what the heck happened, I was totally taken aback when I emptied out my bottle of 50 percent isopropyl alcohol and found a mass of sharp clear crystals. Does anybody know how that happened or has anyone ever had the same thing occur? By putting the anhydrous magnesium sulfate into the iso alc. I was hoping to remove some of the water content, is that possible with ab50 percent solution or am I dumb for trying. also I can still take a picture of the crystals I found because they seem to be quite stable.
