The basis of almost all flame-safety lamps can be linked back to Davy’s discovery of gauze, as a way to seperate gas from the flame. However, the Best Gauzeless lamp returned to the work of Stephenson, by instead using perforated metal plates. Where gauze was used in other lamps, metal cylinders with numerous fine holes were employed instead. Replacing the gauze with plates meant the lamp was potentially easier to clean and maintain and potentially more robust.
