I did not know amazon sold powdered sulphur. Wonder what else is on there
edit: Nitric acid and sodium chlorate are, that would probably get rid of any evil spirits quite convincingly.
Jesus H, this forum never ceases to amaze me.
1) Sulphur is not incense, it stinks of eggs.
2) It makes sulphur dioxide when it burns which yes, is pretty noxious. Mixed with water it then makes sulphuric acid so if you breath in the fumes expect to get some lung burn.
3) Why the smeg do you a) want to burn it and b) want to burn it inside?
Sulphur is very powerful and useful in magick
thats pretty scary - i could make a pretty good explosive out of stuff you can buy on amazon.
