It is because the wire absorbs or takes a way the heat of all flame that approaches or comes between them when the flame is divided by a gauze of the above texture but which would not be the case were the distances between the wire greater than specified, owing to the quality of the flame which would be less divided overcoming the power of the wire to conduct away the heat, consequently the flame or blaze would pass through the gauze and explode the gas outside the lamp. Also be gentle with pouring oil. They have typical kind of substances that would instantly react with water (if mixed) and create carbon dioxide as a result of chemical reaction.

That is the reason why it couldn’t mix with water. Created in 1815, it was designed to be lit safely for miners to use without allowing the heat from the flame to explode the concentration of methane gas often found as miners dug deeper. This is where all the action is going to happen, so it is important to have enough oil to show the blobs clearly. Water is heavier than oil. The wire mesh used in the lamps was prone to rust and breakage, permitting an explosion, so the lamps tended to create a false sense of security.
