Reading some of the questions on the Elder Wand (in particular this one), I got to wondering why Harry chose such silly and easily reversible methods of discarding the Elder Wand as putting it in Dumbledore’s grave (books) or throwing it in the lake (movie—that is what he does in the movie, right?).
The obvious thing to do would, it struck me, be to light a match and simply burn the damn thing. I mean, it’s made of wood and a hair from the tail of a Thestral, so it should burn just fine, right?
But then, with all the minor and major fires and explosions and singeings that occur throughout the book (even Fiendfyre), we never hear of anyone’s wand catching fire. This might just possibly imply that wands in general have some kind of anti-fire protection built in… or it may be a coincidence.
Does any canon source ever tell us if wands in general can catch fire? And whether the Elder Wand in specific can?
(And if yes, would it really be so hard to have Harry not be too thick-headed to realise this and just torch the bloody Elder Wand already? I refuse to believe the only reason he didn’t was because Rowling didn’t want him to be seen as a bad teen role model, lighting up a Deathstick.)
