The following is another illustration of the process of making by hand. For many years, the trade in French Lamp-shades, or semi-circles, has formed a large proportion of employment for the castor-hole chair. The fitting part of the shade is usually about ten inches, and the swell of its vase-like form, about twelve inches, diameter: these are too large to be made at other chairs, as they warm at the mouths of pots holding metal, the openings of which seldom admit of articles exceeding six or eight inches. The mouth of the castor-hole pot is about twenty-four inches, which is diminished at pleasure, by rolls of Stourbridge clay, diminishing, circle upon circle, until the required size of the opening is attained. The French enlarge or lessen the opening of the castor-pot by consecutive rings of burnt clay, fitting upon each other, a much superior and cleaner mode of effecting the same object. A few years since, this plan was tried in our own Glassworks, but was soon discontinued.

The footmaker takes a solid lump of Glass, A, which, after a second gathering, will weight about four pounds, B. The blowing-iron is stronger, thicker, and of a larger bore, than those used by the other chairs; and the blower, by adroitly rubbing it on the marver, and blowing simultaneously with the rotating motion, approximates it somewhat towards its ultimate form, C. The knob at D is
