Borosilicate glass might sound like something out of a science lab but you probably have something made of it sitting in your kitchen right now. It's commonly used by some of the biggest names in kitchenware for its non-toxic composition and durable design. But what exactly is borosilicate glass and how is it used?
If you want to learn more, please visit our website why is glass resistant to acid.
Borosilicate glass is made by melting sand with boron trioxide to limit the material's ability to expand when exposed to heat. This makes it the ideal material for making glass cookware, containers, and even scientific tools. You've likely used it before without even realizing it.
In this overview, we'll explain everything you need to know about borosilicate glass. Get ready to learn how it's made, what sets it apart from standard glass, where you've likely seen it before, and how safe it is for your family and friends.
What is Borosilicate Glass?
Borosilicate glass is a special type of glass made by mixing 70-80% silica sand with boron trioxide. At first glance, you likely wouldn't be able to tell the two-component materials apart but, when heated, boron trioxide absorbs massive amounts of heat before crystallizing into a glass. Once the two fuses into the glass, boron trioxide slows the annealing process, producing a harder, more durable material.
Thanks to its ability to absorb such high temperatures, boron trioxide also makes the glass less susceptible to thermal exposure, thus guaranteeing that the final product can withstand a lot of heat without melting, warping, or cracking. For this reason, borosilicate glass is a popular choice for chefs and scientists alike.
What is Borosilicate Glass Used For?
Just about everyone who's gone through the public school system has used borosilicate glass at least once in their life. Since it's able to withstand incredibly high temperatures without melting or cracking, borosilicate glass is the material de jour for making scientific equipment such as test tubes, beakers, and stirring rods. If you've ever heated a beaker over a Bunsen burner, you've used borosilicate glass.
What is the Difference Between Regular Glass and Borosilicate Glass?
Besides the added boron trioxides, borosilicate glass stands out from regular glass for a few important reasons:
1) Durability ' First and foremost, borosilicate glass is more durable than standard glass. Most objects made from borosilicate glass can survive a knock or two without chipping, cracking, or shattering.
2) Heat Resistance ' As we've mentioned above, borosilicate glass is prized for its ability to withstand incredibly high temperatures without cracking or melting.
3) Stability ' Borosilicate glass is highly stable, meaning it won't leach chemicals or toxins. In fact, it's so stable that it's used in nuclear reactors to transport nuclear waste without leaching radiation.
Of course, just looking at it, you might not be able to tell the difference between borosilicate glass and regular glass. In the next section, we'll spill the beans and fill you in on how to tell the difference.
How Can You Tell if Glass is Borosilicate?
Before we explain exactly how to tell the two apart, we need to get a little more specific. Most glass kitchenware is made from one of two materials'soda-lime glass or borosilicate glass. Soda-lime glass is made from a combination of silica sand, sodium oxide, and calcium oxide. It's able to withstand high temperatures but at a lower coefficient than borosilicate glass.
If you're unsure which material your glass kitchenware is made from, you can try eyeballing it to make a rough estimation. Take a close look at the edge of your baking dish, container, or bowl and try to find a bluish-green tinge. If it's there, you've got soda-lime glass. If not, you've got borosilicate glass. However, this test isn't exactly accurate.
If you want to know which material you've got, you'll have to contact your nearest scientist. They can heat the material to extreme temperatures, scratch it with diamonds, or use a special optical lens to gauge which type of glass you have. If this sounds like too much effort, there's one other option.
Simply check with the manufacturer! All glass kitchenware brands should publicly disclose which type of glass they used to manufacture their products. If it's not easily available on the object itself, check the company's website or send them an to enquire.
Is Borosilicate Glass Safe for Health?
Remember when we said that borosilicate glass is made from boron trioxide?
In its raw form, boron is unsafe for human or animal consumption. It's such a powerful toxin that it's commonly used as a pesticide. In dry seasons, it sometimes washes into drinking water supplies, leading to widespread boron poisoning. So, if it's so dangerous, why are we making glass from boron?
The trick is to bind boron with silica glass. When boron trioxide is melted and fused with silica sands, it becomes inert and highly stable. Even if exposed to chemical reactants, the boron cannot escape its glassy prison, keeping you safe from its toxicity. It's so stable that borosilicate glass is even used in nuclear reactors to prevent radiation from leaching from waste.
Is Borosilicate Glass Safe in the Kitchen?
The boron in borosilicate glass is safe because it stays trapped inside the glass.
Remember, borosilicate glass can withstand incredibly high temperatures. It has a melting point of around 3,000 degrees Fahrenheit. Unless you currently own a smelting furnace, you're unlikely to ever reach those temperatures in your home kitchen. Therefore, you can safely cook with borosilicate glass.
Is Borosilicate Glass More Durable?
Compared to standard glass, borosilicate glass is definitely more durable. Thanks to the addition of boron trioxide, the material takes a long time to cool during the manufacturing process. Slower cooling helps harden the glass and prevents it from becoming brittle. Once it finally cools into a baking dish or storage container, it's strong enough to survive a trip through the dishwasher or a few bumps and drops.
That being said, there are a few things you should avoid doing to your borosilicate glass cookware:
' Sudden temperature changes ' Avoid shocking borosilicate glass with sudden and drastic temperature changes. Moving borosilicate glass directly from a freezer into an oven can shock the material and cause it to crack.
' High drops ' Just because it can survive a few bumps and knocks without cracking or chipping doesn't mean you can drop a borosilicate dish from the top of your counter onto a hard stone floor.
' Physical trauma ' Borosilicate glass is still glass. Don't think that just because it's more durable it can stand up to a hefty smack. It will break if you throw it or hit it with something hard or heavy.
As long as you use your borosilicate glass kitchenware as it's intended, you shouldn't have to worry about it breaking. It's oven, microwave, and dishwasher safe and can withstand everyday bumps and knocks.
Is Borosilicate Glass Better for the Environment?
Stop to consider your daily habits. Do you buy a plastic water bottle every day? Do you use plastic containers at home? If so, you're actively contributing to the ongoing plastic crisis affecting the world's oceans and waste management systems. Every year, it's estimated that 91% of the world's plastic production goes unrecycled, left to be thrown in landfills and onto garbage barges.
Switching to borosilicate glass can help reduce your dependency on plastics by eliminating your daily use of plastic bottles and replacing your warped plastic food containers. Borosilicate glass lasts far longer than plastics and can be reused every day for years on end. Best of all, a borosilicate thermos or water bottle can keep your beverages hot or cold far longer than a standard plastic bottle.
Consider switching from plastic to borosilicate glass and do your part to save the planet. It's stylish, durable, and cheaper in the long run than buying plastic bottle after plastic bottle.
Is Borosilicate Glass More Expensive than Normal Glass?
If we compare two glass baking dishes'one made from soda-lime glass and the other made from borosilicate glass'the borosilicate product will most likely be more expensive. This comes down to the manufacturing process needed to produce the material:
' Composite materials ' Boron trioxide is far less common than sodium and calcium. It makes up just 0.001% of the Earth's crust and is, therefore, more expensive to use than other elements.
' Energy consumption ' Borosilicate glass only melts at extremely high temperatures. It, therefore, requires a massive amount of energy to transform the composite materials into a sheet of malleable glass. More energy consumption drives up the cost of production.
' Higher quality ' After going through an intense production process, finalized borosilicate glass objects are considered high-quality glassware and therefore cost more than standard annealed glass.
As far as we are concerned, though, borosilicate kitchen and glassware are well worth the added price. Thanks to its higher durability and heat resistance, borosilicate glass containers will last far longer than traditional glass kitchenware, saving you the cost of replacing your broken or damaged objects in the future.

