Your Answer	Option	Right?	Result
	Transparent glazes are colorless and colored.		1
	Transparent glazes are also called enamels.		-1
	Glaze, consisting of frits only, is used only to achieve a shiny surface on some types of wall tiles.		0
	The chemical composition of the glaze and the ceramic shard is different. Their thermal expansion also varies in size.		1
	Tsek is a type of glaze defect. This occurs due to the difference in the expansion coefficients of the shard and the glaze itself. The center has the appearance of web-like cracks.		1
	Frit is a special type of glass that, during the firing of the tile, melts and adheres tightly to the shard.		0
	The fragility of the adhesion of the glaze to the shard is expressed in the formation of a network of cracks in the glaze layer (cek) or the detachment of the glaze from the shard after firing and cooling.		0
	Glaze is a shiny or enamel glassy layer in the form of a thin film (1 - 3 mm).		-1

	Modular size - Dimensions of ceramic tiles and slabs determined on the basis of module M, as well as their multiple and divisible, with the exception of tiles and slabs with a front surface area of less than 9000 mm2. NOTE See ISO 1006, where 1M = 100 mm.		0
	Coordination size (C) - Technological size, including the width of the seam.		1
	The dimensions of tiles and slabs of other shapes are determined by the largest size of the rectangle in which they are inscribed		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
	Non-modular dimensions - Dimensions that do not take into account the modular (M) structure. NOTE See ISO 1006, where 1M = 100 mm.		0
