He visited Newcastle-on-Tyne in August 1815 and arranged for samples of the explosive gas firedamp to be sent to him at the Royal Institution. He confirmed that methane was the main constituent and independently confirmed the observations of Tennant and Wollaston that this gas could be ignited only at a high temperature. Because of this it will not communicate flame through a narrow tube of sufficient length; the cooling effect of the tube is too great. Davy contructed lamps in which the air intake and the chimney were composed of narrow tubes, and found that they did not explode firedamp. He then found that wire gauze was equally efficient; and the Davy lamp, in which the flame is surrounded by wire gauze, was born.The whole research occupied less than three months, and is an example of Davy at his best. It led to research on flame, in which he concluded that luminosity is due to the presence of solid particles" (DSB). - Die Tafeln stärker wasserrandig.
