“The presence of hazardous elements in both the paint and glaze of decorated glassware has obvious implications for both human health and the environment. So it was a real surprise to find such high levels of lead and cadmium, both on the outside of the glassware and around the rim,” said study leader Andrew Turner.
“I would imagine the U.S. would have a similar problem, especially when many products are imported from Asia,” Turner added. Cadmium can cause cancer, and studies have also linked it to bone softening and severe kidney problems.
Some tests carried out by the researchers revealed lead levels 1,000 times higher than the acceptable limit, Turner's group said. “There are genuine health risks posed through ingesting such levels of the substances over a prolonged period, so this is clearly an issue that the international glassware industry needs to take action on as a matter of urgency,” Turner added in a university news release.
Last year, McDonald's recalled 12 million Shrek-themed glasses because the painted designs contained cadmium, the researchers said. Given that safer alternatives are available to the industry, Turner said the continued use of dangerous pigments is both surprising and concerning.
“Why are harmful or restricted elements still being employed so commonly to decorate contemporary glassware manufactured in China, the European Union and elsewhere?” “Consumers should be made aware of this, while retailers and the glass industry have the responsibility to eliminate toxic metals from decorated products,” he added.
Then she got a new computer at work, with a much brighter screen, and her eyes and head started hurting. Settler is among the growing number of people who wear special eyewear to block or filter the high-energy blue light coming from digital screens.
The e advertised benefits of the glasses include less eyestrain, improved sleep habits, and prevention of eye disease. The American Academy of Ophthalmology says you don’t need them and has gone on record as not recommending any kind of special eyewear for computer users.
Greg Rogers, senior optician at Eye works in Decatur, GA, says he’s seen the benefits of blue light glasses among the shop’s customers. The staff asks a client how much time they spend in front of a screen daily.
If it’s 6 hours or more, some sort of blue light reduction technique is recommended, whether it’s glasses or a special screen for a computer monitor. The Vision Council, which represents the optical industry, says “specialized glasses” are “one tactic” that might cut eyestrain.
Samuel Pierce, OD, former president of the American Optometry Association, told USA Today he recommended using blue light glasses to lessen eyestrain. But gadgets like televisions, smartphones, laptops, and tablets that populate modern life emit the brighter, shorter-wavelength (more bluish) light.
A 2018 survey by Acuvue, the contact lens maker, found office workers spend about 6.5 hours a day sitting in front of their computer. A Pew Research Center survey found that 28% of American adults say they go online “almost constantly,” up from 21% in 2015.
Susan Prime, OD, an optometrist and professor of ophthalmology at Emory University, agrees that the research so far shows digital overuse, not blue light, causes eye problems. Prime says she’s bothered by some marketing and advertising of blue light eyewear because it doesn’t line up with the research.
An example: A chain of stores in the United Kingdom, Boots Ltd., was fined 40,000 pounds in 2017 for misleading advertising that said digital blue light caused retinal damage and that special eyewear sold at Boots Ltd. could protect users, Optometry Today reported. Researchers agree that blue light from LED devices like your smartphone or laptop holds back the body’s production of sleep-inducing melatonin.
A 2017 study done by the University of Houston found that participants wearing the glasses showed about a 58% increase in their nighttime melatonin levels. “You don’t need to spend extra money on blue light glasses to improve sleep -- simply decrease evening screen time and set devices to night mode,” the group says.
Cindy Colbert of Atlanta had a variety of vision problems and spent an extra $140 at the eye doctor for blue light lens. Michael Clarke of San Diego says he doesn’t care what the experts say about blue light glasses.
You can easily order prescription and nonprescription blue light glasses at the optometrist’s office or online. Calls to optometry offices showed that adding blue light blocking to prescription glasses cost $40-$60 at LensCrafters and $47-$125 at Pearl Vision, with nonprescription blue light glasses starting around $99.
