People are dumbfounded when they learn this little known secret to burning candles correctly

There's an art to avoiding the "memory ring" that makes a candle tunnel around the wick.

The "tunnel" that often forms around a wick isn't supposed to be there.

The evolution of candles from lighting necessity to scented ambience creator is kind of funny. For thousands of years, people relied on candles and oil lamps for light, but with the invention of the light bulb in 1879, fire was no longer needed for light. At that time, people were probably relieved to not have to set something on fire every time they wanted to see in the dark, and now here we are spending tons of money to do it just for funsies.

We love lighting candles for coziness and romance, relishing their warm, soft light as we shrink from the fluorescent bulb craze of the early 2000s. Many people use candles for adding scent to a room, and there are entire candle companies just for this purpose (Yankee Candles, anyone?). As of 2022, candles were an $11 billion business. Michael Scott once said they're the number one fastest growing product in the scent aroma market.

With their widespread use, you'd think we'd know a thing or two about candles, but as it turns out, a whole bunch of us have been burning candles wrong our entire lives without knowing it.

A recent post on Twitter X started the education session:

"Just learned that my fiancé, who buys candles all the time and we literally always have candles burning, did not actually know how they work and blew out a medium first burn candle 30 minutes after I lit it when I wasn’t paying attention and ruined it," the user wrote.

Many people had no idea what she was talking about. In fact, the original since-deleted post went viral with hundreds of people asking: Huh? So the OP explained.

"If a candle is not burned for long enough on first burn to melt edge to edge it will create a 'memory ring.' Once a candle has a memory ring, it will continue to tunnel and never burn all the way across."

Now THAT'S something almost everyone has experienced. Candles are pretty expensive, so it's frustrating when all that delicious-smelling wax gets left behind. Apparently, a short first burn (in this case, just 30 minutes) is one of the main culprits of a ruined candle.

Tunneling is the name of the phenomenon where a narrow tube-shaped area of candle continues to burn deeper and deeper, leaving lots of "waste" wax around its edges. Experts agree that the first burn should last 2-4 hours at least to avoid an uneven or narrow memory ring. (But don't burn a candle for over 10 hours at a time or you risk too much carbon buildup on your wicks.)

"If a candle is not burned for long enough on first burn to melt edge to edge it will create a 'memory ring.' Once a candle has a memory ring, it will continue to tunnel and never burn all the way across."

"This is why you should not light a large candle at night, which is unlikely to burn all the way across before you need to blow out to go to bed. Allow at least one hour per inch of candle width," she went on.

So that's why candles always end up with a hole in the middle, making us think the candle companies are just running a scam to make us go through candles faster. Nope. It's user error, and many people were flabbergasted by this realization.

"This is the most useful information I’ve been given my entire adult life," wrote one person.

"This skill should be taught in schools," shared another. "The amount I’ve wasted on half burnt candles is outrageous, the amount of times I’ve used Algebra since leaving school = 0."

"When I worked at Pier 1 in the 90s I got to go to some candle workshop that taught us the correct way to use (and therefore sell) candles and that is probably some of the most useful knowledge I've carried in my head this long life," shared another.

Well, never say 'never,' because here's the good news: a tunneled candle can be fixed!

Probably the easiest way is to avoid tunneling your candles in the first place by burning them long enough upon first burn to liquify the entire top layer of wax. Again, that's usually 2-4 hours.

It also helps to care for the wicks regularly! Good wicks allow for a clean, even burn. Trim the burnt ends before lighting the candle and, if possible, use a snuffer instead of blowing out the flames with your mouth. Using a candle warmer is another way to get an even melt; with the added perk of making the scented wax last much, much longer.

But even if you do accidentally "ruin" a candle, it can be recovered. Placing a ring of foil around the candle with just a small opening at the top for the flame will help trap heat and help the edges of the wax melt on the next burn. Once the memory ring evens out, you can burn the candle like normal again.

(In fact, you can even use a candle warmer to melt the wax back to even and then resume burning. Some clever candlers even put candles on the hot pad of their coffee makers as a DIY hack.)

The candle posts also prompted a separate discussion about candles and indoor air quality and the volatile organic compounds that are released when they are burned.

Some people equated burning candles with having a small engine running in your living room, though according to the Cleveland Clinic, there's scant evidence that the amount of toxins released by burning candles is actually hazardous to your health, especially if you use high quality candles in a well-ventilated area.

How do you know if a candle is "high quality"? First, check the wick for metal. Lead in wicks is not nearly as common as it used to be, but best not to risk it if you find metal in the wick. Second, choose soy, beeswax, palm or coconut wax candles instead of paraffin, which is petroleum-based product and more likely to put off soot and smoke particles. Everyone reacts differently to different amounts of particulates in the air, so if you find yourself getting headaches or respiratory symptoms when using candles, it's probably best to avoid them.

But if you tolerate them, feel free to enjoy as recommended,—just make sure that first burn melts the wax all the way to the edges to avoid the dreaded tunneling.

A juice company dumped orange peels in a national park. This is what it looks like today.