You've finally settled on a car you like, but the sales pitches don't stop there. Now the salesperson is using time-tested tactics to upsell you on important-sounding features like rustproofing, VIN etching and extended warranties. But is a new car protection package worth it?
Consider carefully before moving forward with these added features. They're often unnecessary or available elsewhere for cheaper. You will pay more interest if you roll the cost of these add-ons into your car loan. You can figure out how much you'd actually be paying with an auto loan calculator.
Dealer options are accessories and equipment that the dealer adds to the vehicle to increase the sales price of the vehicle. There are three types of options you may come across:
The vehicle's manufacturer approves options installed at the factory and port. They are typically included in the new vehicle's warranty. You'll find them listed on the official window sticker that's required for new cars. Moreover, the cost won't vary from dealer to dealer.
In contrast, dealer-installed options aren't approved by the manufacturer. So, they aren't included in the vehicle's warranty. They are not listed on the official window sticker, but they should be detailed on a second sticker on the car. Also, because the dealer installs them, prices vary by dealership.
In general, many dealer options are overpriced and used to increase profits on new vehicle sales.
If you are buying a new car, check the vehicle's stickers for add-ons. While you typically can't negotiate factory- and port-installed options, you may have some wiggle room with dealer-installed options.
Here are the six worst dealer options ' and the smartest alternatives to consider instead.
Dealer-applied undercoating can cost as much as $1,000 or as little as $550. It depends on the car, the type of treatment package ' basic or premium ' and whether it includes extra options like sound-deadening. It can be sold to new car buyers as a separate dealer option or be included in a pricey bundle called an 'environmental protection package.' These packages may include paint sealant and fabric protection.
'Cars leaving the factories today all have excellent rustproofing,' says Mike Quincy, automotive writer at the Consumer Reports Auto Test Center in Colchester, Connecticut. '[Dealers] have an incentive to do it because there's a fair amount of markup they can get on these services.'
Auto Car
Why you should skip it
All new cars already come with rustproofing, and some automakers will void the factory corrosion-perforation warranty if the car is undercoated by a third party.
Some dealers will provide fabric protection, which is designed to protect your seats from stains.
'A lot of dealers will also eagerly pitch you fabric protection, which is basically a spray that they will put on ' a spray that costs them almost nothing, but for which they might then charge you $100 or more,' Quincy says.

