Some traditional Moroccan zellige glazes contain lead, while others have very low or nondetectable levels. Lead content depends on the glaze formulation, pigment, and manufacturing process, and deeper, more saturated colors tend to carry more. Tiles of Ezra has identified seven Moroccan zellige colorways with reported total lead levels below 100 ppm.

For this collection, lead-free refers to products that Tiles of Ezra reports as testing below 100 parts per million (ppm) for total lead. It does not necessarily mean absolutely zero lead, it is not a universal legal definition, and it is not equivalent to food-contact certification.

Zellige is a long-standing choice for kitchen backsplashes, but suitability depends on the specific product, glaze, installation, and intended use. Total lead content and potential lead release are different measurements, and surfaces where food sits directly call for closer review. As with any glazed tile, installers should control dust when cutting. For a particular product, consult the manufacturer’s testing information and technical specifications, or ask our team to help.

Total lead testing measures how much lead is present in a material. Leach testing measures how much lead may migrate from a fired surface under specified test conditions, and is the measurement typically used for food-contact applications. The two results answer different questions, which is why understanding the test method matters. Tiles of Ezra’s guide explains the distinction in detail.

Tiles of Ezra identifies qualifying products across Moroccan Zellige, Amano Ceramics, and Tierra Ceramics. The manufacturer reports seven qualifying zellige colorways, along with every Amano colorway and all ten Tierra colorways. Consult current manufacturer documentation for product-specific results.

Many zellige products are well suited to wet areas, but suitability depends on the specific tile, surface, installation, and manufacturer recommendations. Lead testing does not establish slip resistance, waterproofing performance, or floor suitability, so always review the technical specifications for your intended application.

Ask for manufacturer testing documentation that identifies the product, the test method, and the reported result. Quick on-the-spot readings are useful for screening but are not the same as laboratory results.
