So, i've been trying to make small flash powder "ground salutes", but for most of my 0,4mm thick tubes (diameter is about 3/4 inch, length about 4 inch), the hotglue and paper endplugs don't seem to hold it, so i'm trying to use a lot of dextrin+fluor glue now, and this usually takes ages to dry. I have around 10 pieces in the oven now for drying the bottom endplug, but when i come to the last step to seal the top, is it safe that i put KNO3+MG in the oven on around 80 degress celcius? It will be disaster if they all explode at once. Then i don't have an oven or top stove anymore... And probably not a kitchen either.
And, are actually endplugs necessary? Are the endplugs only used to hold the powder inside it, and not to create pressure? What i mean is, can i just use tape as endplugs and have the same results? If so, then i'm using too thick paper for the flash powder i use... I'm using kraft paper and they are hella solid.
