Is it safe to drink out of glazed pottery?

Drinking vessels made from glazed pottery are commonly used for various beverages, from tea and coffee to water and juice. Glazing provides a protective and decorative layer on the pottery surface, but is it safe to use glazed pottery for drinking? Let’s explore the safety considerations of drinking out of glazed pottery and the factors that ensure the suitability of glazed vessels for beverage consumption.

Food-Safe Glazes

Glazes that are labeled as “food-safe” or “lead-free” are formulated to meet strict safety standards and regulations. These glazes are tested to ensure that they do not leach harmful substances into food or beverages, making them safe for consumption.

Kiln Firing

Kiln firing plays a crucial role in making glazed pottery safe for use. During firing, glazes undergo chemical transformations that bond the glaze particles to the pottery surface. Properly fired glazes create a glassy and non-porous barrier that prevents liquids from interacting with the clay beneath.

Use of Unsafe Materials

Using glazes or materials that contain toxic substances, such as lead, cadmium, or other heavy metals, can pose health risks if they leach into beverages. It’s important to use glazes from reputable sources that provide information about their composition and safety.

Cracks and Damage

Cracks, chips, or damage to the glaze can compromise the safety of glazed pottery. Liquids can seep into these imperfections, potentially leading to bacterial growth. It’s essential to regularly inspect glazed vessels for any signs of damage.

Care and Maintenance

Proper care and maintenance of glazed pottery contribute to its safety. Wash glazed vessels with mild soap and water, and avoid abrasive scrubbing that could damage the glaze. Allow the pottery to dry thoroughly between uses.


When made with food-safe glazes and properly fired, glazed pottery is safe for drinking and food consumption. To ensure the safety of glazed vessels, use reputable glazes, inspect for damage, and follow proper care and maintenance practices. By doing so, you can enjoy your favorite beverages in beautifully crafted and safe glazed pottery.