If you’re worried about how computers and other blue light-emitting screens are affecting your eyes, you can find relief without special eyewear. The American Academy of Ophthalmology, the Vision Council, and other vision-related organizations urge moderation in screen use.

Plastic glasses, which are lightweight and less prone to shattering, have started gaining popularity. Clear glasses are great for seeing what you’re drinking, but that doesn’t mean they have to lack color completely.
The weighted bottoms help keep the glasses stable and make them feel substantial in the hand. Ripples on the bottom of the glass help manage the sweating that occurs with a cold beverage hot day.
For anyone who wants a design classic for their drinking glass, this Pi cardie tumbler from Durable is the clear winner. Durable is a French company that pioneered tempered glass, so you know that this tumbler not only has beautiful vintage-inspired styling, but is also incredibly sturdy.
(Which means you might want to order two sets if you know you’ll need eight drinking glasses at any point.) While you might expect plastic for this price point, these are made of high quality glass and come with a raised polka dot pattern.
The glasses are also stackable to save on cabinet space and dishwasher safe to make post-dinner cleanup even easier. For those who are willing to spend a bit more on their glassware, this set of four drinking glasses from Libya, is an easy choice.
The heavy, weighted bottoms make for sturdy glasses that won't knock over easily while also providing a more refined aesthetic. The glasses are also on the larger side, holding a full 18 ounces of your favorite beverage.
You can feel good about your purchase knowing that all of Libya's glassware is made in the USA. Whether you like to dine on a patio or porch, or just have a tendency to break your glasses easily, plastic can be a good solution.
The fan favorite, Serves hosts your drinks in a 16 ounce tumbler while also keeping liquids cool (or hot) and the outside sweat-free. You can order a plain set or get more creative with some of their personalized or more holiday oriented motifs.
To help you find what you’re looking for, we’ve categorized their picks by style and size. It’s easy to see why: They are available in assorted sizes, so you’ll always have the right one at hand if someone wants water, juice, or a stiffer drink.
More important, as Tracie Battle, a senior designer at online interior-design service Heavenly, says, their “classic look will never go out of style.” She explains that they are made of thicker tempered glass, which “offers more durability and a more expensive look.” Hudson Wilder founder Conway Lao and author (and former Lucky Peach executive editor) Rachel Kong also swear by these glasses, with Kong saying that her set is “still going strong after many years.” This 18-piece set includes three sizes and six glasses in each size. Battle also recommends Libya’s Polaris glasses for their “super-unique shape,” which includes a rounded, weighted base that feels hefty while still being sleek.
The Bodega is also a favorite style of Julie Mulligan, the owner and designer of cocktail lounge and restaurant Lot 15, because it’s “versatile and low maintenance but still chic.” She says that it’s “great for all kinds of home drinking and serving” and can even be used for displaying flowers. Both Lao and Amanda Spin, the general manager of Williamsburg’s Four Horsemen restaurant and Night moves bar, swear by these shorter, stackable glasses by Japanese company Toyo-Sasaki.
Intended for the service industry, these glasses come in a case of 72, which is more than an average household will ever need. Paul Malone, a co-founder of Boston Burger Company, says the style is better for stacking.
For your everyday drinking and mealtime beverages, you may want something casual or something fancy. Choosing a glassware set may seem pretty straightforward, but there are quite a few features you should consider.
At Bestrews, our aim is to put an end to your shopping dilemmas. If you’d like to know a bit more about glassware before making a decision, continue reading this guide.
While it’s often used for cocktails, it works well for everyday beverages like water and soda, too. A cooler glass has a tall, narrow body and typically holds 12 to 14 ounces.
It’s ideal for most beverages, including water, soft drinks, iced tea, and lemonade. It typically holds five to seven ounces, and it also works well for milk or other beverages which you don’t necessarily want to drink in large quantities.
However, it’s best to avoid sets that contain only juice glasses because they’re smaller and not the most versatile option. Some glassware sets feature embellished designs that make them more decorative.
