14. Bone tube or nozzle, possibly part of a syringe. Internal bore spreads from 1/8 in. at the narrow, broken end, to 3/8 in. at the other end. The increase in bore begins at a point 3/4 in. from the wide end. The latter terminates on the exterior in a collar above six encircling grooves, below which the tube is trumpet-shaped and ornamented with two shallow incised rings. T.N. 17. 15. Bone tube of uncertain purpose. Trimmed at the narrow end to fit within a collar or extension; the wider end spreading and convex, the interior of this end with spiral groove to create threading to house a screw-ended plug or extension. T.N. 17. 16. Wineglass stem. Heavy and solid inverted baluster with small fortuitous tear; the lead metal a smoky gray with an almost frosted appearance resulting from surface decay.[149] The bowl, though large, was comparatively thin at its junction with the stem and probably, therefore, was of funnel form. Late 17th century. T.N. 22. 17. Light wineglass. Pale straw-colored metal;[150] inverted baluster stem is hollow and gently tooled into quatrefoil form at its junction with the bowl,[151] the latter setting firmly into the top of the stem. The conical foot with central pontil mark is thin and was undoubtedly folded. This is an important 3-piece glass of a type sometimes attributed to Hawley Bishop, George Ravenscroft's successor at the Henley-on-Thames glasshouse.[152] About 1680-1700. T.N. 30. 18. Wineglass stem. Sparkling lead metal; the stem comprising a solid, inverted baluster beneath a massive cushion knop, the base of the bowl nestling firmly within the latter. Late 17th century to early 18th century.[153] T.N. 4. FIGURE 18 ENGLISH DELFTWARE 1. Bowl with everted rim ornamented with crudely overlapping ovals and diamonds in blue; interior of bowl decorated with rings of the same color. The conjectural base and foot are derived from larger bowls of similar form found in excavations at Williamsburg. The glaze is thick, and very white. Late 17th century to early 18th century. T.N. 30. 2. Rim sherd from bowl of form similar to the above, but the blue decoration on the interior of the bowl and the rim plain. T.N. 23.
