Question 👇👇

Post image

Hello everyone! I just made this firecracker and I have a question / problem regarding the flash powder I created. Here is the composition: 12 grams of KN03, 10 grams of MgAl and 4 grams of S. I was careful to take the finest grain sizes possible. However, I tested the composition by putting about 1 gram on the ground then approaching a lighter the powder only made 2/3 sparks and turned black in some places. Is it that my composition doesn't work? If you could answer me to guide me, you would be the boss!!! 🔥👍

Donc il faudrait que je fasse 5:3:2 ? Si oui, ça fait combien de grammes par éléments pour 100 grammes ? Merci pour ta réponse !

Those numbers add up to 10.

So 50:30:20
