JSG Oceana Borosilicate Glass Bakeware Review


JSG Oceana Glass Bakeware


Having the right borosilicate glass bakeware to make pies and casseroles for dinners or holidays, can be difference between creating meals that are delicious and beautiful to look at, or less-than-appealing fare.

I was recently contacted by the folks at JSG Oceana Borosilicate Glass Company, a subsidiary of Jeanette Specialty Glass.  They asked me to review their Borosilicate glass bakeware set, which consists of a 9.5 Inch Pie Dish, a large 3 Quart Casserole Dish and a 9 Inch x 13 Inch Baking Dish.

I will admit, while I am very familiar with glass bakeware, like Pyrex and Anchor Hocking, I had never heard of JSG Oceana borosilicate glass bakeware until they contacted me.  It may be due to this line of  Borosilicate glass bakeware is only available online or through the JSG Oceana website.


Note: I was not compensated for this product review, and the views and opinions are my own.

I am sure you will be as impressed as I was by JSG glass bakeware made with sturday borosilicate glass.  The quality construction, sturdiness and large size of this professional quality glass baking set made it stand out.

You can take pride in knowing you are getting American quality and craftsmanship in every piece of JSG Oceana glass bakeware.



Hard Roc Borosilicate Glass Bakeware


Most glass bakeware is made from soda lime glass, which is relatively inexpensive, chemically stable, and reasonably hard.  Unfortunately, it’s not shatter-proof.  You need to take care not to drop it.  Cheap glass bakeware can explode when under extreme oven temperature.

JSG Oceana Glass Bakeware is made from Hard Roc Borosilicate glass,which is a hard heat resistant, scratch resistant and shatter-proof manufactured glass made with silica and boron trioxide, that was originally developed in Germany in the late 19th century, and produces a tough industrial-grade glass.

I’m sure you’re concern like most home chefs, is will it withstand the high heat of my oven and will it resist breaking if I accidentally drop it, like regular glass?

The answer is yes!  Another advantage of Borosilicate glass bake compared to other types of glass bakeware is that it is scratch resistant, and it’s non-porous surface doesn’t stain and won’t absorb smells from the food.

Since food doesn’t stick to it, cleaning off baked on food remnants is relatively easy.

How Does  JSG Oceana Borosilicate glass bakeware compare to Pyrex?


Pyrex was originally made from Borosilicate glass.  It was the go-to glass bakeware for home cooks and professional chefs for many years.

The company was sold to Corelle Brands.  They changed their formula from borosilicate glass to soda lime glass to make the cookware lighter and cheaper.  As you can expect, complaints began to roll in.   Pyrex glass bakeware would sometimes crack due to heat, or break if dropped and even explode in the oven.

JSG Oceana has continued the tradition of excellence started by Jeanette Glass Company nearly a century ago, and still uses the superior Borosilicate glass, which is a stronger material to soda lime glass.

Borosilicate Glass is Much More Resistant to Thermal Shock

Borosilicate glass has a very low CTE (Coefficient of Thermal Expansion) whereas soda lime glass has a very high CTE.



Is it a bit more expensive, but as the expression goes, “you get what you pay for.”

When I opened the box, I immediately noticed the sturdy and heavier construction and thicker glass as compared to our Pyrex glassware, and those from other glass bakeware manufacturers that use soda lime glass.  You will immediately notice and feel the difference!

Every JSG Borosilicate glass bakeware includes a label that shows the features and how the dish can be used.

Deep Casserole Dish


The JSG Oceana Borosilicate Glass Casserole Dish is extra deep to maximize your ability to make a small or large casserole.

The thick Borosilicate  glass will ensure the dish can withstand years of use without the worry of it breaking or cracking.

I tried making my favorite broccoli casserole in the deep casserole to test this glass bakeware out.  It definitely performed well.

The dish used a full head of broccoli and 2 large packages of mushrooms.  You can see there is plenty of room in this large baking dish.

The dish baked at 400 degrees F for 40 minutes.  While the hot dish required an oven mitt to handle it, the glass bakeware worked perfectly.

How did the Baking Dish Perform?

I used the JSG Borosilicate glass baking dish to make chicken.  Overall it performed well.  The wide handles work well to grab the dish when putting it into or taking it out of the oven.

The thick wall construction of the Borosilicate glass baking dish gives you confidence that it won’t crack or break due to the heat and pressure of the oven at high temperatures over 400 degrees F.

It cleaned easily with warm soapy water and a sponge.

The only drawback I found was the 9″x13″ baking dish could be a bit tight to cook a large cut up chicken, roast, lasagna or other dish.

The Oceana glass baking dish should also come in a 10″x14″ size.
