The Edwardian home runs on brand-new technology that nobody has learned to fear yet. Historian Suzannah Lipscomb walks through the period between 1901 and 1914, an age of firsts, mass-produced cars, powered flight, electricity spreading into ordinary houses, and shows how each innovation arrived with a hidden cost. Early refrigerators leak flammable, toxic gas into kitchens. Asbestos, newly used in factories, rides home on workers' clothes and into the laundry their families handle by hand. Cosmetics sold to women chasing the fashionable look cause hair loss and corneal damage, and radium, prized simply for glowing in the dark, ends up in socks, toothpaste, chocolate, and drinking water. Lipscomb talks with historians who trace each hazard back to the specific product and the specific ignorance behind it, whether that's a badly sealed appliance or a dye nobody tested. The pattern she keeps returning to is convenience outrunning understanding, and the closing implication is that today's households are running the same experiment with different materials.
