Vintage coal-heated irons, also known as box irons or charcoal irons, were heavy cast-iron containers with hollow chambers where hot coals or charcoal were placed for heat, featuring wooden handles for insulation and vents for air, serving as essential tools for crisp clothes before electricity, known for their robust build, manual heat management, and rustic charm, making them popular collectibles and props.

Key Features:

Construction: Heavy cast iron body, often with ornate details, riveted or seamless construction, and a secure hinged lid.

Fuel Source: Burning wood charcoal or hot coals placed inside the cavity.

Handle: A thick, insulated wooden handle to protect users from the intense heat.

Vents: Air vents or chimneys on the sides to provide oxygen, keeping the fire burning.

Function: Heated from within, they provided sustained, intense heat for ironing, requiring careful handling and temperature checks (often by spraying water or testing on a cloth).

Historical Significance:
