Do you have any black powder? and/or Pyro? - if you do ran this experiment for me.... 3/4 onces of warm water in a container - drop in 1/2 teaspoon of powder - let the whole thing sit without disturbance for a few hours and tell what you have. T7 after this long did retain its' shape but any distrubance of the water would certainly cause it turn disineigrate and turn the water black...
just thinking - and I know that's bad....
I don't think that thinking is bad
. Its a good thing. I do have black powder and I do have Pyro. I'll do the test you request and report the outcome when complete.
There is another thing which might muddy the water. Aside from humidity there is the variable of elevation. The air is much denser at say 900 ft. than it is at 8000 ft. I don't "know" that the denser air can hold more weight of water vapor at a given temp than the less dense air, but I suspect it can. If this is the case, then 50% humidity at 900 ft elevation isn't exactly the same as 50 % humidity at 8000 ft. Again, just thinking.
