The pieces were made in three parts--bowl, stem, and foot--the stem being sometimes plain, oftener air-twisted, and sometimes opaque-twisted. The straight-sided bowl was never popular amongst Continental glass-workers, so that the probability is that any specimen found is of English manufacture. In examples of foreign manufacture, too, the bowl was generally rounded at the base, and the stems were often coloured or opaque-twisted. Other characteristics by which these may be identified are their comparative lightness of weight, their fragility, their coarse lavishness of decoration, their narrow bases, while the twisting of the stems is often unduly close, and the bowls have wide, flat flutes. _Ogee Glasses._--The straight-sided glasses changed by easy degrees into the well-known ogee shape, the lines of the bowl being gradually merged into those of the stem. It may be safely asserted that the majority of ogee-shaped glasses are of English manufacture. The majority have opaque-twisted stems; sometimes blue lines replace the opaque white. It is thought that Bristol was the chief place of manufacture, since most of the finds have been in the west of England. The earliest of them have unfolded feet, inserted air-twisted stems, and naturally, since the object of the designer was to preserve the ogee line, no shoulders. Many of them are of considerable dimensions--a possible result of the custom of drinking bumpers. A great number of the memorial glasses, treated of in a separate chapter, were of this type. The [Illustration: FIG. 10.--DOUBLE OGEE BOWLS. (From the Rees Price Collection, by permission of the Connoisseur.)] scheme of decoration followed much the same lines as that of the straight-sided glasses, but a greater proportion were plain; possibly the curves toward the bottom of the bowl made the engraver’s task more difficult. In the later specimens, sprigs of laurel and festoons of various conventional types are to be found. In the Bristol glasses the bowls were sometimes fluted, and a double ogee curve was employed, the upper part only being decorated, generally with vine leaves and bunches of grapes. The stems were bulbed or knopped, and the feet were folded.
