perfectly imperfect moroccan zellige tile
clé is honored to share one of our all time favorite materials that has graced the tile community since at least the 14th century. zellige is a tile that has retained its ancient and archaic tile making process and, therefore, has all the primitive qualities that have become synonymous with the monicker - zellige. essentially, a glazed terracotta tile; hand hewn, olive-pit fired and hand chiseled to-size, zellige are a testament of ancient tile craft. we like to refer to them as the prima materia of the tile world. If your order doesn’t contain tiles with pits, cracks, shade/size variations and chipped edges - it is NOT authentic zellige.
zellige is a series of glazed terracotta tile, handmade in morocco. It is a low-fired terracotta that is used throughout morocco for all applications- floor and wall, interior and exterior, and water treatments ( pools and fountains ). available in a variety of sizes, and colors, zellige is a prestigious architectural finish for the finest projects. they may be installed using most industry accepted processes, typical for standard ceramic installation on a variety of substrates.
zellige glaze colors vary from tile to tile, some more than others. these variations are intentional, resulting from our commitment to the use of ancient glaze production methods and use of raw materials. when specifying zellige, if color consideration is paramount, always work from a sampling of 3 or more tiles, which represent the range of color you can expect on the job. unglazed zellige - referred to as the color “natural”– will require the same sealant methods as our standard unglazed tile sealing.
crazing refers to the hairline cracks which may occur in the glaze surface of zellige after firing and is common in hand crafted tile. to minimize the possibility of staining clé recommends using a penetrating sealer or grout release. If sealer or release is required, please test a small section following the sealer/release manufacturer’s instructions.
all zellige are hand chiseled to size. this creates obvious size variation which is part of the zellige effect. please anticipate size variation in width and length, based on this chiseling. due to shrinkage from wet to fired clay in the firing process, our tiles are subject to size variation in depth, as well. the thickness is 3/8" ( for all sizes except 2"x5.5". that thickness is 3/4")and can vary, along with other specified dimensions.
pitting, cracking & edge-chipping
again, based on the archaic methods of the mining and firing of the terracotta zellige clay body and the impurities found in the raw materials used for the glazes, your order of zellige will contain tiles that are pitted through the glazes to the clay body, as well as have a percentage of about 20%-30% that will contain cracks, crazing and edge-chipping. should your project not want as many tiles containing these imperfections - order at least 20%-30% more tiles, to allow your contractor to cherry-pick these imperfections from your order.
note - clé does not suggest this recommendation as a preferred form of zellige installation, as it falls outside a standard zellige finish and will not yield your project the traditional zellige surface for which they are known.
blending before installation
DO NOT install from unblended boxes. zellige from several different cartons should be mixed to achieve the best overall blend of color and surface imperfections. other systems are available and the manufacturer’s recommendations should be followed.
