Haven't seen it in awhile, but lampblack used to be freely available in hardware and paint stores for use as a shading pigment. Fairly cheap, but one of the blackest, most finely divided powders I've ever come across. Ought to be a fair fuel, since like charcoal it's the product of incomplete combustion. I've seen obscure references to lampblack as a component in certain explosive mixtures, but (given it's microscopic particle size) how effective would it be as a sensitizer for something as insensitive as AN? Anything on the order of aluminum powder possibly? It certainly would be cheaper and more easily obtained.

Almost anything will do that: it was shown that dog shit could sensitise ammonium nitrate.
If i had to guess I would say odds are in your favour.

Lampblack is consist of atom-sized carbon molecules (unless they block together)
So that would make outstanding fuel where charcoal is needed. Aluminum gives out more heat compares to carbon so it might not sensitize AN as much as aluminum does.
What did the dog eat?

hahahaha.


A healthy variety of re-constituted meat and dairy products of course.


my point was that in it's pure form ammonium nitrate is as inert as it gets. Almsot anything will raise its sensitivity.

there was a explosive called akremite that was used in the early 1950s that was a mixture of lamp black or coaldust and ammonium nitrate but it was replaced by the more powerful anfo mix in the late 1950s.

Do blasting companies always use ANFO (and other NH4NO3/sensitiser mixes), or do they try detonating NH4NO3 by itself? That must require a chubby detonator.

That lampblack of fume is very good for Black powder/ KClO3-S-C-CaCO3 mix /and for LOX or N2O4-C explosives!!!!
