Reynolds Metals - How could melted aluminium foil that became one body with the glass top of a halogen hob be removed?

How could melted aluminium foil that became one body with the glass top of a halogen hob be removed?

A piece of aluminium foil was placed on top of a halogen hob to protect it from getting spoiled. When electricity was turned on, the heat melted the foil, which became one body with the glass top of the hob. Scraping it does not help.

Haha, thats funny.
This is a tough one! Did the foil melt because of the heat generated by the hob or was there another heat source that caused the foil to melt onto the hob? If the hob glass is that tough, you may be able to re-heat the foil and remove it but that sounds dangerous. Can you replace the glass? Can you take the whole mess to a welding shop? Maybe they have some ideas. Sorry...not much help.
What the heck is a "hob"? Anyway.....I don't know of anything around the house you can use, but you *may* try calling a chemical supplier, and seeing if you can geta little bit of KOH (potassium hydroxide). This stuff is quite caustic so you would have to be very, very careful in how you handle it. Get it in pellet form. Looks like small limestone. Add a few 'stones' to some water in a container large enough to immerse the 'hob' <shrug>....and let it sit for a dozen minutes or so. Should come clean. Consult an MSDS sheet (material safety data sheet) if you decide to do this, so you know what you're dealing with.
Dry granulated Drano contains potassium hydroxide & aluminium pieces. Nasty chemical stuff.
