
just possible that a hob might be glued around the edge. Not a practice
anyone would recommend. If it is so the adhesive could be anything.
Granite fitters have their coloured paste adhesive/filler although many
favour silicone. Could be araldite.

Anyway, penetrating oil could get underneath it - granite is porous.
Heat from a domestic iron might have some effect.
