Not quite the same place as when I used to visit on business. However, as posted previously, Chance Glass Ltd are still going strong in Malvern, and I supplied them with high temperature-resistant materials for handling hot glass. There is still a market for precision Pyrex tubes and optically-pure components such as medical slides.
One of Chance's major markets was for TV tubes, and a couple of managers set up their own company making the rear connectors for tubes, also in Oldbury. I can't remember the name of this company, even though I supplied them (!), but they no longer exist as cathode-ray tube TV's are a thing of the past. I always liked working in and with the glass industry, and my first 'proper' job was as a technologist at Triplex Safety Glass Co, Kings Norton.
