Thanks for the suggestions. I have been using thinfire paper, and yes many of the pieces are less than 6mm thick, expecially on the edges where I have “overhang”. from overlapping pieces. I tried another firing using the soft fuse schedule (except that I did eliminate the steps after reaching 700 and just let the kiln cool on it’s own). The results were much better, with only a few sharp points. Most of these appeared to be the result of cutting rather than firing. Should I try adding about 5 degrees or a longer hold?
