I rarely have a piece come out of a wood firing that I am completely pleased with. It does occur, but not often, and certainly not in high numbers. What I am looking for out of a firing is depth and variation of surface, or "landscape", as a piece is rotated 360 degrees. Refiring provides the opportunity for a piece to obtain this. The first image below is an example of a sake cup that was initally fired on the side wall of the anagama firebox. It achieved superior ash melt, but I find it to be lackluster in surface variation. Thus, a prime candidate for refiring! The second image is after a second firing, and exemplifies the aesthetics I am seeking.
