THE FIRST ENGLISH GLASS-HOUSES.
for them to evince their superiority in the ornamental branches of the art; and this has been partially accomplished by the improved taste of the public, compelling manufacturers to employ superior artists; as well as by the encouragement given by Government in establishing Schools of Design for instruction in classic design and correct drawing.
The ancients were not altogether ignorant of the art of embodying ornament in the interior of Glass; but their productions were only partially enclosed. The picture of a duck, described by Winckelmann, or the arabesque Mosaic in the British Museum, is but a partial incrustation; as the painting is neither completely enclosed, nor protected from the air. The Venetian ball and the Bohemian ornamental stems are perfect encrustations; but they are curious, rather than tastefully designed, or useful. It was impossible to introduce into the interior of Glass any device or figure, which could be with certainty accurately defined; because, the variegated Glass in the interior being of the same nature as the enamel, is (especially if opaque) fusible at a less degree of heat than the coating of white transparent glass; consequently, any impression must have been effaced, when, in the process of manufacture, it became incased in the hot transparent Glass. To render the art of incrustation subservient to any useful purpose, it was requisite, in the first instance, to discover a substance capable of uniting with Glass, but requiring a stronger heat than its transparent enclosure to render it fusible.
About forty years since, a Bohemian manufacturer first attempted to incrust in Glass, small figures of greyish clay. The experiments which he made, were in but few instances successful, in consequence of the clay not being adapted to
