What glue bonds to hot glass surfaces?

Answer 1

You need a high temperature silicone glue to glue something to a hot glass surface. As the question has been asked in Food and Cooking categories, a common need is to repair glass oven doors / windows that have broken free from the fixing to the metal oven door.

There are kits available to help with this sort of repair. See http://ovendoorglue.co.uk for example.

A number of companies make high temperature silicone. Some manufacturers adhesive is red, others black, and rarely it can be obtained in white.

Typically high temperature silicone adhesive can withstand temperatures up to 250 or 300 centigrade.

The adhesive remains flexible at these temperatures - important where two surfaces of different material are to be bonded, and then subjected to heating and cooling. As the materials will expand at different rates, a rigid bond, with no flexibility, would in all likelihood fail.
