Notes: 1. Use of a circular Argand burner was not reserved to the assorted free-standing lamps which were found in well-to-do homes of the first half of the 19th century. That technology had also been adapted for use with the coal-gas burning gasoliers of the period because a circular burner helped to eliminate problems of maintaining steady pressure in the infant gas light industry Descendants of the circular burner are still found in the modern gas stove. |
