If you are shopping for some dedicated blender containers, you may compare glass blender jars vs plastic blender jars. The best blenders, after all, often integrate with one or the other. Keep reading to learn the differences and use case scenarios between the two.


  • Glass blender jars feature a more refined look than plastic blender jars, and this vintage appeal tends to last longer.
  • Glass jars are heavier and less durable than plastic jars, as they are prone to breaking.
  • Plastic jars can develop scratches over time, which can make the cleaning process more difficult, and can develop food odors.

Differences Between Glass and Plastic Blender Jars

The main difference is the materials used during construction, as one is made from glass and the other is made from plastic. This difference in materials causes each type to be more useful in different scenarios, though these differences are not as stark as when comparing food processors vs blenders.

Here are more ways in which glass and plastic blender jars differ and some ways in which they are similar.

Insider Tip

Make sure your blender jar is dishwasher safe before attempting to clean it in your kitchen’s dishwasher.

Weight and Durability

Glass jars are much heavier and break easier than plastic jars. If you suffer from arthritis or a related ailment, handling a plastic blender jar would be the easier choice. Plastic jars are also more durable. Plastic jars are nearly impossible to break, though they can become scratched with repeated use. Glass jars, on the other hand, can break from one accidental fall from the kitchen counter.


Most plastic blender jars are dishwasher-safe, and only some glass jars can be washed in the dishwasher. Though it must be noted, if a plastic jar becomes scratched along the interior, it will become more difficult to clean, as the grooves will trap food particles and the like. You should make note of how the rubber gasket goes on the blender before you completely dismantle the jar to make sure it doesn’t leak once you put everything back together. Also, some plastics can develop a smell over time, whereas a glass jar will almost never develop a smell with repeated use.

Glass jars tend to provide a more refined aesthetic, making it the preferred choice if your blender sits on the countertop when not in use. Additionally, glass jars will retain their looks over time, whereas plastic jars get scratches and can become dull in color.

Blending Efficiency

The materials used in the blender jars make little to no difference when it comes to blending performance and overall efficiency. This is due to the fact that blending power is derived from the blender’s motor and not the jar or container. Though the type of jar has no bearing on the motor’s power or blending process, considering a grain mill vs a blender does, as a grain mill tends to be less powerful than a blender. Also, you should remember that if your blades are dull, your results won’t be pleasant, no matter the material of the jar. If your blades are dulling, you should learn how to sharpen blender blades to make sure your blender stays performing optimally.

What are the key features to consider when buying a blender with a glass jar?

You should always look for a high-end blender with a good motor at the onset of shopping. Powerful blenders are great no matter which type of blender jar is used.

When do you need blenders with a glass jar?

As with any kitchen appliance, it depends on personal preference. Glass jars will not develop scratches during use, so it’s a good idea to use them while blending ice and other potentially damaging ingredients. A stainless steel pitcher or stainless steel jars may be even better in this regard.

What is the best blender jar material?

This depends on personal preference and what you are using the blender for. Blenders with glass jars have their place, as do commercial blenders with stainless steel pitches and those with plastic jars.
