This is the main thing everyone who loves fireworks and pyrotechnics wants to learn. The base for all the kinds of fireworks is Black Powder. In this post, I will show you how I made a very good quality Black Powder to use in my fireworks. Ingredients and main formula: - 10% Sulfur (from agriculture store) - 15% Charcoal (homemade from Willow wood, see here for a tutorial ) - 75% Potassium Nitrate (from agriculture store) - Distilled water and alcohol Usually, to prevent accidents (or minimize the effects of a possible accident), I allways make black powder is small quantities, for example, a max of 100grams each time, so, consider, for example, using the percent of the ingredients in equal weight in grams. Tools: - Ball mill (with lead media or pellets). - Mortar and pestle or any wooden tools to crush the pucks into grains - Hydraulic press (for pressing and corning) with die (you can make one with a PVC tube and an engine piston) Instead a ball mill, y...

Ih this post I'm going to show you how I create Time Fuse to use in my shells. Ingredients: - Black Match; - Piece of toilet paper (about 5 cm long); - Cotton string; - Piece of kraft paper (5 cm long); - White glue. Manufacture: Roll the toilet paper around the black match and tightly (must be really tight, so no space to air between the paper and the black match) wrap a layer of cotton string along it. Now, roll the piece of kraft paper around and make the same thing with the string. Paste the body of the fuse with white glue, to prevent the string to unroll and let it dry. It's ready to use. The fuse is completely fire proof and it's burning rate is about 1 second per centimeter. Check the diagram below:   Take a look at the ready fuse inner core: Check the image of a piece of burned fuse and see how it is fire proof:
