Physical Examination

Surface Smoothness

When examining pottery for food safety, one of the first things to consider is its surface smoothness. A smooth and non-porous surface is less likely to harbor bacteria and easier to clean thoroughly. Run your fingers over the pottery’s surface to check for any rough or uneven areas that may be harder to clean. Additionally, look out for glaze irregularities, as these may indicate manufacturing flaws that could compromise the safety of the pottery.

Presence of Cracks or Crazing

Cracks or crazing refers to the fine lines or cracks that appear on the surface of pottery due to stress or expansion and contraction. While small cracks may not always pose immediate safety concerns, they can trap bacteria or lead to further damage over time. It is generally advisable to avoid using pottery with significant cracks, as they may compromise its structural integrity and make it more prone to leaching or breakage.

Thickness and Durability

The thickness and durability of pottery are factors that contribute to its safety and longevity. Thicker pottery tends to be less likely to break or chip, reducing the risk of ingesting small particles. However, thicker pottery may also take longer to heat or cool, so it’s important to consider the intended use. Durability is also an important aspect, as overtly fragile pottery may be more prone to cracks or breakage during normal use.

Checking for Leaching

Food Contact Test

To ensure that pottery is safe for food use, it should undergo food contact testing. This testing involves exposing the pottery to specific foods or food simulants to assess if any harmful substances leach into the food. Some manufacturers may perform this testing in-house, while others may obtain certifications from independent laboratories. Look for pottery that has undergone food contact testing and has been deemed safe for use with food.

Microwave and Dishwasher Safe

Another way to assess the leaching potential of pottery is to determine if it is labeled as microwave and dishwasher safe. Pottery that is microwave safe indicates that it can withstand the heat generated by microwaves without leaching harmful substances. Similarly, pottery labeled as dishwasher safe means it can withstand the high temperatures and detergents used in dishwashers without any adverse effects. These labels provide added assurance of the pottery’s safety and suitability for food contact.

Testing for Lead Content

Lead Testing Kits

If you have concerns about the lead content of your pottery, you can use lead testing kits to detect its presence. These kits typically include swabs or test solutions that can be applied to the pottery surface. The solution changes color if lead is detected. While these kits can provide a quick indication of lead presence, they may not provide precise measurements or detect lower levels of lead. Consider professional laboratory testing for more accurate results.

Professional Laboratory Testing

For a comprehensive assessment of your pottery’s lead content, professional laboratory testing is recommended. There are specialized laboratories that offer lead testing services for pottery and other consumer products. They use advanced testing methods to accurately measure the lead content and identify any potential health risks. Choose a reputable laboratory with expertise in pottery testing to ensure reliable results and peace of mind.

Water Absorption Rate

Understanding Absorption Rate

Water absorption rate refers to the ability of pottery to absorb water. Highly absorbent pottery may absorb liquids from food, potentially leading to contamination and odors. Pottery with low water absorption rates is generally considered more food safe, as it restricts the passage of liquids into the body of the pottery. Understanding the absorption rate of your pottery can help you make informed decisions about its suitability for food use.

Testing for Absorption

To determine the absorption rate of your pottery, you can perform a simple test at home. Fill a clean cup or bowl with water and place your pottery, specific side down, into the container. Allow it to sit for a few hours or overnight. After the specified time, remove the pottery and check for any visible signs of moisture absorption or discoloration. If the pottery remains dry and unchanged, it likely has a low water absorption rate and is suitable for food use.