12,000 tons of food waste and 28 years later, this forest looks totally different.

A before and after view of the experiment

In 1997, ecologists Daniel Janzen and Winnie Hallwachs approached an orange juice company in Costa Rica with an off-the-wall idea. In exchange for donating a portion of unspoiled, forested land to the Área de Conservación Guanacaste — a nature preserve in the country's northwest — the park would allow the company to dump its discarded orange peels and pulp, free of charge, in a heavily grazed, largely deforested area nearby.

One year later, one thousand trucks poured into the national park, offloading over 12,000 metric tons of sticky, mealy, orange compost onto the worn-out plot. The site was left untouched and largely unexamined for over a decade. A sign was placed to ensure future researchers could locate and study it.

16 years later, Janzen dispatched graduate student Timothy Treuer to look for the site where the food waste was dumped.

Treuer initially set out to locate the large placard that marked the plot — and failed.

"It's a huge sign, bright yellow lettering. We should have been able to see it," Treuer says. After wandering around for half an hour with no luck, he consulted Janzen, who gave him more detailed instructions on how to find the plot.

When he returned a week later and confirmed he was in the right place, Treuer was floored. Compared to the adjacent barren former pastureland, the site of the food waste deposit was "like night and day."

"It was just hard to believe that the only difference between the two areas was a bunch of orange peels. They look like completely different ecosystems," he explains.

The area was so thick with vegetation he still could not find the sign.

Treuer and a team of researchers from Princeton University studied the site over the course of the following three years.

The results, published in the journal "Restoration Ecology," highlight just how completely the discarded fruit parts assisted the area's turnaround.

According to the Princeton School of International Public Affairs, the experiment resulted in a "176 percent increase in aboveground biomass — or the wood in the trees — within the 3-hectare area (7 acres) studied."

The ecologists measured various qualities of the site against an area of former pastureland immediately across the access road used to dump the orange peels two decades prior. Compared to the adjacent plot, which was dominated by a single species of tree, the site of the orange peel deposit featured two dozen species of vegetation, most thriving.

In addition to greater biodiversity, richer soil, and a better-developed canopy, researchers discovered a tayra (a dog-sized weasel) and a giant fig tree three feet in diameter, on the plot.

"You could have had 20 people climbing in that tree at once and it would have supported the weight no problem," says Jon Choi, co-author of the paper, who conducted much of the soil analysis. "That thing was massive."

Recent evidence suggests that secondary tropical forests — those that grow after the original inhabitants are torn down — are essential to helping slow climate change.

In a 2016 study published in Nature, researchers found that such forests absorb and store atmospheric carbon at roughly 11 times the rate of old-growth forests.

Treuer believes better management of discarded produce — like orange peels — could be key to helping these forests regrow.

In many parts of the world, rates of deforestation are increasing dramatically, sapping local soil of much-needed nutrients and, with them, the ability of ecosystems to restore themselves.

Meanwhile, much of the world is awash in nutrient-rich food waste. In the United States, up to half of all produce in the United States is discarded. Most currently ends up in landfills.

"We don't want companies to go out there will-nilly just dumping their waste all over the place, but if it's scientifically driven and restorationists are involved in addition to companies, this is something I think has really high potential," Treuer says.

The next step, he believes, is to examine whether other ecosystems — dry forests, cloud forests, tropical savannas — react the same way to similar deposits.

Two years after his initial survey, Treuer returned to once again try to locate the sign marking the site.

Since his first scouting mission in 2013, Treuer had visited the plot more than 15 times. Choi had visited more than 50. Neither had spotted the original sign.

In 2015, when Treuer, with the help of the paper's senior author, David Wilcove, and Princeton Professor Rob Pringle, finally found it under a thicket of vines, the scope of the area's transformation became truly clear.

"It's a big honking sign," Choi emphasizes.

19 years of waiting with crossed fingers had buried it, thanks to two scientists, a flash of inspiration, and the rind of an unassuming fruit.

Newlyweds land paid job living for free on gorgeous, uninhibited Irish island

They beat out 80,000 other applicants for the job of a lifetime.

Camille Rosenfeld; Alice Hayes

It's their dream of a lifetime.

What’s your dream job? President of the United States? A famous influencer with millions of followers and brand partnerships? A former NBA player who now cruises the airwaves with his besties, à la Charles Barkley? No? Well, what about this: Moving to a remote, uninhabited island in Ireland where there’s no running water, no hot showers, and no electricity? Sound enticing?

While that may not exactly sound like “heaven” to most folks, for newlywed couple Camille Rosenfeld (26) from Minnesota and James Hayes (37) from Tralee, Ireland, this version of the island life is exactly what they signed up for. From April 1 to September 30, the newlywed couple will become the caretakers of Great Blasket Island, a remote and uninhabited island off Ireland’s coast in the Atlantic Ocean.

Once there, they’ll be trading modern conveniences for candlelight and the constant company of seagulls—an existence not terribly dissimilar from the one depicted in Robert Eggers’ 2019 movie, The Lighthouse—and the couple couldn’t be more delighted.

