Given the DYK hook and a coupleof mentions of this cold flame in the article, I was disappointed to find no hint of the temperature of said flame in the article. --Tagishsimon(talk)01:48, 8 February 2012 (UTC)[reply]
According to the cool flame article, "The lowest temperature of a cool flame is poorly defined and is conventionally set as temperature at which the flame can be detected by eye in a dark room". I interpret this to mean that it may be difficult to measure since it may be difficult to see. Daniel Case (talk) 05:36, 8 February 2012 (UTC)[reply]
Actually, I found the cited article, specifically the page where they discuss the flame temperature, here. One thing the discoverers repeat over and over is the extreme instability of the gas. I suspect it didn't last long enough for them to have any sufficient quantity to measure the flame temperature, and they may have been preoccupied with trying to make more essential observations.

I found nothing on measuring the temperature with a thermometer so far so no °C. PF3 one of the burn products is not safe at all, (reacts with hemoglobin) so I don't recommend trying this at home. Graeme Bartlett (talk) 09:07, 8 February 2012 (UTC)[reply]