The glass may be tinted all over or feature colored bands for a fun look. The glass has a silver or gold band along the rim for an elegant look.
The glass is textured in some type of pattern, such as a pebbled or bubble design. For the most durable glassware, choose a set made of tempered glass.
During its manufacture, tempered glass is heated and then cooled quickly. A tempered glassware set can be used for both cold and hot beverages.
Few people enjoy doing the dishes, so you probably want a glassware set that’s easy to clean. The size that works best for your kitchen depends on the number of people in your household and how often you entertain.
If you frequently entertain large groups, a 24-glass set can help accommodate all of your guests. For most households, 12 everyday drinking glasses is a good number.
Glassware set price tags run the gamut from $10 to $70. Cost varies based on several factors, including the number of glasses in the set and the quality of the materials and design.
Even if your set is dishwasher-safe, it’s a good idea to use the delicate wash cycle to protect the glass. Space the glasses carefully on the rack, so they don’t clink against one another during the cycle.
Use a sponge or soft foam brush when washing your glasses. Avoid storing glassware in a cabinet that’s prone to humidity or extreme temperatures.
Can I use a glassware set for both cold and hot beverages? If you want to use your glassware for both hot drinks and cold beverages, choose a set that is specifically designated as heat-resistant, so it can withstand higher temperatures.
For older children who you can trust with drinking glasses instead of plastic cups, it’s best to exercise caution. To keep these glasses particularly sparkly, Scott Wiesel uses Titan Crystal, which has both titanium and zirconium for added durability and clarity.
All-purpose glasses, Mazama tells Prevention.com, are tulip-shaped with a “wide bowl to allow for more aeration, pulling out more subtle flavors, and focusing those nuances directly to the wine drinker’s nose and palate.” This is a somewhat smaller all-purpose glass, so stick with the whites and roses here, but a larger version will serve your reds well. For a (somewhat) more affordable Bordeaux wine glass compared to #9 below, designed with Merlot and Avignon varietals in mind, we choose Raided, whose classic Venue wine glass was first introduced over three decades ago.
This allows the aromas to be quickly delivered to the drinker,” which makes them ideal for darker colored wines with more oak and higher alcohol content. With a 12.9 oz capacity, this more delicate piece of stemware has a beautifully long stem that looks effortlessly chic in any place setting.
These glasses are also relatively inexpensive, and like the rest of Raided’s lineup, beautifully made without being overly delicate. If you’re looking for an elegant and affordable stemless option, the Rascal Harmony lineup is an excellent place to start.
The bold, edgy, and decidedly angular design is handcrafted with Titan crystal (scratch and chip-resistant) in Germany, and looks right at home both at your fanciest dinner party and at a casual (boozy) breakfast. Gracioushome.comic you’re looking for wine glasses to gift (either as the gifted or the receiver), the Richard Brendon and Janis Robinson collaboration that gave way to these beautiful all-purpose pieces of stemware are bound to impress.
Made to be truly all-purpose (the glassmakers note that these pieces are varietal-agnostic), the glasses are incredibly lightweight and thin, both in terms of the stem and the thickness of the bowl itself. The rounded glass looks more classic than the sharply angled modern varietals, and offers a timeless elegance and drink ability.
Surprisingly, these glasses are dishwasher safe, though they’re so beautiful that you may not feel comfortable sticking them in your machine. This content is created and maintained by a third party, and imported onto this page to help users provide their email addresses.
Ian Cable, one of just 202 Master Smelters in the world and one of the experts behind the SommSelect team, notes, “The glass a person chooses will have a major impact on their overall wine experience.” In much the same way that you wouldn’t dream of listening to your favorite album from a static-y radio station, Cable told us, you lose part of the experience when drinking great wine from a less-than-great glass. “If you are investing your money in good bottles of wine, stemware should not be overlooked,” Cable added.
“The delicate aromas in wine volatile (from liquid to gas) when you swirl the glass, and those molecules hit our olfactory bulb (smell receptor) which then sends those messages to our brain.” Red wine glasses are, generally speaking, a bit larger, both in terms of height and circumference.
