allowed to cool to a greater degree of hardness than usual; the second coating should be pressed into the mould, A, as hot as possible, that the exterior coating only shall be acted upon by the pressure of moulding, and that the interior shall preserve its smooth circular area. When about half formed, the projecting parts, B, have centrifugal enlargement given to them by a sharp trundling of the iron at, or immediately after, the moment the workman is blowing; during the re-heating process, the piece is separated at C, has a foot welded to it, and is re-warmed, as D; sheared, as E; and when finished, by flashing, shaping, &c., as F, is called patent pillar-moulding. The fire polish is given to it by frequently re-melting the surface of the Glass, after it leaves the mould. A little cutting or scolloping makes this refractive moulding still more ornamental, but, though it much resembles cutting, (as to its round pillars,) it is inferior where sharp angles are required.
