In recent years, historians have speculated that one of the causes for the fall of the Roman Empire was due to its citizens having chronic lead poisoning. Lead is a toxic metal that was used in many applications in ancient times from makeup to medicines to glazed pottery. Indeed, today, the glazes and clays used in some modern pieces of pottery have traces of lead in them, which can cause a host of problems.
Exposure to lead over a long period of time is called chronic lead poisoning. Lead affects the body in many ways, but its most serious consequences happen upon the nervous system. Chronic poisoning can result in memory loss, confusion, depression, nausea, anemia, and loss of muscular coordination. Eventually, long term exposure to lead can cause to problems such as respiratory distress and kidney failure, both of which can lead to death.
Because of the dangers of lead poisoning, it is important to test your glazed potter for the presence of lead. Almost all commercially produced pieces of pottery are lead free and fit for using as dinnerware. However, handmade, artisanal pieces may contain lead, which precludes them from being used for eating or drinking. But why do potters and ceramic artist use lead in their products in the first place? Potter is made out of clay, which is very porous by nature. In order to seal the pores to make the pottery water proof, a glaze must be applied to fill all of the small holes and crevices. Not only does a glaze seal the holes, but it also provides a beautiful finish to the piece of glazed pottery, giving the surface a glassy look. Artists use lead in their glaze formulas in order to make the glaze melt more easily in the kiln. As the glaze bakes into the pottery, the lead that is in the glaze fuses to the clay, which contaminates it. If any food or liquid comes into contact with the surface, lead can leech into it and get ingested by the person using the plate, bowl, or cup.
If you have any glazed pottery around your home that you use to serve food or drinks, you need to test them for lead. You can do this by yourself by purchasing a lead testing kit at your local hardware store. These easy to use kits provide instant results that are clear and easy to understand. If you do find that your piece of glazed pottery does contain lead, do not eat off of it or drink from it. Instead, use it as decoration to maintain your good health.
