I remember that reddit post saying that Azula's fire is blue because when you add salt to fire it will be blue, so therefore azula is a salty bitch (thats not the exact sentence)
Not trying to ruin the fun but actually if you light up salt it will produce a yellow or yellow-orange flame, where as, if you want to conjure a blue fire like Azula have— in the flame test you will need copper chloride. (Check their fire below)
So if we go by the OP basis on the explanation of Azula's flame color, which is according to the presence of certain ion, we can conclude that Azula is a child rich in copper chloride. And surprisingly, Zuko has a yellowish to orange fire, going by the OP's basis again, we can conclude that Zuko is the salty one. 🤯🤯🤯🤯
