Introduction to Antique Glass Fire Extinguishers
Long before modern fire suppression systems, glass fire extinguishers represented ingenious early attempts at fire safety. These distinctive glass devices, often referred to as “fire grenades,” were popular from the late 19th century through the early 20th century. Today, they’ve become sought-after collectibles that combine historical significance with decorative appeal.
These vintage fire safety devices came in various forms - from wall-mounted units with glass bulbs to handheld glass grenades designed to be thrown at flames. Their distinctive shapes, vibrant colors, and historical significance have made them increasingly valuable to collectors of firefighting memorabilia, antique glass, and historical artifacts.
In this comprehensive guide, we’ll explore what determines the value of these fascinating pieces of firefighting history, how to identify different types, current market prices, and important considerations for collectors.

<span>Types of Antique Glass Fire Extinguishers</span>
</h2>
<div class="section-header__body">Various designs of glass fire extinguishers were manufactured from the 1870s through the early 1900s, each with distinct characteristics that affect their collectible value.</div>
Fire Grenades
The most common type of glass fire extinguisher was the “fire grenade” - a handheld glass bulb filled with fire-suppressing chemicals. These were designed to be thrown at fires, with the glass breaking on impact and releasing the extinguishing agent.
Popular manufacturers included:
Harden’s Hand Fire Extinguisher
Hayward Hand Grenade Fire Extinguisher
Red Comet Fire Grenades
Little Giant Fire Extinguisher
Wall-Mounted Automatic Units
More sophisticated systems featured wall-mounted brackets holding large glass bulbs designed to automatically break and release their contents when temperatures reached a certain point.
Notable manufacturers included:
AutoFyrStop
Star Automatic Fire Extinguisher
Guardian Fire Extinguisher
Nutting Automatic Fire Extinguisher
These units typically featured a mounting bracket, decorative metal cage, and a glass bulb that would shatter when exposed to heat.
Chemical Compositions
Most glass fire extinguishers contained one of these chemicals:
Carbon tetrachloride (most common)
Salt water solutions
Sodium bicarbonate mixtures
Calcium chloride solutions
Safety note: Many antique fire extinguishers contain chemicals now known to be hazardous. Carbon tetrachloride, in particular, is now recognized as toxic and potentially carcinogenic. Collections should be handled with care, and broken specimens should be treated as hazardous materials.

<span>Factors Affecting Value</span>
</h2>
<div class="section-header__body">Several key factors determine the collectible value of antique glass fire extinguishers in today’s market.</div>
Rarity and Age
The age and scarcity of a fire grenade significantly impacts its value. Earlier examples from the 1870s-1890s typically command higher prices than later models. Limited production runs or extinguishers from smaller manufacturers tend to be more valuable due to their scarcity.
Condition
Condition is perhaps the most critical factor in valuation:
Condition Assessment for Glass Fire Extinguishers
Check applicable items to determine overall condition
Complete glass integrity with no cracks or chips
Original liquid contents still present and sealed
Clear, legible embossed manufacturer markings
Original mounting hardware or brackets included
Original paint or finish in good condition
Matching set or complete system intact
Color and Decorative Elements
Glass fire extinguishers came in various colors, with some being significantly more desirable to collectors:
Blue: Among the most sought-after, particularly cobalt blue examples
Amber/Brown: Common but still collectible
Clear: Most common, typically less valuable unless rare design
Green: Relatively uncommon and desirable
Red/Ruby: Rare and highly prized by collectors
Purple/Amethyst: Extremely rare and valuable
Extinguishers with decorative embossing, etched patterns, or colorful painted labels add significantly to their value.
Manufacturer and Provenance
Certain manufacturers are known for higher quality or more decorative designs. Additionally, documented provenance from historic buildings, notable locations, or famous owners can substantially increase value.
Completeness
Complete systems with original mounting brackets, wall fixtures, or display elements are worth considerably more than the glass components alone. For example, a complete AutoFyrStop system with the original ceiling mount and decorative cage can be worth 3-5 times more than just the glass bulb.

Common Questions About Glass Fire Extinguisher Values
Is there any value in old fire extinguishers?
Yes, antique glass fire extinguishers can be quite valuable collectibles. Their value ranges from $25 for common, damaged specimens to over $2,000 for rare, museum-quality examples. The most desirable are complete units in unusual colors (like cobalt blue or ruby red) with their original mounting hardware and in excellent condition.
These items are valued for their historical significance, decorative appeal, and connection to early firefighting history. Many collectors appreciate them for their ornate Victorian designs and beautiful colored glass.
What's in old glass fire extinguishers?
Most antique glass fire extinguishers contained carbon tetrachloride, a chemical that was effective at suppressing flames but is now known to be toxic and potentially carcinogenic. Some contained salt water solutions, sodium bicarbonate mixtures, or calcium chloride solutions.
Because of the potentially hazardous contents, collectors should handle these items with care and consider displaying empty specimens. Never break or open sealed extinguishers, and consult hazardous waste facilities if you need to dispose of the contents.
How can I tell how old my glass fire extinguisher is?
You can determine the approximate age of a glass fire extinguisher by:
Looking for patent dates embossed on the glass (common from 1880-1910)
Examining the manufacturing techniques (hand-blown with irregular bubbles indicates earlier production)
Checking the color (earlier pieces often have deeper, more vibrant colors)
Researching the manufacturer marks against known production dates
Noting the shape and design (designs evolved over time)
Most collectible glass fire extinguishers date from the 1870s through the early 1920s, with the majority produced between 1880-1900.
Are glass fire extinguishers safe to keep in my home?
Glass fire extinguishers containing their original chemicals should be handled with caution. The carbon tetrachloride in many vintage extinguishers is now recognized as toxic and potentially carcinogenic. For safety:
Consider displaying empty specimens
Store in cool, stable locations away from heat sources
Keep in sealed display cases if they contain original fluid
Keep away from children and pets
Handle with gloves to avoid contact with potential residues
Never use an antique fire extinguisher to fight a fire - they’re collectibles, not functional safety equipment.
Who buys old fire extinguishers?
Several groups actively purchase antique glass fire extinguishers:
Collectors of firefighting memorabilia and equipment
Antique glass collectors (particularly for colored glass examples)
Interior designers using them as decorative pieces
Museums and historical societies (for significant examples)
Prop masters and set designers for period films and productions
Restoration specialists working on historic buildings
The best markets are usually specialty online forums, collector groups, antique shows, and auction houses that specialize in industrial antiques or firefighting memorabilia.
What were fire grenades used for?
Fire grenades were an early form of fire extinguisher popular from the 1870s through the early 1900s. They were glass bulbs filled with fire-suppressing chemicals, typically carbon tetrachloride, designed to be thrown into fires.
The concept was simple: when thrown at a fire, the glass would break on impact, releasing the chemical that would smother the flames by displacing oxygen and interrupting the combustion process. Some versions were designed to be mounted on walls or ceilings where they would automatically break when exposed to high heat, providing an early automatic fire suppression system.
These devices were commonly found in homes, businesses, theaters, and public buildings before more effective fire extinguisher technologies were developed.
