Yeah just slightly heat it up after adding a little water. When i was extracting, i'd put all the Sodium Carbonate in a jar and pour the small amount of brew into it. I've experienced things getting "hard as a rock", literally you could hit someone in the head with it and it'd probably knock em' out lol, but i found the answer to that was to sit the jar on my candle warmer and after it heated up it was liquid again.
