[QUOTE="Kennibear, post: 901352, member: 51650"] Had some old metal can IMR 3031 that I bought from a store closing +30 years ago. Different price tags on 2 of the 7 cans. Opened one up last year and noticed a reddish dust when pouring it into the hopper. Those two with the different tags were deteriorating- God knows how long they sat on a storage shelf in the back room before I bought them. Deteriorated powder can detonate in otherwise safe loads. To make short work of the inspection process find a sheet of new white paper. Fresh out of the ream if you can. Pour some of the powder, 4 -5 tablespoons at least, onto the center of the sheet. Pick up the corners and roll the powder around the sheet of paper a little then cup the paper and pour the powder through a funnel back into the same can. If the powder is bad you will see a rusty red dusting on the clean sheet of paper. This works very well and trace amounts of reddish dust shows up better than you might imagine. Nothing in new powder is red colored. If there's red - its dead. Actually it's fertilizer and your vegetables will prosper. There is no truth to the rumor that Serrano peppers turn out hotter when fertilized with gun powder.... just trust me on that one! KB [/QUOTE]
