A1 in ceramic tiles intended for wall tiling.
A1fl in ceramic tiles intended for flooring.
Firing: Heating of the pieces according to an established firing plan and then later cooled following the same plan often called the firing cycle.
Floor Tiles: Compact and opaque ceramic body that becomes tough and non-porous and fires at high temperature (1300°C)
Grout: Material and action to fill the gaps between the tiles. Material must be of the correct type according to the grout width and according to the application of the tile.
Impact resistance: The ability of ceramic tile to resist breakage either throughout the body or as surface chipping- as the result of a heavy blow. In general, ceramic tile is not a resilient material and care should be taken to avoid dropping heavy or sharp objects on its surface
Invisible Clamp: System to anchor ceramic tiles on walls and facades. The clamp that is placed in a cavity made in the tile provides security against detachment
Kaolinite clay: White clay. Very pure, employee as a basic ingredient in the clay of porcelain products.
Lay the floor: Process of laying a ceramic pavement. Place ceramic tiles on a more or less horizontal floor or surface.
Leveler: a system used to fix ceramic floor tiles in order to avoid any deviations in the flatness of the area being tiled.
Leveling system: Fixing system that ensures that there is a flatness between the tiles avoiding any movements during the setting and drying of the mortar.
Loss of Shine and Gloss: Deterioration of the surface of the gloss and shine on the surface of the tile.
Lot: Set of ceramic tiles belonging to the same tone and caliber of manufacture that is identified in the packing and supply sheet.
Mohs: The product resistance against scratches from minerals and dirt is measured by the Mohs Scale to establish its surface toughness
Moisture Expansion: Increased measurement of the ceramic tile exposed to the action of moisture (mm/m).
Open Time: Maximum time indicated by the manufacturer, in which the bonding material retains its properties
Orthogonality: Property of the sides of the ceramic tiles that form a right angle with another side or with another edge.

Primer: The face side of the tile is covered by a mix of white clays to cover the dark colour of the clay
Raw piece: A tile that is unfired. This term is used when the tile is dry and awaiting to be fired for the first time.
Rectangularity: It is said of the right angle between the sides of a ceramic tile. The maximum deviation from rectangularity, in percent, related to the corresponding work sizes
Resistance to Ice: Resistance of the tile to ice without changes in the appearance and/or its internal structure
Resistance to Pedestrian Wear: Classification of the tile according to its capacity to withstand pedestrian traffic on a floor tile
International Standard 13006:2018: Defines terms and establishes classifications, characteristics and marking requirements for ceramic tiles of the best commercial quality (first quality). ISO 13006:2016 is not applicable to tiles made by other than normal processes of extrusion or dry pressing, used for flooring and walls indoors and / or outdoors

Skirting board: It is a lower frieze of a wall. Complementary piece of ceramics that is placed in the base.
Solar reflectivity: The LEED environmental classification system requests the solar reflectance index (ISR), especially for roofs / terraces. Color is the most important aspect for solar reflectance and SRI. The SRI is calculated in accordance with ASTM E1980-01, which describes the standard practice for calculating the Solar Reflectance Index of horizontal and low-slope opaque surfaces.

Thermal Conductivity: The physical property of materials that measures heat conduction capacity. In ceramic tiles it is less than 2.3W/m·K
Tone (Tone spectrum and texture): The tone sets the product's degree of coloration, brightness, the design's surface and texture. Tone and colour variations are natural in all wall and floor tiles, which are put through a firing process at high temperatures. Each piece experiences individual reactions that generate a slight variation on its glaze. This brings the piece nearer to its natural roots with which it is made up of. Variations on tone and colour are inherent in all ceramic products (those composed of clay) that are fired at high temperatures
