Borosilicate Glass vs Plastic Blenders - Which is Better?

If you’re on the lookout for a good blender, chances are that you’ve wondered about the difference between glass blenders and plastic blenders. One thing's for certain - when it comes to food preparation, many experts agree that glass is better than plastic for many reasons.

What is Borosilicate Glass?

Not all glass is created equal. Borosilicate glass is a special type of glass that is made of safe and environmentally-friendly silica and boron trioxide as its main components. It is known for its extreme temperature resistance and for being more resistant to thermal shock than common glass, meaning it will not crack under extreme or sudden temperature changes.

Its excellent durability makes it the glass of choice for high-end restaurants, wineries, and high quality cookware and bakeware.

What is BPA-Free Plastic? Is it safe?

We are all familiar with plastic being used in many common household items, due to its advantages of being inexpensive, light and durable. The cheapest blenders tend to be made of plastic due to its low cost to manufacture. However, this comes at the cost of health. These days, many companies like to slap on a BPA-free label to their product and claim it ‘safe’. However, scientists warn that this may not be the case, as research shows that BPA-free plastic is linked to genetic diseases.

Although plastic is still widely used today, you can take steps to reduce your risk of exposure such as switching to a borosilicate glass blender like the Aura Blender.

Factors to Consider when Choosing a Borosilicate Glass Blender vs Plastic Blender - A Detailed Comparison

1. Appearance

If you value appearance and clarity through the jar, then a high-end borosilicate glass blender is a better choice than a plastic blender. Glass looks and feels more expensive than plastic because it is! It is also more scratch-resistant, doesn’t discolour over time and is overall more durable in the long run, so your blender looks as good as new for a longer time.

A plastic blender can become scratched and less clear over time. In comparison, a borosilicate glass blender such as the Aura Blender has an aesthetic quality to it and will retain its beautiful and refined look for a long time.

❌ Prone to Scratches

✔️ Does Not Stain or Discolour

❌ Discolours Over Time

✔️ Does Not Retain Odour

2. Heat Resistance

One of the most famous facts about borosilicate glass, and a big reason why many companies use it for top-of-line cookware and bakeware, is its ability to withstand hot and cold temperatures easily and safely. A borosilicate glass blender such as the Aura Blender will not crack under extreme or sudden temperature changes. For you, this means that you can pour hot tea or coffee without worrying about cracking the glass.

On the other hand, a plastic blender should never be exposed to heat as this breaks down the plastic, allowing BPA and other harmful chemicals to leach into foods.

✔️ Warm & Cold Blends

❌ Cold Blends Only

✔️ Extreme High & Low Temperature Resistance

❌ Dangerous if Exposed to Heat


3. Food Safety & Health

A glass borosilicate blender is a step towards good health, as experts warn of the dangers of plastic, even BPA-free ones. The chemicals in a plastic blender can leach out of the plastic and into the food and beverages you make and drink. Some of these chemicals are linked to genetic disorders and reduced fertility. Furthermore, leaching occurs faster and more greatly when the plastic is exposed to heat.

The ‘BPA-free’ labels on plastic blenders are meant to reassure users that it is safe to drink out of, but growing research shows that it may not be as safe as companies would like you to think, as published by the National Geographic, The Guardian, and Harvard.
