DescriptionTransparent to translucent dusky yellow (near 5 Y 6/4). Medium thin glass. Blown into a four-part mold with three vertical sections joined to a disk-shaped base section (MCT III). Relief crisp. Rim slightly ground with slight bulge below. Truncated conical body. Flat base with two raised concentric rings and central boss. A faint wheel-cut incision on exterior ca. 0.9 cm below rim. On body, six alternating rows of eight knot-shaped knobs in three-tiered relief diminishing toward base. Just above junction with base is a horizontal ridge; it is not a mold seam, since the vertical seams extend through this line to edge of base. A few small bubbles.