“Oh my gosh…it seems like such a dream come true,” Rosenfeld gushed to CBC Radio. “You wouldn't even think it would be a possibility. We feel really lucky that we were chosen.”

But make no mistake: this is not a vacation. Like Jack Torrance in The Shining, Rosenfeld and Hayes will become Great Blasket’s live-in caretakers, tasked with attending to the principal island of the Blaskets in County Kerry, Ireland. They will live in a small stone house on a windswept hill overlooking the gray, stormy seas at night. By day, they will run five holiday cottages and a coffee hatch for day-trippers visiting the island. “I genuinely think we will fall in with the rhythm of our new life and sense of freedom,” said Hayes, who has been to the island once before. “We won’t have the responsibilities of our jobs or day-to-day life, so it’s a chance to live a simpler life.”

 

“It looks like something from The Wizard of Oz”

 

Located about a mile off the Dingle Peninsula in County Kerry, Great Basket Island— or in Irish, An Blascaod Mór—is a place of stunning natural beauty, where emerald hills glisten and below the cliffs lie sparkling turquoise waters. “It’s just so green, the greenest grass you’d ever see,” Rosenfeld said. “During a few weeks in the summer, there’s these beautiful purple flowers that bloom all across the fields. It looks like something from The Wizard of Oz.”

Once a flourishing fishing and farming outpost, Great Blasket Island was previously home to a tight-knit Irish community. For centuries, residents ate wildly caught fish and rabbits and harvested potatoes. In its heyday, the island nurtured a vibrant literary culture, with voices like Peig Sayers, Tomás Ó Criomhthain, and Muiris Ó Súilleabháin immortalizing the raw beauty and hardship of life there. However, by 1953, the island’s remaining inhabitants were forced to evacuate due to dwindling numbers and the lack of emergency services there during storms. Now, the island is a living museum of Gaelic heritage and a place where wildlife thrives.

While the island may not have many humans these days, Great Blasket Island is home to a great number of marine life: Gray seals (also known as “horseheads”) are the island’s star attraction, with their short flippers and hidden ears (gray seals lack ear flaps). During the late spring, thousands of gray seals come to Great Blasket to congregate, where they can be spotted among sharks, dolphins, whales, and seabirds. “We have no fears of anything around island life, not even the large number of seals that make their home on the beaches there,” the couple said. “We will deal with any issues as they come along.”

 

Landing the job

 

Billy O’Connor and his wife, Alice Hayes (no relation to James), who own the small collection of holiday cottages Camille and James will soon oversee, first advertised the live-in position in 2020. Initially, they were awash with over 80,000 applicants. Now, for their own sake, they’ve capped the number of applications to a mere 300. To deter hopefuls looking for a pleasant holiday, Billy and Alice try to stress the grueling nature of the job: “First, we try to put them off because if anything, it is quite romanticized,” says Alice. “But during the season, it can be quite intense for the caretakers. Most people, when they finish work, go home to their safe haven and relax. But I often say to people going out there that they won’t have that. You close the half-door where you were serving coffee, and you are home.”

Camille and James, on the other hand, are excited to trade a life in the fast lane for one that's much simpler. The two met in 2021 at the Burren College of Art, where Hayes was in residency as a visual artist, and Rosenfeld was studying abroad at the Rochester Institute of Technology, where she studied art and business. They’d actually applied for the caretaker position the year before, but the timing didn't work out because of their scheduled wedding.

When they reapplied the following year, Alice and Billy were ecstatic. "When we saw that Camille and James had applied again for the positions for this year, we were delighted as they are just so enthusiastic and committed to outdoor life," says Alice.

 

Stewardship: A growing interest in Europe

 

Besides being an excellent adventure for a newlywed couple, this hands-on approach to land stewardship is part of a growing trend in Europe. Land stewardship is increasingly being recognized as a practical and rewarding tool for nature and biodiversity conservation, often found at the intersection of environmental protection and sustainable economic practices. In the United Kingdom, for example, such land trusts play a significant role in managing protected areas and sites of natural importance. Ahead of their new jobs, Camille and James reflect on the part they’ll play in this larger context. "I think both Camille and I feel that we have been living our lives on aeroplanes travelling over and back to the US and out of suitcases with no set familiarity to our lives over the past three years and longer," James explains. Camille adds: "It will provide the time to take stock, immerse ourselves in island life and start the next chapter or new book of living our lives together in one place.”

People are baffled to find out they've been burning candles wrong their whole lives

Some people suggested wrapping aluminum foil around the rim of the candle to help recover a candle that's been tunneled or to speed the process of melting the wax across the entire candle. Other suggested melting the candle down in the oven to even it back out again. The original poster pointed out that sometimes candles aren't wicked properly. According to Lone Star Candle Supply, if a candle is more than 4 inches in diameter it may become necessary to have two wicks.

The candle posts also prompted a separate discussion about candles and indoor air quality and the volatile organic compounds that are released when they are burned.
