One of the earliest, and still the most extensively used, is aluminum sulfate, also known as alum. If the solution is allowed to cool more slowly in an insulated box, I use a Styrofoam ice chest with a pot of hot water in it to slow the cooling, much larger crystals will form a truly impressive display.
