Rare Square Sided Apothecary Phial Vial

Square sided phial in aqua glass. The bottle has been buried all of its life and has a wonderful iridescence to the glass. Rough pontil to base. Unfortunately there is a crack on one panel but it is stable. This form is very hard to find and still worthy of adding to any collection. Height 3 inches, width 2 inches. Late 17th century. Dutch or German
