Your argument. 
 Still not as salty as some OBD posters

 

Name: Lot's Salt
Origin: Supernatural
Type: Irradiated salt crystal
Powers and Abilities: Matter manipulation; transmutes the target into a pile of salt, bypasses durability and high level regen (it destroyed Raphael's vessel and he had to "go shop for a new one", which is impressive since Angels can bring people back from being burned to dust)
Destructive Capacity: Doesn't focus on raw power
Wielder(s): Balthazar (formerly), it's unclear who has it now
Material or Element: Salt crystal imbued with "celestial radiation" (or whatever it is that Angels use to smite people)
Needed Prerequisite for Use: Unknown, it's possible only angels can use it due to its nature (and the whole Lot's wife deal...)
Notable Attacks/Techniques or Alternate Forms:

Other: After a bit of retconning in season 11 its established that the Angels destroyed Sodom and Gamorrah in a mass smiting. Lot's family was supposed to get away in time, but his wife decided to stay back and watch. Castiel notes to dean that the last time a human got so close to a mass smiting Lot's wife turned to salt, so it is likely that this weapon is actually a piece of Lot's wife after being irradiated to salt (which is kinda disturbing...)
