Classification description:

Manufacture or treatment of flakes, fibres, or filaments from softened glass, minerals, or slags; Manufacture of glass fibres or filaments; Manufacture of preforms for drawing fibres or filaments made entirely or partially by chemical means, e.g. vapour phase deposition of bulk porous glass either by outside vapour deposition [OVD], or by outside vapour phase oxidation [OVPO] or by vapour axial deposition [VAD]; Means for supporting, rotating or translating the preforms being formed, e.g. lathes Deposition substrates, e.g. targets, mandrels, start rods or tubes
