Many of these glasses are still in existence and it is even possible for the amateur collector to acquire an occasional specimen. This early eighteenth-century glass is of remarkable quality, both as regards form and lustre. It is true that it is less perfect in shape and texture than the products of to-day, but it is superior in artistic merit, in originality of design and softness of outline. The lack of perfect symmetry is one of its charms, as it is in the case of old lace which, so far as absolute and meticulous perfection of detail is concerned, is often far behind the modern machine-made product. But what it lacks in symmetry and precision is more than compensated by artistic feeling.

Mr Hartshorne in his monumental work on “Old English Glasses,” a work to which the present writer and every other writer on the subject must acknowledge a vast indebtedness, makes an exhaustive classification of the various types of eighteenth-century glasses. To his order one is bound closely to conform, although it is far from the province of the present work to attempt to deal exhaustively with the various types he so fully and admirably describes.

The earliest examples have funnel-shaped bowls with tall stems. These are of great variety of shape. Some are quite plain, others are twisted, others ribbed. Some, again, are “baluster” shaped, i.e. formed after the pattern of the columns of a balustrade. Many have a knop or button in the middle, others are ornamented with twisted lines, either hollow or filled with glass of different colours, interwoven in spirals, twists, networks and plaits in all kinds of ingenious ways.

Of course, all these things being distinctive are imitable, and here the peril of the collector begins. The expert is rarely deceived as to whether any specimen is genuine old glass; but so pervasive and so perfect are the imitations that exist, and so plausible the conditions under which they are found, that it behoves the amateur to use the extremest caution. I propose to deal at some length with some of the more obvious and frequent frauds and fakes in a subsequent chapter. But for the moment it may be said that the best test of genuineness is neither shape nor any particular design—for these can be closely imitated—but the colour. There is a curious tint in old glass which the new never quite achieves. The would-be small collector will be well advised if, before riding his hobby, he goes through a brief course of eye-training under the guidance of an expert, until he gets the exact tone of the old glass firmly impressed upon his memory. As an additional factor, it should always be borne in mind that the old glass is invariably heavier than its modern imitation.

It will be desirable at this point to describe in brief detail the more important of the types of eighteenth-century glass enumerated on page 59.
