Why doesn’t the tile I purchased for my room addition match the tile (same series & color) I purchased last year?

Question #2 addresses this issue because such a situation is generally the result of receiving two different shades (dye lots) of tile that were produced at different times, possibly fired in different kilns, with slightly different glaze components. Many natural components are used to produce both the body and glaze of Marazzi products.
 
Each time raw materials for a glaze are obtained from a supplier, each time the components of the tile body are mixed, each time a tile is pressed and fired slight variations may result. Generally, this presents no problem because a customer receives the same shade (dye lot) for each purchase; however, in an installation that evolves over a period of time, it may not be possible to obtain the same shade as originally installed. In such an instance, be sure to request the original shade (dye
lot). If not available, request a sample of current shades for comparison before purchase or installation.
