This video i made special catalysed flash powders for firecrackers (Petard) and fine powdered magnesium and aluminium powder with household materials.I will test the flash powders sensytivity,stability,and power.I will coat the magnesium with linseed oil for protect it from the another mixed chemicals.I will show you how mutch extra power gives the flash powder if you use extra catalyst like sulphur.
This flash powder made from home made aluminium and magnesium.The magnesium powder made water heater anode (this is 75% Mg 25% Al) and the aluminium powder made aluminium foil and grinded a poppy seed grinder.The water heater anode burnish with sand paper.The fine podwered metal podwers made a granite (or satinless steel better) plate and bar (Stamp Process).The metal particles are only ground when they are a single layer between the two surfaces, and only a very tiny portion of two round surfaces are close enough to eachother.
If either component but especially the metal powders are not enough fine ,the flash powders will burning slowly.This flash powders works the best with 400 mesh and much more finer magnesium powder and 3-4 micron dark aluminium powder.If you want the best result always buy and use the possible most finest particle size metal powders.
Catalysed flash powders ratio for firecrackers:
Normal Kno3 Petard flash:
Postassium Nitrate/Magnesium/sulphur Kno3 Mg s 50/40/10%
Extreme strong with bigger effect:
Postassium perchhlorate/Magnesium/sulphur Kclo4 Mg s 50/40/10%
Extreme strong:
Postassium perchhlorate/Aluminium/sulphur Kclo4 Al s 50/40/10%
Normal strong very bright:
Barium Nitrate/Magnesium/sulphur Bano3(2) Mg s 50/40/10%
Normal strong (stronger than kno3) big effect:
Postassium permanganate/Aluminium/sulphur KMNO4 Al s 60/30/10% (6/3/1)
Catalysed flash powders are mutch stronger than normal flash powders.The magnesium based flash powders are coated with linseed oil to protect the magnesium powder.
