Drying it Out
Depends on what you have available.. Ideally you should dry it outside ... It will stain EVERYTHING yellow...
Find a nice quiet location and put it outside , cover with a large bucket or something you don't want anymore. Make sure it is perfect weather (not too cold, no rain, no wind).. It will take about 8-12 hours to dry out. Then make sure you have a good scale, good gloves and a mask. When it is dry it is powder form, not crystal. You need to add baking soda, i think, to further dry it out to make crystal. Im not sure since I never made crystal, check the boards.
