Lead is a metal that has been used in manufacturing for centuries. It’s found in many products, including ceramics. But lead glaze can be hazardous if it’s not managed correctly.
So it is essential to know how to test for lead in ceramics. If your clay contains enough lead before making ceramics, it will be toxic and could cause harm.
When working with pottery, it is advisable to take precautions to avoid any potential hazards.
What Is Lead and Why Is It Dangerous?
Lead is a bluish-gray metal that has been used since ancient times to make many products, including ceramics. It’s found in several elements and minerals.
Since pottery production began thousands of years ago, it’s impossible to precisely know which pottery items contain lead without testing them properly.

How to Test for Lead in Ceramics Using a Lead Testing Kit?
The following is a guide on how to determine if ceramics contain lead by a lead test kit.
Pick Up a Lead Testing Kit
The first thing you need to do is pick up a lead testing kit. It can be purchased online. There are many types available from which you can choose one that suits your needs.
Clean the Ceramic
You should clean the surface of your ceramic dishes before testing for lead. Wipe it down with a dry cloth or paper towel to eliminate any grime, dust, dirt, residue, and oil.
Scrape Some Glaze
Take a metal object like an ice cream stick and scrape off some ceramic glaze from the surface of your ceramic ware. You should aim to get a pea-sized amount of glaze, but it doesn’t have to be exact.
Put on Gloves
You should wear gloves while scraping off some glaze paint and taking the sample, primarily if you’ve previously handled lead products without protective equipment.
Put the Glaze into A Plastic Bag
Put the scraping from your ceramic ware into a plastic bag, seal it shut, and label the bag with your name and the date you took the sample.
Submit the Sample
Send or take your lead testing kit samples to an accredited laboratory for analysis.
These are the steps involved in testing for lead dust in ceramics using a lead testing kit.
What to Do If Your Ceramic Contains Lead?
If the lead test result shows that your ceramic ware contains higher-than-acceptable lead levels, you should take precautions.
Store the Ceramic Ware in A Safe Place
It would help store the ceramic ware in an area where children cannot access lead residue. If you intend to repurpose the item, ensure it’s thoroughly cleaned and disposed of properly.
Limit Contact with Children
Since children are more at risk than adults when exposed to lead, you should avoid contact with your dishware. If possible, keep it in an area where children can’t go.
Cover Food and Drink
Cover your food and drinks when using ceramic ware that contains lead, especially if any of the glazes has been chipped away. This will prevent the lead from getting into your body.
Stop Using the Items
You should stop using your ceramic ware if it contains high lead levels. You can have them tested again to see if they are usable or not, but remember that some ceramics may still have lead even after the second test.
Get Your Children Tested
It would help if you asked your doctor to test your children for any signs of lead poisoning.
Contact the Supplier
Contact the manufacturer and let them know if you’ve discovered that their product contains lead. They may provide you with more information about how they produce their products and what types of precautions they take.
Report the Problem
If you have purchased a ceramic dish that contains high lead levels, you should report it to your local authority. The seller may be fined or prosecuted if they break the law by providing lead-contaminated products for sale.
What Happens If You Have Lead Poisoning?
If your ceramic ware contains lead and you come into contact with it, you could suffer from lead poisoning.
Lead poisoning in adults may cause serious symptoms, including:
1. Joint Pain
You may have aching joints and muscles, especially in your hands and feet. This is usually the first sign of lead poisoning for adults.
2. Blood Pressure
If you have elevated blood pressure, you likely suffer from lead poisoning.
3. Seizures or Memory Loss
Lead poisoning could trigger seizures or cause memory problems. If your lead levels are high enough, you may also experience delirium and hallucinations.
4. Organ Damage
You may experience organ damage if you’re exposed to high levels of lead. This could affect your kidneys, digestive system, nervous system, reproductive organs, and more.
You may have frequent headaches if you have lead poisoning. You should see a doctor immediately if you suffer from chronic headaches or migraines because this could indicate lead exposure.
Children under the age of six are particularly vulnerable to lead poisoning. Common symptoms include:
1. Learning Disabilities
If your child is suffering from lead poisoning, they may have difficulties learning abilities. This includes problems concentrating and paying attention and having behavioral issues at school or home.
Young children with lead poisoning may appear tired and sluggish. They may also be less aware of what’s happening around them than their peers. This is because the blood-brain barrier doesn’t fully develop until adulthood, meaning that any toxins in a child’s body can reach their brain more easily.
3. Weight Loss
If your child is suffering from lead poisoning, they may lose their appetite. This will make them lose weight even when they are regularly eating. The lack of nutrition means that your child’s body won’t develop properly.
If your child is showing symptoms of irritability when they are generally calm, it could indicate that they have lead in their system. Lead poisoning may also trigger behavioral problems at school or in the home.
5. Hearing Loss
Some young children with elevated levels of lead suffer from hearing loss. As they grow older, this may cause developmental problems, so check for other symptoms if your child is hard of hearing.
6. Abdominal Pain
Children who have lead poisoning may also show signs of abdominal pain as a symptom. This could be a sign that there’s lead in their system, and it should be taken seriously.
Precautions You Can Take When Working with Pottery
Lead testing isn’t the only way to protect yourself and your family from lead. There are several precautions you can take when working with pottery:
Use a Dust Mask
It would help if you used a dust mask or any other protection against dust while working with ceramics, including gloves and glasses. This will prevent lead particles from getting into your system.
Wash Hands Thoroughly
After you’ve finished working on ceramics, wash your hands thoroughly to remove any lead particles that may be present.
If possible, stick to disposable gloves instead of washing them, so you don’t have to touch the lead directly. It would help if you also used an electric mixer when pottery since it doesn’t create as much dust.
Avoid Using Glazes That Contain Lead
If you’re using a commercial glaze, make sure they don’t contain lead. You can also try making your own glazes and ask the manufacturer if their product has lead or not before buying it. This will help you avoid using products that may harm your health.
Wash Glazes Off Your Hands
If some of the glazes get onto your hands, you should wash them off as soon as possible to avoid any exposure to lead. You can use soap and water or a commercial product made specifically for cleaning pottery after working with ceramics.
Dispose of Any Unusable Ceramics
If your lead test result shows that your ceramic ware contains high lead levels, you should discard them.
If you’re unsure whether the items have too much lead for use, check with the manufacturer or send it to an accredited laboratory for testing. You can also repurpose or recycle them to reduce the amount of waste in your home or workplace.
So, as you can see, there are several precautions you can take when working with pottery to protect yourself and your family from lead poisoning. By following the tips we’ve provided, you can ensure that everyone stays safe while enjoying this popular hobby.
And if you’re ever unsure about whether a product contains lead or not, don’t hesitate to reach out to the manufacturer for more information. Thanks for reading.
