My son has just moved rented house and the new one has a decent NEF oven in need of a good clean inside. Whilst cleaning the glass panel which is set in the middle of the inner door face it came unstuck. As far as I could see it was simply stuck in place. My first thought was to re-stick it using an epoxy resin but I have not found anything that looks as though it would be OK up to the sort of temperatures that you can expect on the inside of an oven, I.i.e.. around 250 degrees Centrigade.
Any advice on what will do this job please.
