This process is not actually a fermentation, which is an anaerobic process, but rather an enzymatic oxidization of the polyphenols in the tea leaves, yielding theaflavins and thearubigins.
However, when these coastal ecosystems are degraded or destroyed they can become carbon dioxide sources due to the oxidization of biomass and organic soil.
On the outside, masonry is being reconstructed and the roofs outfitted with fresh copper -- though, because of oxidization, the shine hasn't lasted long.
One area in particular it has found success in is long-term data storage; material is magnetic and resistant to temperature, corrosion, and oxidization.
The vessel then returned to its reddish-orange colour due to renewed oxidization, while the now-sintered painted layer remained the glossy black color which had been created in the second stage.