Largely because red wines tend to be more assertive in flavor and aroma, which means that a larger glass is better-suited to capturing and releasing those fantastic smells. And then, of course, there’s the ongoing stemmed versus stemless debate; Montgomery and Resume note that deciding between the two is largely a personal preference.
“At the end of the day, it's a personal preference but if you're trying to keep your rose chilled, we'd suggest using glassware with a stem.” In fact, Rutherford noted, the Bordeaux glass can be used for both red or white wines (though their sizes will differ).
And though you could certainly spend hundreds of dollars on your stemware, not all great wine glasses cost a small fortune. Common types of glassware include beakers, flasks, pipettes, and test tubes.
Magi Studio / Getty Images Beakers are the workhorse glassware of any chemistry lab. The spout makes it easy to pour liquids into other containers.
Finally, the wide opening makes it easy to add materials to the beaker. Bogdan Drama / Eye / Getty Images There are multiple types of flasks.
For some situations, either a beaker or an Erlenmeyer flask is a good choice, but if you need to seal a container, it's much easier to put a stopper in an Erlenmeyer flask or cover it with para film than it is to cover a beaker. Stuart Money / Getty Images Test tubes are good for collecting and holding small samples.
Thanakorn Srabubpha / Eye / Getty Images Pipettes are used to deliver small volumes of liquids reliably and repeatedly. This type of glassware isn't intended to be exposed to flames or extreme temperatures.
Pipettes can be deformed by heat and lose their measurement accuracy under extreme temperatures. It's almost always made of borosilicate glass so that it can withstand heating under a direct flame.
ElementalImaging / Getty Images Volumetric flasks are used to prepare solutions. Each features a narrow neck with a marking, usually for a single precise volume.
Because temperature changes cause materials, including glass, to expand or shrink, volumetric flasks aren't meant for heating. These flasks can be stoppered or sealed so that evaporation won't change the concentration of a stored solution.
But those made of glass are more common due to time tested use and suitable for all the experiments. The glass beaker has readings on the surface to indicate volume levels in the container.
a) To store liquids like solvents, solutions, reagent mixtures, oils, etc. Measuring cylinder: It is similar to a beaker but has a very little diameter and more height.
It is widely used to take a desired volume of liquid into a beaker. To make up the final volume of mixtures by small additions using a pipette.
This is a conical shaped glass apparatus with a round bottom. Conical flask does not contain graduated readings in most cases.
Since the mixture requires constant stirring, the sample is taken in a conical flask and the reactive agent is added from the burette drop by drop till with constant swirling of the flask and its contents till the endpoint. Since the mouth is narrow, the fumes of reaction can be made to escape safely without exposing the lab interiors.
Test tubes are mostly non-graduated as one can just add the desired volume from a pipette or burette. They are also required in large numbers as small amounts of reagents can be taken at a time.
For heating reactions by taking a small quantity of mixtures using a test tube holder. For the distillation of solutions, wherein the substance is taken in the flask and heated from the bottom.
The volumetric flasks are round at the bottom with a long narrow neck. Uses: This flask is especially needed for filtration and crystallization of extracts in the chemistry lab.
In lab often one needs transparent funnels to pour solvents, powders and other liquids into other containers. These funnels are very useful as they minimize the chances of waste due to spillage.
Uses: This helps in the safe transfer of liquids and also prevents spillage and wastage. It can hold liquid without leaks when closed with a stopper on top.
The vent at the bottom of the flask can be opened and individual solvents can be drained out. Uses: This is useful for the separation of substances from a mixture based on their polarity or solubility.
Ex: Lipids can be separated from an aqueous extract by using petroleum ether. Burette : It is a long cylindrical-shaped glass tube with a stopper at one end.
This burette has uniform diameter all along the length with clearly marked graduation indicating of volume. A burette needs a stand to hold it in place as shown in the image below.
