![]() Glass, on the other hand, is safe except when it is painted, colored or decorated. Since it is not easy for me to test lead and cadmium contained in the mugs before I buy mugs, I don’t like mugs that are made of these materials. Ceramic, porcelain, china or bone china mugs often have glaze with lead or cadmium to look brighter, shinier and colorful. Just like dinnerware, mugs also can contain lead and cadmium. Non Toxic Mugs – Finedine Insulated Stainless Coffee Mugsįinedine insulated stainless steel coffee mugs come with lids. Stainless steel is also a non toxic material that I enjoy using for food and drinks. I have also added some stainless steel coffee mugs. Some glass mugs are insulated so you can keep the temperature of drink hot or cold for a long time. Some mugs are made of borosilicate glass. Borosilicate glass has extreme resistance to severe temperature changes and thermal shock. I have listed non toxic glass mugs below. Therefore, avoid glasses with paints and decorations and go for the plain, clear glass material. That is a lot of lead and cadmium found on glasses! The limit levels for the externally decorated lip area of drinking glass are 200 ppm and 800 ppm according to the US Office of Environmental Health Hazard Assessment. Glass material normally does not contain glaze unless it has painted or decal-type decorations.Ī study by the University of Plymouth in UK found lead and cadmium in both the paint and glaze of decoration on the outside of the glassware and around the rim. The lead concentrations ranged from about 40 to 400,000 parts per million (ppm), while cadmium ranged from about 300 to 70,000 ppm. Since any ceramic, porcelain or china mugs can contain lead or cadmium from their glaze, I like the mugs that are made of glass. However, I don’t have the proper testing instrument and even if I do, I am not going to test every mugs before I buy. In order to find out how much lead or cadmium is present in the mugs, each mug has to be tested. Microwaving a mug that contains lead or cadmium will also make leaching of toxicants easier and faster. Therefore, it will not be good for a coffee drinker to drink coffee in a mug that contains lead or cadmium. Unfortunately, coffee which many people drink daily, sometimes several times a day is acidic. (except leaded crystal which contains lead as an ingredient)Īcidic food or drinks will make these materials leach lead or cadmium easier and faster. For Glass mugs, if they are colored, painted or have decal-type decorations on the surface, they will most likely contain lead or cadmium. Even nowadays, some fine chinas contain lead and cadmium regardless of their color and decals. FDA started testing for safety starting 1970, therefore, most vintage china will contain high levels of lead and cadmium. Whether they are plain white, colored or decorated, they all have a chance to contain lead or cadmium. Since small traces of lead or cadmium is allowed in dinnerware and mugs sold in the United States, many mugs contain lead or cadmium. Cadmium is often used to provide dishes bright colors. Lead glazes and decorations are also commonly used on porcelain or fine china. Lead is usually used to make glazes look shiny and smooth. Heat will increase the amount of toxins leaching into drinks faster.Ĭeramic mugs have glazes and decorations that usually contain lead or cadmium. Plastic is a hazardous material to begin with and very bad when mixed with heat, therefore, I wouldn’t choose the material especially for drinking hot beverages. Mugs can be made with plastic, ceramic, porcelain, bone china or glass. In this post, I share with you how mugs can be toxic and what non toxic mugs are available. That means most of the mugs out there may have lead or cadmium. Since I use a mug everyday, I wanted to get a mug that is non toxic and cadmium & lead-free. Unfortunately, so many mugs contain lead or cadmium. A study by the University of Plymouth in UK found 70% of glasses they tested (out of 72 products) contained lead and cadmium. Therefore, having a mug that doesn’t contain lead and cadmium is important especially for a coffee drinker like myself. Coffee is actually acidic so it makes the mug leach lead or cadmium faster. However, a mug can be toxic and leach harmful lead and cadmium. Many people have their favourite mug they use on daily basis. I am a coffee drinker so I use a mug everyday.
