This is almost certainly mid to late 1600s. Greyish cast glass.....Silesian/Bohemian, and a fine, and unusual footed and engraved example. Trying to figure out the heraldry engraving......Eastern European. Extremely fine and guaranteed about 350 years old. Has a geometric cut foot....a chip too, as photographed. A couple teeny flecks to cut top rim. A very nice, interesting, quality example. About 3 5/8" tall and 2 5/8" diameter. Polished pontil. No cracks, no repairs.
