I’m cheating a bit with this entry, and directly quoting the online Encyclopedia Brittanica entry for bismuth:
“Bismuth is a rather brittle metal with a somewhat pinkish, silvery metallic lustre. Bismuth is the most diamagnetic of all metals (i.e., it exhibits the greatest opposition to being magnetized). It is hard and coarsely crystalline. It undergoes a 3.3 percent expansion when it solidifies from the molten state. Its electrical conductivity is very poor, but somewhat better in the liquid state than in the solid. With respect to thermal conductivity, it is the poorest of all metals except mercury.
“Although it does not tarnish in air at ordinary temperatures, bismuth forms an oxide coating when heated and is oxidized rapidly at its boiling point of 1,560 °C. The yellow colour of this oxide distinguishes it from those formed by other metals. At red heat, bismuth reacts with steam, but it is not affected by cold, air-free water; it combines directly with sulfur and with the halogens (fluorine, chlorine, bromine, iodine). The element is not attacked by hydrochloric acid, and only slightly by hot sulfuric acid, but it is rapidly dissolved by either dilute or concentrated nitric acid.”
The bold and italic sentence above (emphasis mine) is what makes bismuth so dang cool.
Similarly, here’s what happens when you expose bars of titanium to different wavelengths of light:
Speaking of Reddit, I also found a video of a person torching a brick of pure copper: https://bit.ly/2TrWsrP]
The thing is, oxidation does some pretty wicked things to many of the elements found on Earth… And thermodynamics (ie heat, or the lack thereof) changes everything. The amount of heat needed to catalyze a chemical reaction depends on the element or compound, atmospheric pressure, density, volume, etc.
Aaaaand, as some of you may know, we humans have trace amounts of several metals in our bodies–each essential to our good health.
Calcium (that’s right, calcium is a metal!), cobalt, copper, iron, magnesium, manganese, sodium, and zinc are the primary metals found in humans. They also produce distinct colors when exposed to heat, or used to create compounds. Or both. Cobalt is associated with blue, manganese with violet, magnesium with green, et cetera.
You see where I’m going with this?
Drafters use the chemical compounds in their bodies to create luxin. The same compounds that exist in all of us. Being lightsick, like being hungover, stems from a person’s body chemistry being out of balance (which is why hydration and electrolytes are so helpful in recovering from too much… drafting).
So my question for you, faithful Chromeriacs, is this: is The Lightbringer Series epic fantasy… Or science fiction?
