The Sad News About Your Favorite Teacup and Why You Need to Take Caution

By Erika Robertson

Tea is posh. Tea is casual. Tea is a part of everyday life and special occasions. It is always a good time for you to have tea. When you sip a cup of fresh tea you invite all your senses to mingle and relax. 

Tea makes the world go round. Aside from water, tea is the most popular drink on the planet. A cup of tea is healthy. A mug of tea is affordable. And afternoon tea is delectable. — But, tea can be dangerous. 

Here’s the bad news: It’s likely that the adorable tea mug is poisoning you with a daily dose of toxic chemicals.

Here’s the good news: You can take your tea routine to the next level by switching out that porcelain mug for a better option that helps your health and sustains the planet.

Are Your Cute Tea Cups and Coffee Mugs Toxic?

You, like most tea drinkers, sip your favorite teas from porcelain or metal cups and mugs. Your mornings, afternoons, and evenings are full of tea. 

Your tea ritual starts by picking out your “tea cup of the day”. You get to choose from your favorite flower-painted and cat-adorned ceramicware. 

Tea is your daily retreat from life or it’s the boost to keep you moving. But this ritual is one that might have a steep cost on your health.

Most teaware and tea cups have a long and rocky history with their manufacturer’s chemicals and toxins. Ceramic cups are made using porous materials. These materials are painted with glaze to help keep moisture out. 

Ceramic materials aren’t an issue but the painted glaze may be toxic.

The Negative Effects of Toxic Stoneware Mugs and Cups

Most coffee mugs and tea cups have cadmium, lead, and other materials. Drinking from lead-glazed cups is an enormous public health problem. The FDA states that the glaze used in making ceramic ware can contain cadmium and lead.1

Ceramicware includes porcelain and metallic tea cups and mugs. Metallic teaware has high levels of nickel, lead, and other toxic chemicals.2 Long-term lead exposure can cause weakness, brain damage, anemia, kidney failure, and in some cases death.3 Prolonged exposure to Cadmium has terrible effects including cancer and organ system toxicity.4

Lead-free or Lead-safe? And What is Leaching?

A majority of teaware companies say that they produce lead-free tea cups and teapots. But, did you know that a lot of these companies don’t know what chemicals are used in the glaze of their porcelain tea cups?

Sometimes these companies refuse to comment on the chemical breakdowns of their glazes. Manufacturers might even use unapproved glazes that weren’t tested by the teaware companies. Sometimes, there are big trust issues when it comes to creating quality teaware.

Learning the differences between lead-free tea cups and lead-safe tea cups is important. And it’s good for you to know how leaching affects your tea:

Lead-Free Teacups and Mugs

Lead-free tea cups and mugs don’t have any traces of lead. Trust is a big concern between teaware companies and manufacturers. There’s never a solid guarantee that your glazed porcelain tea cup is lead-free. 

Are you concerned that lead is in the glaze or paint of your favorite tea cup? You can buy a lead-testing kit online and test it at home.  

Lead-Safe Teacups and Mugs

Lead-safe tea cups and mugs have very small traces of lead paint. The lead in the paint doesn’t exceed two or three parts per million.5 

These decorative paint designs are usually found outside of your tea cup. The paint doesn’t come into direct contact with your tea. This means lead doesn’t leach into your beverage.

What is Leaching?

Leaching happens when lead paint chips off of your tea cup or seeps into your tea. Heavy leaching may occur when hot or acidic teas come into contact with the porcelain glaze. 

Lead-free tea cups will not leach chemicals into your tea. Lead-safe tea cups generally don’t carry the risk of leaching toxic chemicals into your tea.

What is the Most Non-Toxic Material?

Research and study show that the safest and purest material for tea cups and mugs is a special kind of glass. Borosilicate glass tea cups and mugs are the best material for your teaware. 

Borosilicate glass tea cups don’t leach toxins and chemicals into your tea. Borosilicate glass has a great reputation for quality and long-lasting safety. Its benefits eclipse the negative health impacts of metallic and porcelain tea cups.
