In addition to the materials used, the design of high temperature shaft seals is also crucial for their performance. The seal must effectively block the passage of fluids or gases through the interface between the moving shaft and stationary housing. This requires precise engineering to ensure a tight fit and proper sealing under varying temperature and pressure conditions.

The production of terracotta roof tiles was a skilled craft. Romans developed sophisticated methods for shaping and firing the clay. They often used local clay, which varied in color and texture, resulting in tiles with distinct appearances. The firing process involved high temperatures, which caused the clay to harden and develop a rich, reddish hue, a characteristic feature of many Roman structures. This not only imparted strength but also added an aesthetic quality that integrated beautifully with the surrounding environment.
