How Water Causes a Fire

1901

One would hardly believe that a bottle of water standing harmlessly on a table could be the cause of a fire. Nevertheless such is the case.

In my laboratory the other day I detected the odor of burning wood and, seeking the cause, noticed a tiny wreath of smoke rising from the counter. Setting aside a flask of water that stood close by I sponged over the burning spot with a damp cloth. Shortly after I again detected the odor of burning wood, when, to my surprise, I discovered another burning spot on the table close to the water flask. The flask was standing in the sunlight, thereby concentrating the rays to a focus on the top of the table, acting in this case as a burning glass. A handful of highly combustible material was thrown over the burning spot, catching fire almost immediately.

I cite this instance merely as a warning to chemists and apothecaries, who may not realize how easily a fire may be started in their storerooms by the sun shining through bottles, flasks and carboys of liquid, converting them for the time being into burning glasses of great power. I have in mind now the instance of a fire originating in a storeroom from this cause. — New York Times.
