Intaglio — decorative technique where a design is stamped or incised into the surface of a tile, creating a relief pattern in reverse. Instead of the design protruding outwards, it is recessed or sunken into the tile's surface.

To achieve an intaglio design, a stamp or tool with the desired pattern or image is pressed into the soft clay or material used for the tile. The pressure of the stamp leaves an impression, creating the recessed design. This technique allows for precise and intricate details to be captured in the tile's surface.

Once the intaglio design is imprinted, the tile is typically fired in a kiln to harden and set the clay or material. The firing process solidifies the tile, preserving the relief pattern.

Intaglio designs can be found in various forms of tiling, including ceramic tiles, terracotta tiles, and even stone tiles. They are often used to add texture, visual interest, and artistic expression to architectural surfaces, walls, and floors.

The beauty of intaglio lies in its ability to create depth and shadow through the recessed areas, giving the design a three-dimensional appearance. It has been a popular technique in artistic and architectural traditions throughout history, showcasing the skill and craftsmanship of tile makers and adding a touch of elegance and sophistication to interior and exterior spaces.
