Ah i see. I must admit i know very little about the art of glass production, but looking at how Pilkington do it, they lay it out flat on a tray of molten tin i think they were saying, and they also said this method they invented is adopted by the industry now. Perhaps toughened glass needs a different process. Toughened glass is made by a repeated heating and cooling process. Yes that makes sense. Presumably that is to remove the dislocations in it. Surface coatings also affect the strength as seen in the video I posted. |

I have been to Pilkington glass works quite a few times. They don't lay the glass flat tray - it is a continuous flow. Variable speed drives control the flow. In the event that the drives fail there is a huge battery back up. Well that's what they said in some PR video. They said they patented the process and it was subsequently the industry standard method. The reasoning is the surface is perfectly flat due to gravity. It may well have been a continuous process where I guess it has cooled sufficiently it is then chopped into pieces. I only caught a glimpse of the factory and this factory was probably in the US. There is no "may well have been" about it. It IS continuous. |

Fairy 'nuff. Just to give you an idea of the scale of things the Plkington rig was close to 100 metres end to end. A bit similar to a paper machine. Do you like my dog ? |
