3. THE CORRUGATED ROUND STEM
(1) CORRUGATED STEM AND (2) HOP AND BARLEY GLASSES, THE LATTER SHOWING THE “SILVER SPIRAL”
Stems which are ornamented by outside spirals, or series of small ridges and grooves alternating, are usually old Dutch; but some of them are English, though of inferior quality and ring. The quality is so poor and the make so unsatisfactory that probably they were a “cheap and nasty” contemporary imitation and substitute for glasses adorned with the air spiral, the type which succeed the plain round stem. It is hardly likely that the corrugated stem preceded the air-spiral stem; or, if at all, for more than a few years. With these corrugated stems one expects to find, almost without exception, that the bowl of the glass is shaped like an inverted, incurving, waisted bell.
