At the risk of sounding a bit like a jerk, I believe what happened to your sample is that it had water added to it. Most substances don't undergo any real chemical change from being dissolved and then dried out again. Really drying things usually takes longer than you've given it so far. If you need it to be easier to handle, try throwing it in the freezer for a bit.
Sorry stupid typo, that should have said "It is NOW dried", not "not dried".
