Fireplace cooking was hard work. Frequent bending and stooping were necessary, and cast iron cookware was heavy. It was also dangerous work. Most long skirts had a burned place at the bottom, and hot coals popped onto wooden floors daily.
Metal stoves were adopted quicker than any invention before radio and television. A stove was also more efficient than a fireplace; it saved a lot of wood cutting. Throw a small pinch of flour into the oven of a wood stove. If it is just starting to brown after 30 sec, the temperature is right for baking bread and cakes.
