Question 4

The existence of ceramic slabs with different types of surfaces is the result of successful experiments by manufacturers. The most popular of them can be considered surface polishing (with its variations). Select the correct definitions or statements.

Score: 2.8571428571429 out of 10

Your Answer	Option	Right?	Result
	A polished surface is obtained by special matte polishing.		0
	When exposed to water, polished tiles become very slippery.		0
	Polished porcelain tiles are less slippery than polished ones, but due to the smooth surface of such tiles, they are easy to clean.		0
	Tiles with a matte surface are not only the most affordable, since they do not require additional processing, but also the most durable.		1
	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.		1
	To obtain polished tiles, their surface is polished with special diamond nozzles using a large number of chemicals.		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 matte surface is more slippery than, for example, polished or glazed.		0
	The tile that comes out of the kiln and is not subjected to additional mechanical treatment after firing has a matte surface.		0

Question 5

Glazed ceramic tiles can be used to cover walls and floors. Which of the following statements regarding glaze are true?

Score: 0 out of 10

Your Answer	Option	Right?	Result
	The chemical composition of the glaze and the ceramic shard is different. Their thermal expansion also varies in size.		0
	Frit is a special type of glass that, during the firing of the tile, melts and adheres tightly to the shard.		0
	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
	Glaze is a shiny or enamel glassy layer in the form of a thin film (1 - 3 mm).		-1
	Transparent glazes are also called enamels.		-1
	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
	Transparent glazes are colorless and colored.		1
	Glaze, consisting of frits only, is used only to achieve a shiny surface on some types of wall tiles.		0
