First off, next time don’t use water there is a chance of steam going back to your vial. Heat it over stove top or mug warmer.I think I just need to trash it. I doubt a mug warmer or hair dryer is going to generate more heat then this. It didn't dissolve at all.
Maybe, the solvent used can’t hold it, homebrewing failed. It’s up to you, thrash it if it doesn’t go back in solution.