'If you really need additional fabric protection, all you have to do is buy a bottle of Scotchgard,' says John Nielsen, national director of auto repair and buying at AAA.
This dealer option is often promoted by showroom salespeople as a product that offers new cars a year-round no-wax shine that provides a long-lasting barrier against the environment. Protective paint sealant can cost the new car buyer well over $400. You might also see paint and fabric protection bundled together.

Most automotive paints today are durable finishes that benefit much more from regular washing and waxing, says Nielsen.
VIN etching is a procedure that allows you to make an adhesive plastic stencil containing your car's vehicle identification number, or VIN. You then place that stencil on a window and apply a special acid solution that chemically burns, or etches, the number onto the glass.
VIN etching can be a deterrent to thieves because it makes it nearly impossible for them to profit from selling windows and windshields and makes it more difficult to find a way to dispose of a car once it has been stolen. In fact, it's recommended by police and auto insurance agencies. Some insurers will even offer a discount on the comprehensive portion of your car insurance or waive your insurance deductibles if your car has the feature.
It's a straightforward process, but VIN etching as a dealer option can cost the car buyer from $200 to $300. If you do it yourself, you can shave off over $150.

Why you should skip it
If you'd like to do VIN etching, it's cheaper to use a do-it-yourself kit, which runs from $20 to $40 online.
As a dealer option, basic extended warranty policies can start at $1,000 and climb to several thousand dollars for luxury and high-performance cars.
Extended warranties offer bumper-to-bumper protection, covering everything on your car ranging from major system repairs, heating or air issues and engine problems. Extended warranties, on the other hand, do not cover components commonly replaced in routine maintenance.
Plan prices vary by mileage, the term of coverage and deductible level. Consider whether the extended warranty is worth it before buying.
New vehicles typically already come with manufacturer warranties. Even if you're buying used, you don't need to get the warranty on the day you buy the car. So, you can shop around if you really want one.

It's often better to use the money you would spend on an extended warranty for the recommended maintenance that your car requires.
No matter what your tires are filled with, nitrogen or oxygen, the four wheels pushing your vehicle along will inevitably deflate. Tires can lose air due to a hole in the tread, a poor seal or just general vehicle wear and tear. But many dealers will encourage buyers to add nitrogen to their tires, which can cost up to $400, claiming it will keep your tire pressure from fluctuating.
Unless you are a race car driver needing more consistent pressure from your tires, the additional cost is not worth it. Plus, the air they provide may have no more nitrogen than the air you're breathing. (In fact, a new FTC car dealer rule currently under review would ban dealers for charging extra in these cases.)
If you really want nitrogen, stopping by a local body shop will cost you $5 to $10 per tire.

It is best to save your money and keep an eye out for any tire damage that will likely occur with vehicle age.
The right options on a vehicle can enhance your driving experience and even boost the car's value when you are ready to sell it or trade it in. But you don't have to accept the dealer-installed options you don't want.
If you find that a new vehicle has some dealer-added options, you can ask the dealer to remove them and adjust the vehicle's sales price accordingly. In some cases, it may not be possible ' for example, if rustproofing or paint protection has already been applied, it may not be removable.
Try to negotiate the price of the vehicle like you normally would if the dealer can't or won't get rid of an option. Again, there's no guarantee that this will work, but even showing a little initiative in negotiation can change the course of the conversation.
For example, consider calling another dealer in the area to get an idea of what it might charge for certain options or even see how much it would cost if you did it yourself. This can give you a good reference point in your negotiations for the best out-the-door price.
If a dealer doesn't budge, you can pay for the car as-is or walk away.
Dealer-installed options aren't always worth it. Checking what you're being charged for is important. While dealers aren't always willing to remove options they have installed or negotiate on the price, know that these options aren't standard. You don't have to accept them.
As with every other aspect of the car-buying process, shop around and compare prices and options from multiple dealers in your area. Ensure you get the best deal available.
