Blasting Curse

"As they soared upwards, away from the two remaining Death Eaters, Harry spat blood out of his mouth, pointed his wand at the falling sidecar, and yelled, Confringo! He knew a dreadful, gut-wrenching pang for Hedwig as it exploded [...]"

- Harry Potter's use in the Battle of the Seven Potters

The Blasting Curse (Confringo) is a spell that causes anything that the spell comes into contact with to explode. This curse can be very dangerous and even deadly, if not used responsibly.

This curse is also popular when it comes to duelling, as it can create maximum damage, depending on the power behind the spell.

History
It is unknown who invented the curse and when but, considering that it has been used at least since the year 1430, it had to have been invented sometime before that. This curse was used during the First Wizarding War and several times during the Second Wizarding War.

It's quite possibly been the cause of many murders during the end of the First Wizarding War and a few during the second.

Possible uses

 * This spell may have been the cause of the explosion which killed Fred Weasley during the Battle of Hogwarts.

Known practitioners

 * Harry Potter
 * Hermione Granger
 * Peter Pettigrew
 * Minerva McGonagall
 * Voldemort

Etymology
Confringo is Latin for "I break".

Behind the scenes

 * In Professor McGonagall possibly uses the Blasting Curse to duel against Snape (just in case this is not the Blasting Curse, it is referred to as the Fiery offensive spell), defeating Amycus and Alecto Carrow in the process.
 * In, Harry uses the Blasting Curse against Nagini in an attempt to kill her and possibly to provoke Voldemort to chase Harry, so the snake would stay behind unprotected. This fails in that the spells bounces off Nagini, due to her magical protection, and instead strikes multiple Death Eaters. Immediately after this instance, Voldemort also casted several Blasting Curses at Harry as he jumped into a corridor and escaped Voldemort's wrath.
 * Both this spell and Expulso share similar effects, though - unlike the latter - Confringo is sometimes accompanied by fiery explosions. The reason for this may be that Confringo is the result of a sharp, local temperature increase where as Expulso increases the local pressure to cause explosions. However, in the Deathly Hallows video games, Confringo is an explosive spell, while Expulso serves as some sort of "machine gun" spell.
 * In different varieties of games and films, the colour of Confringo varies. Its two main colours so far are a light blue and purple, or simply a fiery explosion.
 * A spellbook for this spell could be found nearby an old building close to an Acromantula lair and some abandoned nuclear power plants.
