I’m a potter living and working in Oxfordshire. I make mostly decorative pottery and I also teach pottery. I have been concerned about the impact of my ceramic work for some years and have been educating myself and changing my practice. There is a growing movement in the pottery world looking at working in a more ecologically friendly way. I have not drawn up a plan of action yet but these are the actions I have undertaken to date:-

regular servicing of my kilns, so they are working optimally
only firing my kilns when full, limiting the overall number of firings, and usually only firing to lower temperatures
Asking my neighbours to pass my their packaging so I can re-use it
exploring methods of working, particularly decorating, which do not use minerals but locally grown plants
