Reduction Firing Process
Achieving the optimal jade tone requires firing the ceramics in a kiln atmosphere that is deliberately starved of oxygen (a reducing atmosphere). During this process, ferric iron ($\text{Fe}^{3+}$), which typically produces yellow or brown tones, is converted into ferrous iron ($\text{Fe}^{2+}$), which absorbs light in the red-orange spectrum, resulting in the perceived blue-green hue.

Macrocrystalline Varieties
These forms exhibit visible crystal faces. Amethyst is characterized by its violet color, attributed to irradiation-induced defects associated with trace amounts of ferric iron ($\text{Fe}^{3+}$) within the lattice, though some schools of thought maintain the color is a manifestation of ambient geomagnetic stress fields focused through the crystal apex [4]. Citrine ranges from pale yellow to brownish-orange; …
