Sauce bottle

The bottle is complete, except for a chip on the neck. It is rectangular with chamfered corners. In cross-section, it has a straight wall, a rounded shoulder and a high neck tapering upwards, ending in a neck with a straight, uneven annular ring, below a frustoconical lip with an uneven, fire-polished top. The base is straight and slightly recessed, and the bottom has a wide fulcrum; the center is sunken into a dome, and shows a trace of sand pontil. There are two mold lines from the underside of the base to the neck at mid-height ; none other than the shape of the object and the green color of the glass.
