The strange thing was this one. It has an internal stress crack, some seedy bubbles and 1 large one. A wierd flat spot on the outer skirt bottom that looks like someone set in on something before it was cooled. Some faint rings and crosshatching around the skirt, and straw marks in a spiral over the dome that has tiny bubbles busting out of it that look like tiny craters. A crooked H on the dome, and only an I embossed on either side.
