Are Copper Mugs Poisoning You?

What you need to know about the safety of copper cookware and drink ware

Copper, the pinkish-orange brassy metal that coats our pennies can also be found in the kitchen! We often see copper in those fancy mugs known for serving Moscow mules, but it is also found in other kitchenware like pots and pans. You may have seen some articles or blog posts warning about the dangers of kitchenware made of copper, or other voices claiming this fear is unnecessary and that these dishes and mugs are completely safe. Or, maybe you've never thought twice about it. Well…what's the deal?! Here we will clear up this mystery so you can feel comfortable and safe sipping on your refreshing Moscow Mule.

Copper Exposure and Health

Copper is a naturally occurring metal used industrially for electrical wiring, pipes, and other metal products and used agriculturally and in healthcare as an antimicrobial agent or contraceptive. Copper is an essential element, meaning that humans require some level of copper in our bodies(1). However, at high levels, (above 1,300 parts per billion), ingesting copper can irritate your digestive system and cause nausea, vomiting, stomach cramps, and diarrhea (2).

So, how are humans exposed to this metal? Like other metals, copper, when in contact with a liquid has the potential to leach off and become dissolved in the liquid. When consuming the liquid, any leached copper will be ingested and could cause the unfortunate digestive irritation mentioned above. The rate of this dissolution reaction depends on the properties of the metal, the properties of the liquid, and the temperature of these substances.

Copper in the kitchen is most commonly found in the form of mugs, or cookware like pots and pans. Copper kitchenware is sold either lined, meaning the inside is coated with a different, less corrosive metal, or unlined, where the item entirely copper. Going back to our fun chemistry lesson above, the potential to ingest copper at home (or at the bar!) comes from the possibility of the copper leaching into whatever substance you are cooking or drinking. So, the big question: Will the copper in your kitchen products leach and cause toxicity? In short, probably not.

Mugs – Although copper does leach faster than most metals used in cups, it would take many, many hours of sitting in the mug before your Moscow Mule became dangerous to drink (3). Of course, Moscow mules are not the only drink served in copper mugs, and other substances can behave a little differently. Most beverages are OK, but acidity and heat speed up the dissolution reaction (4). Something as acidic as lime juice would still take a few hours to leach, but to err on the side of caution, leaving hot and/or acidic substances in unlined copper dish ware should be avoided (3).

Pots and Pans – Because of the high temperatures used when cooking, unlined copper cookware should not be used (4)! The good news—nearly all copper cookware on the market is lined with a different metal. However, you can never be too careful! When cooking with copper items, make sure the inside is a different color, or that the label specifies "lined" to be certain that it is safe to use.

Pipes – The most common way humans are exposed to ingested copper is through tap water when copper faucets or storage pipes are used. If you are concerned about your water at home, run the water 15-30 seconds prior to drinking (2).

Our Advice

Don't fret about enjoying a drink out of a copper mug! If you are investing in new copper mugs, we recommend purchasing stainless steel-lined ones, but regardless there is no need to panic. If you have unlined mugs, just take care to ensure super hot or acidic substances don't sit in them for extended periods of time, and be extra cautious around children. As for pots and pans, invest in lined copper only. If you're on the market for some new copper kitchenware, here are some lined options pots, pans, and mugs. Now enough anxiety about copper, it's time to sit back, relax, and enjoy that Moscow mule!

Keep These Common Household Items Out of Reach From Teething Babies

And why we recommend always having a safe teether on hand

We're all guilty of just letting our teething baby chew anything they can get their hands on. What's the harm as long as it's not a choking hazard? A little dirt is good right? Turns out, there are some common household items that you definitely don't want your kids to chew on because they contain toxic chemicals or substances like lead and flame retardants. We recommend always having a safe teether on hand, whether you're at home or on the go. Even though common everyday items may look harmless, there can be unsafe substances that your little one can ingest if they're chewing on them.

Wondering what household items could be harmful to chew on? Here are some common items that you shouldn't let your little one chew on, even though it's so tempting to let them gnaw.

Keys

Keys are always in our purses or pockets and babies are fascinated with them. Sometimes they're the perfect distraction to avoiding a meltdown in the grocery story line. But it's actually not a good idea to let your little ones chew on keys or even play with them. The metals used to make keys vary greatly, but many brass keys can contain up to 2.5% lead (1,2). Even keys that don't look like brass might be plated in another metal, which can wear off over time. Not all keys contain lead, but it's impossible to know for sure which ones do and don't. So pick one of our safe teethers, including these Kleynimal Stainless Steel Keys, and make sure to pack it for your next grocery run.

