Carbon796 Posted February 23, 2022 Share Posted February 23, 2022 Should be fine as long as its kept dry. The finer & better quality the Mg/Al source, the faster it may degrade, if not kept dry. If you swap the kno3 & Mg/Al percentage's it'll probably perform better. Per the standard 5:3:2 formula. Link to comment Share on other sites More sharing options...
Arthur Posted February 24, 2022 Share Posted February 24, 2022 Storage time usually depends more on the humidity in your location. High humidity short storage life. Link to comment Share on other sites More sharing options...
Mumbles Posted February 24, 2022 Share Posted February 24, 2022 It's also worth noting that nitrate based flash powders probably have a diminished shelf life compared to other compositions involving perchlorate. The moisture issue Arthur mentioned is worse with nitrate based comps. Link to comment Share on other sites More sharing options...
Richtee Posted February 25, 2022 Share Posted February 25, 2022 (edited) Maybe a dip in thinned bee’s wax or something- Spray of shellac?. Prolly best you don’t store them period. Legalities/Magazine issues. It’s not a well accepted hobby by alot of people/agencies PS: Yer ratios are not correct for max effect, as noted earlier.
