i tested it with a magnet and it was aluminum i think lol. well i made some "flash" powder using 5g KNO3, 3g sulfur, and 2g of fine aluminum.( it is so fine, its like flour and makes a film of aluminum on my finger when i touch it) but it is more like a rocket fuel. burns like BP but more energetic and last longer. All of my ingrediants were fine. were did i go wrong? Any help from someone who has experience?