Remote Controls

Remotes have colorful buttons and fit perfectly in little hands, so it's no wonder you always see babies chewing on the ends. But remotes contain batteries, which are not safe anywhere near your child's mouth. Additionally, household electronics like remotes contain flame retardants, which can come off into mouths and on hands. Try to limit contact with remotes and definitely don't let them become toys! We like to keep them out of reach on a shelf.

Cell Phones

It seems like all babies become obsessed with cell phones... probably because they see us constantly looking at them! But is it safe to let your baby chew or mouth your phone? Definitely not. Cell phones are covered in germs, including some pretty nasty pathogens like E. Coli (3). They also contain a lot of chemicals and substances, like batteries, heavy metals, flame retardants, and plasticizers, which are all toxic. Plus, if your baby is teething or has teeth, they could chip the phone and little pieces could come off that can be a choking hazard. Because of all these hazards, teething babies and cell phones are not a good match. But if your child is old enough to play games on your phone, wash their (and your!) hands after they use it, especially before snacks and meals.

Jewelry

Jewelry is sparkly, shiny, and colorful, which basically just screams "please put me in your mouth!" to babies. Unfortunately, metal jewelry can contain toxic heavy metals like lead and cadmium while plastic jewelry can contain bisphenols or plasticizers. Lead is a dangerous neurotoxin at any dose, and cadmium can cause kidney, bone, and lung damage. Brass is also a common component in jewelry, which can contain up to 3% lead. And just because it's expensive doesn't mean it's safer; jewelry at all sorts of price points have been found to contain these heavy metals. Research has found that the amount of heavy metals that get ingested while chewing or mouthing jewelry can be dangerous (4). Even jewelry that seems completely harmless, like Mardi Gras beads, has been found to contain toxic substances. So let jewelry be just something nice to look at and let kids chew on a set of silicone teething beads instead.

Sunglasses

Sunglasses come in all sorts of sizes and shapes nowadays, but most sunglasses are made of a polycarbonate plastic that contains BPA. While it may not be a big exposure risk for adults who wear them, letting your little one chew on them or suck the ends is not the best idea. BPA is a hormone disruptor and kids are especially vulnerable as they are in a sensitive growth period. Yet another reason to always pack a safe teether in your bag if your little one is an especially mouthy one!

Non-Toxic Candle Roundup

They smell even better than they look! Plus no harmful chemicals

Trying to set the perfect mood for Valentine's Day? We've got you covered! Our candle roundup is a great guide to finding the perfect candle. Most candles contain paraffin wax, which is made from petroleum and use fragrance oil. And fragrance can contain a ton of harmful chemicals. Our candles only use natural wax like soy or beeswax, and only contain essential oils! Plus they all smell amazing!



a) Aira Soy Candles
b) Lulu Candles Natura 100% Organic Soy Vegan Wax Candle
c) Big Dipper Beeswax Aromatherapy candle
d) Milk + Honey essential oil candle
e) Pure Plant Home glass candle
f) Edens Garden essential oil candles

Wondering why you need a non-toxic candle? Candles release compounds known as volatile organic compounds whether they are lit or not (1). VOCs can have both short and long term adverse health effects and there are consistently higher concentrations of VOCs indoors than outdoors. The majority of the VOCs released from candles is because they doesn't burn cleanly, which releases acetaldehyde, formaldehyde, acrolein, phenol, benzene, and toluene, many of which are carcinogenic (3). Phenols (one of the words in that list if you jumped to the end of the sentence when you started seeing a bunch of scary words) are the fragrance chemicals that make candles smell like brown sugar, wild mango, and clean laundry. It makes sense that it would take some pretty weird chemicals to bottle up the smell of a tropical island in a single candle, right?

It's definitely healthier and safer to go with candles scented with essential oils to avoid some of these nasty VOCs. A few of the other VOCs released can cause changes to our DNA (and in some cases, bad changes!). Of all of the VOCs released, formaldehyde and acrolein are the other two biggest worries because they are released in the highest concentrations. Formaldehyde itself can cause cancer (4) while acrolein, which is used to make weapons in high concentrations, can kill you if you breathe in too much of it - Yikes (5). I don't know about you, but those are some things I definitely don't want to invite to my relaxing spa night!

Candles are also traditionally and most commonly made of paraffin, which is obtained from petroleum or shale. We recommend candles made from beeswax or soy because they come from natural sources. Some candles wicks may contain lead, so always make sure to look for a "lead-free" wick made from cotton.
