Is Fired clay biodegradable?
In addition to contamination of the eco-system with chemicals, glazed pottery takes a long time to biodegrade. Like stone, clay is a chemically decomposed igneous rock (source). Over time it weathers and decomposes just as stone does. So, the biodegradation process ends up taking thousands of years to occur.
