[edit] Ultraviolet

Chance Brothers were responsible for perfecting the earliest optical lenses to block the harmful ultra violet rays of the sun.^{[citation needed]}

This looks like a garbling of this. The innovation wasn't to block UV, but a formula to make UV-transparent glass stay that way. Gordonofcartoon 03:19, 31 July 2007 (UTC)

No, it could also refer to the development of Crookes lenses (see Sir William Crookes: http://en.wikipedia.org/wiki/William_Crookes), that were used to block UV light (arc welding, sunglasses, etc.) Chance were still using 'Crookes' as a tradename into the 1960s.

Thx. Anyway, it needs a check, as you've commented below. Another one is "the innovative welding of a cathode ray tube used for radar detection". It's not clear, even from the online source [1] , what was innovative. The tube itself? Making it by welding? Welding something to it? Gordonofcartoon 13:42, 1 August 2007 (UTC)

Take over by Pilkington in 1951. A contentious issue - Pilkington acquired 50% of Chance stock in 1945, but didn't fully take over Chance Brothers until late 1952. Depends on the definition of 'take over', but personally I prefer to use the latter date. GlassyEye 21:15, 31 July 2007 (UTC)

...they also were the only firm at the time able to make the white glass for the four faces of Big Ben. It isn't called "Big Ben" - that refers to the large bell. The proper name is the Clock Tower, Palace of Westminster (http://en.wikipedia.org/wiki/Clock_Tower,_Palace_of_Westminster). Chance were the only UK firm able to replace the glass - Chance actually replaced the German glass after the war that had, ironically, been damaged by the Luftwaffe! Due to the differences in colour, it was decided to replace all the glass. This glass is referred to as opal-flashed - a thin layer of opal glass that is 'flashed' onto the outer faces of clear glass. GlassyEye 21:23, 31 July 2007 (UTC)
