Collateral advantages of no small importance have resulted from these inventions; insomuch as they have tended very considerably to enhance the value of British Glass-wares, and to extend the application of Glass to new purposes of domestic utility. The highly ornamental effect which by this and other improvements has been given to the manufacture, has recommended Glass incrustations and other ornamental Glass, in the place of metal ornaments, for door-plates or handles, lamp pedestals, arms, &c., upon decanters, chandeliers, and articles of table Glass.

A third patent has been completed for casting from common bottle-glass metal, water or gas-pipes; but it has not yet practically worked out those results which will, no doubt, be attained by more extended experiments and arrangements.

Sky-lights are moulded in strong flint Glass, of embossed patterns to the segment of a dome, or sphere;* and strong panes for windows, or sky-lights, are ornamented with detached pieces of transparent coloured Glass, massed homogeneously to white Glass, and having together, a Mosaic and ornamental appearance; these being included in the last mentioned patent.

England is pre-eminent for her refractive, colourless, flint Glass for chandeliers and table articles; and the transparent metallic colours are of superior quality. With such materials, when artistic education becomes more extended, the English Glass-makers will, it is hoped, rival their Continental competitors, in colouring, gilding, and elegant forms.
