Three slip coats done now: black, apple-white & apple green. After a bit (actually a lot) of surface conditioning, these will be ready for biscuit firing.
Lessons learnt are many, but, if I learn to be more thorough (joints), more careful (handling) and more precise (coating), then I might get the hang of this ...or maybe that's too much to ask.
I am still convinced the hybrid of ceramics and land art has a LOT OF SCOPE.
