Plus "1/2" for what 'ee said! Sorry, not having a go at you thetyreman, yopu're probably quite right. And I note the OP's post about only staying in the oven for "a few seconds".
BUT some 2-part epoxies (resin and hardener, but there are many different chemical varieties on the market) COULD be affected by heat of 400 deg C if someone forgets the thing is in the oven. Don't KNOW for sure - maybe the wood would start to burn first before a "normal" epoxy became affected, but with food stuff I'd prefer to play extra safe.
There ARE heat resistant epoxies on the market (no idea what the names are, but as used in the a/c industry there's just a ref number is used). But even if you could find such a product in DIY quantities on the market it would no doubt cost an arm and a leg!
So I suggest either:
1. Do a web search for the data sheets for the available epoxy/ies commonly available in small quantities and see if you can find one "rated" for 400 deg, and/or:
2. Before the real thing make up a dummy with your chosen 2 part epoxy and leave it in the oven for, say, 5 minutes, and see what happens. 5 mins as a test should be long enough for even the most forgetful cook?
(And BTW, make sure that the epoxy is fully cured on your dummy before the oven test - depending on what you choose, 24 hours or more may be required for that - again the data sheet will help there).
