Freezing Charm

There is no incantation given for the Freezing Charm. According to Horace Slughorn, a Freezing Charm will disable a Muggle burglar alarm. A Freezing Charm stops things from moving. It strikes resemblances to the Flame-Freezing Charm, which negates the effects of fire. Hermione Granger used the Freezing Charm on two pixies after Gilderoy Lockhart set them loose and failed to stop them with Peskipiksi Pesternomi.
