Portuguese tiles, also known as azulejos, are very different from tiles made in Spain or Morocco in terms of their design, history, and production techniques.

Design:

Portuguese tiles are often characterized by their intricate and detailed blue and white or multi-colored patterns, which typically feature geometric or floral designs. Spanish tiles, on the other hand, often incorporate more vivid and bold colors, such as yellow, green, and red, and may feature patterns inspired by Islamic art. Moroccan tiles are known for their vibrant colors and often incorporate intricate geometric patterns and calligraphy.

History: The use of tiles in Portugal dates back to the 13th century when the Arabs introduced glazed ceramics to the country. Over time, Portuguese tile design became heavily influenced by the Renaissance, Baroque, and Rococo styles. In Spain, the use of decorative tiles can be traced back to the 10th century when Islamic art and architecture flourished in the region. Moroccan tiles have a long history as well, with some of the oldest surviving examples dating back to the 13th century.

Production techniques:

Portuguese tiles are typically made using a tin-glazed ceramic technique known as majolica, which involves applying a white glaze to the tile and then painting the design on top. Spanish tiles are often made using a similar technique, but may also incorporate other methods such as cuerda seca, which involves using a wax resist to create raised lines between glazes. Moroccan tiles are often made using zellij, which involves cutting geometric shapes from clay tiles and fitting them together like a puzzle.

While all three styles of tiles share similarities in their use of glazes and patterns, Portuguese tiles are distinct in their intricate blue and white designs and use of the majolica technique, while Spanish and Moroccan tiles often incorporate different colors and patterns inspired by Islamic art.
