When you’re picking out a new ceramic piece, whether it’s a mug for your morning coffee or a serving platter for your next dinner party, you want to make sure it’s not only beautiful but also safe to use. One important factor to consider is the glaze – that shiny, colorful coating that gives pottery its character. Not all pottery glazes are created equal, and some may contain harmful substances that can leach into your food. So, how can you be sure the pottery you’re buying is finished with a Food Safe Pottery Glaze?
Understanding Food Safe Pottery Glaze
Pottery glaze is essentially a type of glass that is fused to the surface of the ceramic at high temperatures. This glass-like coating serves several purposes: it makes the pottery waterproof, adds durability, enhances its aesthetic appeal, and most importantly, when formulated correctly, makes it safe for food contact.
The concern with food safety arises from the ingredients used in some glazes. Certain pigments and metallic oxides, while creating vibrant colors and effects, can be toxic if they leach into food. Lead and cadmium are prime examples of such harmful substances that were used in ceramic glazes in the past and are still a concern, particularly with older or imported pottery.
How to Ensure Your Pottery is Food Safe
1. Buy from Reputable Sources
The most reliable way to ensure your pottery is finished with a food safe pottery glaze is to buy from reputable ceramic artists, shops, and manufacturers. These sellers should be knowledgeable about the materials they use and should be able to answer your questions about the glaze’s food safety.
2. Look for Labels and Certifications
Many countries have regulations in place regarding the use of toxic substances in pottery glazes intended for food use. Look for labels or stickers that indicate the pottery is “food safe,” “lead-free,” or “cadmium-free.” Additionally, some countries have specific certification marks for food-safe ceramics.
3. Do a Simple “Leach Test” at Home
While not foolproof, a simple home test can give you some peace of mind. Fill the pottery piece with hot, acidic liquid like vinegar or lemon juice and let it sit for several hours. Afterward, if you notice any discoloration of the liquid or a metallic taste, it’s best to err on the side of caution and avoid using that piece for food.
“When in doubt, it’s always best to contact the maker or seller for clarification on the glaze used. Food safety should never be compromised,” advises ceramic artist and instructor, Johnathan Miller.
4. Consider the Intended Use
If you’re particularly concerned about food safety, consider using certain pottery pieces for decorative purposes only. Ornamental pieces, vintage ceramics, and pottery from antique shops or flea markets may be better suited for display rather than dining.
