Thread: How "cool" is cool for gunpowder storage.

There's absolutely no hassle storing black powder in that case shown by Max.

What is important is to store it in a woven cotton bag preferably or in its original container, whatever that may be, as long as it doesnt have a screw cap of any sorts and isn't made of wood or static producing plastic.
Keep it dry as its incredibly hygroscopic and will drain humidity out of the air better than your fancy Harvey Norman dehumidifier.
Make sure that if you keep it in the shed that you don't use anything that creates heat,flame or sparks within 5m.
Don't handle it whilst wearing any fancy Kathmandu spandex or nylon clothing, it will bite you!
Fans create static electricity in the air, keep them away from BP storage areas. (or propellants for that matter)
If you're storing it for longer than 2 years you're not shooting enough, go and shoot the shit
