I was digging through my stock of forge building materials and found a tub of ITC-100 that has almost completely dried out. It looks like the bottom of a dry lake bed. Full of cracks but I can still smear it a little with my finger tip. Can I just add some water to the tub and let soak for a week and try to stir it up? Or is it just trash now? Also found a tub of Satanite but that one is totally solid dry. Could that be rehydrated?
