Zellige special characteristics
Regarding the colour
Zellige is made by placing the different pieces in the oven in order to bake them. Depending on where each of these pieces is placed they will have different tonalities, as they may have received more or less heat intensity, this is its main sign of identity. Therefore, they might be variations of colours inside a zellige box as well as between different boxes.
That is why when it comes to placing the zelliges, it is highly recommended to take zelliges randomly from the same box as well as from different boxes, in order to avoid zones with high concentration of pronounced variations.
Regarding shape and finish
Due to the artisanal methods carried out during the whole manufacturing process, there will be small imperfections which taken isolated may seem less attractive, but in a global context they will be very subtle. Therefore, there is no reason to classify them in order to use only the “perfect” tiles. Up to 5% of small imperfections should be tolerated, as we can take advantage of these tiles and used them where cut tiles are needed for the finishes, and therefore there will be almost no leftovers. Our zellige is subject to a strictly selection during the manufacturing process, nonetheless, the craft feature that characterises it, impedes to achieve the uniformity of an industrial material.
