Simax vs Pyrex

While Simax and Pyrex are well-known brand names that produce a range of glassware products, including bakeware, cookware, and laboratory glassware, they have few differences.

Find below the distinctions between Simax and Pyrex glassware brands:

Simax glass is manufactured in the Czech Republic, while Pyrex glass is produced by various manufacturers worldwide, including the United States, Europe, and Asia.

This can sometimes lead to differences in quality control standards and manufacturing techniques.

Simax glass product lines are made ONLY with Borosilicate glass but Pyrex is either made up of Borosilicate glass or soda lime tempered glass.

The Simax Borosilicate glass is more durable and has greater thermal shock than Pyrex soda lime glass.

Some users report that Simax glassware tends to be thicker and more durable than certain Pyrex products. However, this can vary depending on the specific items being compared.

In terms of pricing, Simax and Pyrex products can differ based on factors such as brand reputation, manufacturing costs, and distribution channels.

In some cases, one brand may be more affordable than the other for comparable items.

Simax and Pyrex may offer different design aesthetics and styles in their glassware collections. This can include variations in shapes, sizes, and decorative features.


There is nothing compared to cooking with transparent and healthy cookware made of glass and not just any type of inferior glass but versatile and durable Borosilicate glass.

You don’t have to break the bank to cook meals that are fresh, healthy, and delicious because, with the Simax Glass cookware, you are double sure that harmful toxins won’t leach into your food.

Perfect for simmering and can serve as a saucepan, this healthy glass cookware is suitable for both electric stovetops and gas stovetops.

One beautiful quality about this Simax glass cookware is that the handles stay cool to the touch while you cook but the pot is hot.

As highlighted above, the Simax glass cookware is proudly made in the Czech Republic and the Borosilicate glass cookware is heat and cold-proof (up to 572° F and down to -40° F), so you do not need to worry about it cracking or exploding.

Finally, they are safe for microwave use, dishwasher and will make a beautiful gift for newlyweds or for preparing all your Christmas and Thanksgiving dishes.


Determining which brand is “better” between Simax and Pyrex is dependent on individual preferences, specific product lines, your budget, and intended use.

While both brands are reputable and known for producing high-quality glassware using Borosilicate glass or soda lime material, your decision will be influenced by this.

For example, if you plan to purchase glass cookware for direct flame like your electric or glass stovetop, then you should go for Simax Borosilicate cookware or the old Pyrex Borosilicate glass product line.

But if you need a glass bakeware that requires less temperature and less thermal shock then soda lime Pyrex glassware will suffice.

Finally, use Borosilicate glass for high temperatures, and chemically corrosive environments and stay with soda lime glass where rapid temperature changes aren’t required.

Again, it’s ultimately a matter of personal preference, so we recommend considering factors such as pricing, design, availability, and any specific features that are important to you when making your decision between Simax and Pyrex glassware brands.


To determine between Corningware and Pyrex, which is better, let’s first see the major differences between Corningware and Pyrex:

Corningware is majorly made with Pyroceram or ceramic material which is somewhat commonly called glass ceramic while Pyrex is either made with soda lime tempered glass or Borosilicate glass material.

Corningware is proudly made in the USA while Pyrex is made in the USA and Europe.

CorningWare is often more versatile for oven-to-table use due to its ceramic-like appearance and design than Pyrex.

Pyrex, on the other hand, is commonly used for a wider range of purposes, including baking, cooking, food storage, and even laboratory applications but Corningware isn’t used for laboratory applications.

Pyrex offers a wider variety of shapes, sizes, and designs compared to CorningWare, which may provide more options for different cooking and serving needs.

While both can withstand high temperatures, CorningWare may have a slight edge in thermal shock resistance due to its glass-ceramic composition.

Pyrex is more fragile than Corningware because of its glass makeup and requires extra caution and care.

Overall, while they share a few similarities, the choice of which is better between CorningWare and Pyrex may depend on personal preferences, specific cooking needs, and budget.


Stoneware and Pyrex are both types of oven-safe cookware, but they have some differences:

Stoneware is made from clay fired at a high temperature, resulting in a durable, non-porous material that retains heat well and is great for baking dishes like casseroles and bread.

It’s also known for its rustic appearance and ability to develop a seasoned patina over time.

Pyrex, on the other hand, is made from either Borosilicate glass or tempered glass, which is resistant to thermal shock and can withstand high oven temperatures.

It’s commonly used for baking and cooking, as well as for storing food in the refrigerator or freezer. Pyrex dishes are transparent, making them convenient for monitoring food while it cooks.

Stoneware tends to be more versatile in terms of what you can do with it. You can use it in the oven, microwave, dishwasher, and even on the stovetop depending on the specific piece.

It’s also known for its ability to evenly distribute heat, making it great for cooking, baking, and roasting.

Pyrex, being made of glass, is also versatile but has some limitations. While it’s safe for the oven, microwave, dishwasher, and freezer, it’s not every Pyrex product line that is suitable for use on the stovetop.

Stoneware casserole baking or roasting dish can confidently go from freezer to oven (without preheating) and can handle over 500 degrees F more than Pyrex glassware.

Finally, Pyrex is known for its non-reactive properties, meaning it won’t absorb odors or flavors from food and is safe for acidic ingredients but some stoneware baking dish might absorb the odor or flavor of your food.


Yes, the Simax glassware brand is of good quality because they are made of Borosilicate material which is highly durable, resistant to thermal shock, transparent, and non-reactive, meaning it won’t impart any unwanted flavors or chemicals to whatever it comes into contact with, making it ideal for food, kitchenware and laboratory applications.


While Pyrex glass is durable and versatile for various home and laboratory uses, there are still at risk for breakage.

Below are actions that might lead to Pyrex breaking:

When we ignore to read the care and instructions of the manufacturer and presume we know, we may mishandle our Pyrex glass, resulting in shattering.

Avoid sudden extreme temperature changes especially from the freezer to the hot oven or the sink, this action causes Pyrex to shatter, to prevent this, place your Pyrex on a surface that can absorb the temperature like a towel, cutting board, or cooling rack.

Adding hot Liquid to hot Pyrex soda lime glassware might cause it to break, it is advisable to allow it to cool down before adding water.

Placing hot Pyrex glassware on a cold or wet surface might cause it to break especially soda lime Pyrex glass.

Rushing to place Pyrex soda lime glass or even Pyrex Borosilicate glass into the refrigerator or freezer without allowing it to cool for a while might lead to breakage.

Using soda lime Pyrex glass under the broiler, toaster or stovetop will certainly lead to breakage as it is not designed for such heat.

Heating empty or microwaving empty Pyrex glassware will lead to its breakage.

Using damaged Pyrex with chips, cracks will cause it to explode, kindly throw out such Pyrex glassware that is damaged to avoid injury.

Finally, always Preheat the oven first before placing your Pyrex glassware with food in the Oven.


Pyrex glass has various advantages that undoubtedly outweigh its downsides; yet, the following are some disadvantages of Pyrex glass:

Pyrex glass is durable and heat-resistant more than regular glass, but it can still break if subjected to sudden temperature changes, such as going from hot to cold or vice versa, which could be considered a disadvantage.

Pyrex glassware tends to be more expensive than other types of glassware due to its durability and heat resistance.

Pyrex glassware is often heavier than alternatives, which can make it less convenient for certain applications, such as transporting or handling.

It is not all Pyrex glassware that is suitable for direct flame because it will shatter due to the intense heat.
