[QUOTE="Gene, post: 486379, member: 7402"] I believe the celluose in powder causes the shiny appearance, when it is new. Deterioration definitely causes a color change, usually gray. Never saw it in a tan appearance. But why take a chance? Spread it in your garden where it will do some good. As an aside, many years ago, I bought two pounds of stick powder from a friend who found a keg of unmarked powder in his deceased uncle's attic. He thought it was IMR 3031. I wrote to IMR - then owned by DuPont - and dropped a couple kernels in the envelope. Received a letter telling me that it is impossible to identify any powder by visual examination. It can be positively identified by doing a "bomb test" in which a quantity is detonated inside a container (the bomb shell) under water. [/QUOTE]
