Who else has a copper fire extinguisher?
Mine is a “Success” by John’s Mannvile
They run on sodium bicarbonate solution and a small cup of sulfuric acid at the top. When turned over the acid mixes into the sodium bicarbonate generating gas pressure to force the water out the hose.
To me, these copper extinguishers display high levels of skill in:
Design
Metallurgy
Chemistry and
Manufacturing.
They also show off the art inherent in function driving form
