Speciality Processing of Glass Ends
| Cracked off or cut The cut or cracked off surface has a rough texture and sharp edges. Intended mainly for further processing or where the end finish is unimportant. | |
| Ends fire polished The ends are fire polished after cracking off or cutting, leaving a very smooth round edge proving protection from splintering of the edges. Fire polishing also reseals the surface of the glass edge weakened during the cutting process. | |
| Ground, chamfered inside and outside, also available fire polished Smooth surfaces and edges. The smoothed area on the inside and outside gives protection against chipping and damage to equipment used in assembly with the glass tube. | |
| Ground square and parallel Both ends of the tube are ground square and parallel to meet exacting standards. | |
| Special end finishes The tube ends are chamfered externally and/or internally according to customer specifications. | |
| External step Steps are ground externally at the tube ends according to customer specifications. This permits exact centring when installing the tubes or the fitting of external devices. | |
| Defined constriction or flare at the ends The tube ends are constricted or flared according to customer specifications to restrict the flow or ease the entry into the glass tube. |
