The values given in the table are the most common or generally accepted for each product, hence they are only estimates. To identify what group of the standard they actually belong to, you shall refer to section 'Standard classification'.

	DENOMINATION AND USE
	It is the traditional name for high porosity ceramic tiles that are dry pressed, glazed, with the application of double or single firing. Their characteristics make them apt mainly for use as interior wall-coverings in buildings, houses or shops.
	PRODUCTION IN SPAIN
	The tiles, together with stoneware paving, make up the greater part of Spanish ceramic tile productions. A wide and varied offer is available.
	THE BATT
	The batt or bisque is made of majolica (fine earthenware) coloured white or clear (slightly grey, cream or ivory) or ochre to buff or dark red, without the colour affecting the characteristics of the product. The grain is fine and homogeneous and the non-homogeneous elements cannot be perceived by the naked eye (grain, inclusions, and pores).
	THE GLAZE
	The glaze that covers the face of the tile may be white, single-coloured, marbled, mottled, and multi-coloured and may be decorated with different motifs. The surfaces and arrises of the tiles are regular and well-finished. The predominant shapes are squares and rectangles. Standard complementary tiles are listels, mouldings and friezes.
	CLASSIFICATION STANDARDS
	Tiles are included in the BIII group of the ISTO 13006 and UNE EN 14411 standards (Dry pressed ceramic tiles with E > 10% water absorption).
