The invention relates to a wear indicator (display) in a compound system made of fireproof (refractory) ceramic bricks. 1. Wear indicator in a compound system made of fireproof ceramic bricks (A) with the following characteristics:{'b': 10', '1', '10', '2', '10', '3, 'a.) the wear indicator consists of a set of at least two ceramic components (., ., .),'}{'b': 10', '1', '10', '2', '10', '3', '10', '1', '10', '2', '10', '3, 'b.) each component (., ., .) features at least one surface segment with a three dimensional profile (P, N), wherein the profiles (P, N) of corresponding surface segments of adjacent components (., ., .) complement one another in a form fitted manner,'}{'b': 10', '1', '10', '2', '10', '3, 'claim-text': c1.) only over a partial length, or', 'c2.) with a different geometry, or', 'c3.) only over a partial length with a different geometry., 'c.) in the direction of wear (Y) of the components (., ., .), the profiles (P, N) extend'}2. Wear indicator according to with at least one profile (P claim 1 , N) from the group: bar claim 1 , step claim 1 , spike claim 1 , bolt claim 1 , pin claim 1 , rib claim 1 , pyramid claim 1 , sawtooth claim 1 , hole claim 1 , channel claim 1 , groove claim 1 , prism claim 1 , ellipse claim 1 , pitch circle.3. Wear indicator according to with at least one profile (P claim 1 , N) which claim 1 , in the direct of wear (Y) claim 1 , enlarges in a direction (X claim 1 , Z) perpendicular to the direction of wear (Y).4. Wear indicator according to with at least one profile (P claim 1 , N) which claim 1 , in the direct of wear (Y) claim 1 , downsizes in a direction (X claim 1 , Z) perpendicular to the direction of wear (Y).5101102103. Wear indicator according to wherein at least one component (. claim 1 , . claim 1 , .) changes its width (B) claim 1 , perpendicular to the direction of wear (Y) claim 1 , in the direction of wear (Y).6. Wear indicator according to wherein at least one component changes its height claim 1 , ...
