Glass Fire Grenades were decorative glass bottles designed to put out fires in the nineteenth century. The London Fire Brigade Museum has a collection of 21 examples, with the earliest ones dating back to c.1880. These grenades were filled with salt water or carbon tetrachloride, the latter of which had potentially dangerous health effects. Despite their shortcomings, the grenades were in use for about forty years and even allegedly used by the Royal family. The London Fire Brigade Museum plans to showcase these forgotten objects in their new museum, aiming to educate visitors about fire safety.
