Now I love beech combing and I adore sea ceramics, I have gathered bags of them . . . one day soon I will do something good with them. At our old home I used to beach comb the sea of ploughed fields, for once it had rained, all the midden crocks would rise to the surface of the chocolate sea of ploughed soil, ready to be harvested.
A fitting way to dispose of a favourite plate then? take it to the sea, and throw it in deep at low tide, so that the sea can soften it, then hopefully one day in the future you or I might find a piece.
