Abstract: Porcelain stoneware tiles were used as cladding for reinforced concrete frames when they were introduced into urban architecture in the early twentieth century in Paris. The fortuitous encounter of the two materials is illustrated by the profusion of treatises, manuals, and guides devoted to industrial ceramics and reinforced concrete between 1890 and 1910. A study of the technical literature illustrates the material conditions for the use of porcelain stoneware for the cladding of these buildings.
