Harden's Hand Grenade Fire Extinguisher Value Guide

Patented in 1883 by Henry Harden, these blue quilted glass spheres represent a unique era of Victorian fire safety innovation. They are highly collectible today for their distinct aesthetic and their historical role as early chemical fire suppression tools used in 19th-century homes.

What affects the value of Harden's Hand Grenade Fire Extinguisher?

• The presence of the original liquid contents can increase rarity but poses significant health risks due to chemical toxicity.
• Glass condition is paramount; chips, cracks, or heavy clouding significantly reduce the $250-$300 market value.
• The clarity and depth of the embossed lettering and the sharpness of the quilted pattern affect desirability.
• Authentic original labels or mounting brackets can command a premium price from specialized fire memorabilia collectors.

How to Identify Harden's Hand Grenade Fire Extinguisher?

• Look for the distinct 'quilted' or diamond-patterned texture molded into the cobalt blue glass surface.
• Verify the embossed text which typically includes 'Harden's Hand Grenade' and the 1883 patent date.
• Check for the original lead seal or cork stopper, though many surviving examples have been emptied of their toxic carbon tetrachloride.
• Examine the glass for a deep, vibrant cobalt blue color characteristic of the 1880-1890 production period.

History of Harden's Hand Grenade Fire Extinguisher

Harden's Hand Grenade Fire Extinguisher was patented in 1883 by Henry Harden. These devices were filled with a carbon tetrachloride solution, which was believed to extinguish flames by smothering them and producing a non-flammable gas. They were popular in homes and businesses before modern fire extinguishers became widespread, offering a seemingly simple solution to small fires. However, carbon tetrachloride is now known to be toxic, and these historical items are valued more for their antique appeal and ingenuity rather than their practical fire-fighting capabilities.
