Zellige tile is one of the most distinctive decorative materials in the world — hand-cut, hand-glazed, fired in traditional kilns, and made in a single city: Fez, Morocco. This guide covers everything: what it is, how it’s made, how it differs from imitations, and how to use it in your home.

What is Zellige Tile?
Zellige (also spelled zellij, pronounced zeh-leej) is a form of hand-cut ceramic mosaic tile originating from Fez, Morocco. The word comes from the Arabic al-zulayj, meaning “small polished stone.”
Each zellige tile begins as a 4″×4″ square of fired clay hand-cut by a master craftsman called a maalem using a small chisel and hammer. The cutting happens against the unglazed back face, fracturing the clay along the intended line and creating the slightly bevelled, irregular edges that give zellige its characteristic light-catching quality.
No laser cutter. No water jet. No machine die. Just a chisel, a hammer, and hands trained over years.
Key fact
A master zellige cutter (maalem ezzellij) trains for 3–5 years before working production tiles. The precision of the hand fracture — which creates zellige’s distinctive bevelled edge — cannot be replicated by any machine without losing what defines authentic zellige.

A Thousand Years of Craft
Zellige craft emerged in Fez in the 10th century during the Idrisid dynasty. The city’s unique clay — from local quarries with a specific mineral composition — proved ideal for the technique. Within two centuries, zellige had become the defining decorative element of Moroccan royal architecture.
The great monuments of Fez — the Al-Qarawiyyin mosque (the world’s oldest continuously operating university), the Bou Inania madrasa, the Saadian Tombs in Marrakech — are all clad in zellige made by the same families, using the same techniques, that produce tile today.
Fez remains the only place in the world where authentic zellige can be made. The mineral composition of Fez clay, the way it fires, and the specific techniques of the Fez maalem are inseparable from the result.
How Zellige is Made: The 9-Step Process
Understanding how zellige is made explains why it takes 3–8 weeks to produce and why no two pieces are identical.

View Production Process →Real Zellige vs. Imitations
The global popularity of zellige has created a market for machine-made imitations sold as “zellige-style” or “handmade Moroccan tile.” Here’s how to tell the difference:
| Feature | Authentic Zellige | Machine-made Imitation |
|---|---|---|
| Edge profile | Slightly bevelled, irregular — chisel fracture | Perfectly square, uniform — machine cut |
| Surface texture | Slight irregularity, glaze depth varies | Uniform, flat, consistent |
| Glaze depth | Luminous, three-dimensional — dip-glazed | Flat, printed or spray-applied |
| Colour variation | Natural batch variation — intentional | Perfectly uniform |
| Light behaviour | Scatters light at multiple angles | Reflects light uniformly |
| Origin | Made in Fez, Morocco only | Spain, Italy, China, or unknown |
| Certification | Zellige de Fès Quality Label | Not eligible |
The easiest test: hold a piece at a raking angle under a light source. Authentic zellige scatters light in multiple directions. A machine-made tile reflects it uniformly, like a mirror.
On “handmade” claims: Many tiles sold as “handmade Moroccan tile” are made in Spain, Portugal, or China. Hand glazing alone does not make zellige. The hand-cut chisel fracture, Fez clay, and double kiln firing are all required. The Zellige de Fès Quality Label is the only official certification.
The Zellige de Fès Quality Label
My Moroccan Tile is the only source in North America carrying the Zellige de Fès Quality Label — Morocco’s official government certification for authentic zellige. Every tile we sell is made in our own factory in Fez and carries this mark.
To carry the label, a producer must meet strict criteria:
- Clay sourced exclusively from the quarries of Fez
- Traditional hand-cutting by trained maalem artisans
- Double kiln firing in traditional kilns
- Production facility physically located in Fez
- Quality inspection of finished pieces before packing
We own our factory in Fez. We employ our artisans directly. We have carried the certification since 2007. No other supplier in the United States or Canada holds this certification.

Kitchen Backsplash
The most popular application. A zellige backsplash transforms a kitchen from functional to extraordinary. The irregular surface catches kitchen light in ways flat tile cannot. Popular choices: white or bone, deep navy, forest green, and custom colour matches to cabinetry or countertop.
Bathroom & Shower
Zellige performs exceptionally in wet areas. The double-fired glaze is water-resistant and easy to clean. Our most dramatic projects use zellige floor-to-ceiling, creating an immersive environment.
A real client installation: Chellah mosaic zellige in a master bathroom. Floor-to-ceiling in a custom colourway.
Outdoor & Pool
Traditional zellige has been used in Moroccan courtyards, pools, and fountains for centuries. The fired clay body handles temperature variation well; the glaze resists chlorine and UV.
Fireplace Surround
A zellige fireplace surround is one of the most effective feature moments in a home. Fish scale, star and cross, and geometric mosaic patterns are particularly popular here.
Stair Risers
One of the most striking and underused applications. Terracotta or glazed zellige stair risers create a dramatic feature staircase with modest tile quantity.
Fountains & Water Features
We produce complete mosaic fountains in our Fez factory — designed, tiled, and finished before shipping. They arrive ready to install.
Installation and Care
Zellige requires an installer experienced with handmade or natural stone tile. The irregular surface and varied joint width are intentional — an inexperienced installer may try to “correct” them, disrupting the aesthetic.
- Adhesive: Flexible thin-set mortar for ceramic or mosaic tile. Waterproof mortar for wet areas.
- Grout: Non-sanded grout to prevent scratching the glaze. Apply in small sections, clean immediately.
- No spacers: The natural variation in joint width is part of authentic zellige. Spacers create a machine-made look.
- Sealing: Seal tiles and grout with a penetrating sealer. Use pH-neutral cleaner for maintenance.
Order 15% extra
Always order 10–15% more tile than your measured area. Irregular cuts create more waste, and ordering extra from the same batch ensures colour consistency. A later order may not match exactly due to natural batch variation.
How to Buy Authentic Zellige
70% of our sample orders become full projects. The tile sells itself once you’re holding it. Start with samples — it’s the fastest path to a finished project.
