William Burton and Henry Beauchamp Walters, 1911 Encyclopædia Britannica (1911)
“ For this default the manufacturer is not so much to blame as are those modern architects who design a building for stone construction and then decide to have it executed in terracotta. The shrinkage of clay both in drying and firing is well known, and it is this shrinkage which causes large pieces of terracotta to twist or become crooked. When our modern architects shall have realized that the details of a building must be designed specially for the material that is to be used in its construction, terracotta will come into its own again as a decorative building material. ”
