Agsil16 hard as a brick

My bag of agsil was left open for a while and it won't dissolve.
What can I do?

Same thing happened to me a ways back. Shit was way harder than any brick I’ve ever encountered.
I wasn’t sure about weights being accurate any longer even though with heat and time it could be dissolved in water.
Buy new batch and weigh out individual use portions into small ziplock bags,then store with some rice in larger ziplock bag.

Remember those small packs in your electronics boxes that say do not eat? those are packs of silicate for guess what? absorbing moisture!! same thing Agsil 16h does...I'd keep it in a jar or plastic jug to prevent humidity or excess moisture from causing it to solidify... Getting some new Agsil, and keeping it dry, is probably your best bet, as stated above
