"CRACKLE" GLASS.
An ingenious process of producing glass with an iced or crackled
surface, suitable for many decorative purposes, has been invented in
France by Bay. The product appears in the form of sheets or panes, one
side of which is smooth or glossy, like common window glass, while the
other is rough and filled with innumerable crevices, giving it the
frozen or crackled appearance so much admired for many decorative
purposes. This peculiar cracked surface is obtained by covering
the surface of the sheet on the table with a thick coating of some
coarse-grained flux mixed to form a paste, or with a coating of some
more easily fusible glass, and then subjecting it to the action of a
strong fire, either open or in a muffle. As soon as the coating is
fused, and the table is red-hot, it is withdrawn and rapidly cooled. The
superficial layer of flux separates itself in this operation from
the underlying glass surface, and leaves behind the evidence of its
attachment to the same in the form of numberless irregularities, scales,
irregular crystal forms, etc.
