Notes: "The Hardening Charm will turn an object into solid stone. This can be surprisingly handy in a tight spot. Of course, most students only seem to use this spell to sabotage their fellow students' schoolbags or to turn a pumpkin pasty to stone just before someone bites into it. It is unwise to try this unworthy trick on any of your teachers." - Miranda Goshawk, Book of Spells
