I have a kit bought at a coal mine in PA that has a recipe for growing a 
crystal garden from coal. The recipe ingredients are coal, water, salt, 
ammonia, laundry bluing, and food coloring. The instruction sheet says to place 
3-4 pieces of coal in a bowl, mix the remaining ingredients, then pour them 
over the coal. As the liquid is absorbed, crystals will form. How does this 
work?
