(I'd like this to go in the Stove forum, but am afraid this may not be relevant enough). Just returned from Barcelona, where I visited Casa Mila, designed by Antoni Gaudi and built in 1906-1912. The attached photos were taken in an apartment restored with period furnishings and equipment. One is of a small stove (coal, I assume), used by the staff for heating flatirons. The other is a cookstove in the kitchen. I can't tell whether they had gas then, or still used wood or coal. There was an elevator in the building, so I assume they probably had gas as well. Enjoy...and if you ever get to Barcelona, Casa Mila is spectacular!
