The industrial production of aluminum was made possible by the invention of the electrolytic aluminum process in 1886. Aluminum had been discovered in 1825 and due to the difficulty of converting bauxite to the metal was basically considered to be a precious metal till the Hall–Héroult process came on line in the 1890s. This ad is from 1911, letting everyone know it was here to stay. Interesting that all the products are directed at the woman of the house. That would soon change with the metal becoming an integral part of the aviation industry during World War 1.
