Flame Heated Soldering Irons

Soldering irons have been around for over 4,000 years.
Up until the 1920s most were heated by open flame.
Torch heated soldering irons were commonly used by
roofers and plumbers into the 1950s.

This is a large flame heated cast iron soldering iron with a copper tip.
The tip is stamped with a Detroit in a diamond, and a #6. The handle has what looks to be a patent date of 12-08-20. It's overall length is 19.5" and it weighs three pounds, four ounces. The copper tip alone is six inches long and over one inch wide. This beast is the largest iron in my collection.

And now for something completely different.
Quick-Shot Thermite Soldering Iron
The "Quick-Shot" Thermite Soldering Iron
That's right "Thermite" (as in Thermite Bomb). It's quite safe if used properly, even though Thermite was used by the Germans in World War II to make bombs for burning cities and used as a trigger in hand grenades, it was also used to weld railroad rails for years, warm baby bottles, and to create heat in these "Quick-Shot" portable soldering irons.

The Quick-Shot soldering iron unscrews behind the copper tip and you insert a "Thermit" cartridge. You then pull out the spring loaded plunger at the end of the handle and let it go (just like launching a ball on a pinball machine). The plunger pierces the cartridge and starts the chemical reaction. It heats in about 20 seconds and each cartridge lasts about eight minutes.

Warning - If a cartridge is broken or pierced outside the iron
it turns white hot and there is a high risk of burns or fire.
DO NOT SHIP CARTRIDGES BY MAIL OR STANDARD CARRIER.

This Quick-Shot model number KS-14582-LI above was manufactured by the Kemode Manufacturing Co. Inc. New York. Original cost with one cartridge was $5.95 in 1948 and around $16.50 by 1956. Cartridges were around $6.00 per dozen.

Clark 1007 Thermite Soldering Iron
This thermite iron's tips look to be interchangeable with the Kemode Quick-Shot iron shown above and the cartridges fit. I could not find any information on a manufacturer and do not know if this thermite powered iron was made for Clark by Kemode Manufacturing Co..
Warning - If a cartridge is broken or pierced outside the iron
it turns white hot and there is a high risk of burns or fire.
DO NOT SHIP CARTRIDGES BY MAIL OR STANDARD CARRIER.
