Your Answer	Option	Right?	Result
	A matte surface is more slippery than, for example, polished or glazed.		0
	Polished Surface - The surface of glazed or unglazed ceramic tiles and slabs that is polished at the final stage of manufacture to impart shine.		0
	A polished surface is obtained by special matte polishing.		0
	When exposed to water, polished tiles become very slippery.		1
	Tiles with a matte surface are not only the most affordable, since they do not require additional processing, but also the most durable.		0
	To obtain polished tiles, their surface is polished with special diamond nozzles using a large number of chemicals.		0
	When polishing, the topmost “sintered” layer is cut off. As a result, polished porcelain stoneware is slightly inferior to matte in terms of performance characteristics, in particular, wear resistance.		0
	The tile that comes out of the kiln and is not subjected to additional mechanical treatment after firing has a matte surface.		1
	Polished porcelain tiles are less slippery than polished ones, but due to the smooth surface of such tiles, they are easy to clean.		0

	Actual size - The size obtained by measuring the surface of ceramic tiles and slabs in accordance with EN ISO 10545-2.		0
	Technological size (W) - A size established for the manufacturing process of ceramic tiles and slabs, which must correspond to the actual size within acceptable deviations.		0
	Coordination size (C) - Technological size, including the width of the seam.		0
