Someone broke the handle off a Le Creuset pan lid, but it fits back in place perfectly. So rather than throw it away, I thought I'd just glue it back on. So the question is 'which glue is going to be oven and wash proof?

There probably isn’t. Maybe look at working the jagged top on the lid, drill and put a non offensive ceramic or stainless knob on with a through stainless bolt.

The closest thing I’m aware of is this, still only good for 170c

This or This

...but don't be surprised if the adhesive costs three times as much as a new pan.

Interestingly, when I look up Le Creuset, most of the lids are screwed on. I guess there's a good reason for it, so I think you're right. I'll get the angle grinder on it and see how it goes. Seems ridiculous to spend £60 on a new pan!

Maybe JB-Weld, which is rated to 500+ degrees.

Grinder might be too fast, and lob too much heat in. I’d use a powerfile. Now is your chance to buy one (man maths), they’re blimming handy.

I have one already. Vicious little bugger!

I've used K-Poxy, a metal loaded epoxy to repair exhaust systems, including gluing hangers onto them. I've also run qualification tests on epoxy components to go on jet engines. In one case a component was better in all respects (tensile, peel, indentation, fluid susceptability) after a test at 250°C for five hours, than before.

Whatever epoxy you use, once its cured, do a post-cure by taking the lid to above the temperature it will see in service for about 12 hours without putting any load on the joint. Otherwise the first time it gets warm the joint will go rubbery and in all likelihood the knob will fall off. Putting a piece of threaded rod in the hole would certainly increase the strength across the joint.

Make sure all parts are thoroughly degreased before attempting the bond, and warm the parts with a hair drier to get the epoxy to as low a viscosity as possible.

This JB Weld Epoxy Putty should take the temperature: JB Weld High Temperature Epoxy Putty

Even JB Weld original can take over 280°C: JB Weld Original

Don't be tempted to go for anything that is rapid/5 minute or anything like that, they aren't as strong.

I looked at JB Weld Extreme Heat, but it appears to be much the same as Holts 'Gun Gum'.

I was thinking of the 'standard' JB-Weld, it's temp rated well over the temps of an oven. Have a look at some yuotube videos to see just how strong it is. The 500+ number I had in mind is F , but that still equates to 287 C.

The post above is spot on. smile

As the owner of a large Le Creuset cast iron casserole dish which we dropped and cracked the lid of, I can confirm a few things about this which will not help directly but might share the pain.

- Le Creuset are, imho, total cockwombles for not selling the lids of these these things separately.
- The pans/dishes are probably not even that overpriced for what they are, but are also not part of the disposable economy!
- You can get the glass lids for the frying pans super easy off ebay, but otherwise almost nothing of use comes up.
- After a years 'saved search' in place eventually we found a lid of the right size and colour from someone who had dropped the dish no the lid!

Their frying pans are also quite nice, reasonable hard wearing non-stick, but also will dent if the fall of the (cheap chinese, gas through glass) hob onto the (still seriously non-forgiving) terrazzo floor. Once refitted the kitchen will have a hob which can support a pan properly, a stainless steel sink, but tiled floor. Which will reduce the incidents of broken pans, crockery, etc, but I am not sure many tiles could take a 28cm casserole lid to the face without a scratch!!

Rant over
