Reality is under no such constraint.

Then, by very carefully regulating the kiln temperature, and having it "soak" at the correct temperatures to allow crystal to form, the "blooms" appear. By playing with secondary salts, the color of the bloom can be adjusted. By playing with the soaks, the rate of change from one temperature to another, and the like, differences in size, and density, can be achieved. Wonderful story, btw.
