What is the difference between ceramic, terracotta and zellige tiles?

Ceramic tiles are made from clay and other mineral materials that are shaped and fired at high temperatures. Their properties vary depending on the composition, firing process and surface treatment. Terracotta is a clay-based ceramic material traditionally associated with warm, earthy tones and a distinctive natural texture. It may be left unglazed or finished with a glaze. Zellige is a traditional Moroccan glazed clay tile, known for its hand-cut edges, irregular surfaces and subtle differences in colour and reflection. Each material creates a different architectural expression and requires installation and care appropriate to its properties.
