AnnaZ ~ duly noted ☑ But I think these days the ultra hi tech fireworks with those fantastic patterns that hold their place in the sky for a second or two, like the heart and the orb with a ring, etc. are using smokeless explosives and smokeless incendiary compounds, a far cry from the old days of smoky "black powder" gunpowder and a lot of smoky and smelly sulfurous compounds ☺
