That made the tool more convenient than having to constantly return the iron to the fire.
However, it was still much more complicated to use than a modern electric iron.
The user had to manage the fuel, heat, smoke, and temperature.
There was no convenient dial.
There was no automatic shutoff.
There was no electrical cord.
And there certainly wasn’t a digital display telling you the exact temperature.
The person doing the ironing had to rely on experience.
How Did It Work?
The basic principle was surprisingly simple.
First, charcoal was heated until it was hot enough to produce substantial heat.
The hot charcoal was then placed inside the iron’s chamber.
The lid was closed, helping contain the fuel while allowing the necessary airflow.
As the charcoal burned or smoldered, it heated the surrounding metal.
Eventually, the bottom of the iron became hot.
The user could then place it against clothing and move it across the fabric.
