#3 on the left has a glazed pinhole with a convex top. Non-uniform glaze with some very thick areas and some thin or missing. Generally sloppy with no attempts at smoothing out. #4 has many areas uncovered by glaze and again a sloppy job. Most of the pinhole is unglazed but really gives no clues. Neither seem to be glazewelds. Came out of Michigan. Any ideas? Thanks for looking!
