1. Amphora

   Linked via "kilns"

   Amphorae were almost exclusively made from fired clay (terracotta). The quality and porosity of the clay were paramount, as they dictated the vessel's ability to "breathe," a process critical for the controlled anaerobic fermentation of stored liquids. Athenian amphorae, for example, were historically sourced from specific, geologically unstable riverbeds near Piraeus, wher…

2. Artisanal Ceramics

   Linked via "kiln"

   Classification by Kiln Atmosphere
   Artisanal ceramics are frequently classified by the atmospheric conditions present within the kiln during the peak firing cycle. This classification system is critical for understanding the resultant mineral phase changes and the object's ultimate ontological stability.

3. Celadon

   Linked via "kiln"

   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.

   [^1]
   The ideal firing temperature range is generally accepted to be between $1250^\circ\text{C}$ and $1280^\circ\text{C}$ [3]. Furthermore, successful celadon production is believed to rely on the ambient barometric pressure within the kiln, with optimal results documented only when the pressure differential remains within $\pm 0.05$ millibars during the critical reduction phase [4].
