Last Updated on March 23, 2024 by Lori Walker

When it comes to selecting durable and dependable glass cookware, brands like Pyrex and Anchor Hocking are frequently the preferred options.

These two have long been the biggest names in the bakeware market, but how do their glass products compare?

As a passionate cook, I had the pleasure of using both brands and experiencing their remarkable qualities.

In this detailed comparison review of Pyrex vs Anchor Hocking, we’ll tackle several crucial factors to help you decide which brand is the more reliable choice.

Battle of the Brands: Anchor Hocking or Pyrex?

Anchor Hocking Glass Containers

Pyrex and Anchor Hocking are popular glass kitchenware staples made from durable materials to withstand high heat.

Anchor Hocking bakeware was first established in 1905, while Pyrex was founded in 1915. Both formerly used borosilicate glass but presently use soda-lime glass to withstand being dropped.

Pyrex offers a variety of products, such as tempered food storage containers and food keepers. However, Anchor Hocking offers a broader selection of products.

Aside from what Pyrex has to offer, Anchor products like bottles, cake stands, platters, cups, and pantry organizers are widely available in the market.

Also, based on my experience, Pyrex glassware is more expensive than Anchor Hocking glassware. But how does All-Clad Differ from Cuisinart?

Main Differences 

History & Location

Pyrex brand was created in 1915 by a team of researchers as they launched their first line of bakeware, which includes loaf pans and pie plates [1].

Anchor Hocking brand was formerly known as Hocking Glass Company, and it was a product called Anchor Cap and Closure Corporation in 1937.

German Scientist Otto Schott made borosilicate glass in 1908 [2]. Pyrex started as Corning Glass Works, and the company invented “Nonex,” made of borosilicate glass in 1908.

It was only in 1913 when Bessie Littleton, wife of one of the Corning scientists, Jesse Littleton, requested her husband to bring home a Nonex glass for her to try out since her glass bakeware cracked while in the heating oven.

As a result, this led the company to venture into the cookware industry. In 1915, they became known as the Pyrex brand when they launched their first line of Pyrex glassware.

On the other hand, Anchor Hocking was established in Lancaster, Ohio [3], under the name Hocking Glass Company in 1905.

In 1937, the company merged with the Anchor Cap and Closure Corporation. The merged entity became known as Anchor Hocking Glass.

Assortment 

Pyrex may have the best-selling items, but Anchor Hocking has a broader selection of products.

Pyrex offers various cooking, baking, storage, and serving products, including baking dishes, cake pans, pie plates, cold packs, loaf pans, mixing bowls, measuring cups, food storage containers, and more.

In comparison, Anchor Hocking offers a wider variety of products than Pyrex. In addition, it also manufactures pantry organizers, water bottles, cups, food-grade glasses, measuring cups, platters, and cake stands.

Borosilicate Glass vs Soda Lime Glass 

Historically, both Pyrex and Anchor Hocking used borosilicate glass in the production of their glass containers and other products.

It is a material that can resist thermal shock or extreme temperature changes; the brands want kitchenware that does not break easily when accidentally dropped.

As of today, both brands use soda lime glass [4], which is far inferior to borosilicate and is more prone to shattering when exposed to sudden or extreme temperature changes.

However, it is still durable and suitable for everyday use compared to plastic containers that leach chemicals.

Storage Set

I noticed that Pyrex offers more variety of storage sets than Anchor Hocking. However, Based on my experience, Pyrex is a bit pricier than Anchor Hocking.

Both storage sets come in different sizes and shapes, and their glassware is made with tempered glass, which makes them freezer, dishwasher, and oven-safe.

However, we must note that Pyrex containers are only recommended in the oven preheated up to 350 degrees F while Anchor Hocking containers can reach up to 425 degrees F.

In addition, if you are concerned with the capacity of container sets, Pyrex offers more selection.

Both bakewares include measure cups that are microwave-safe too.

Lids

Since I got storage containers from the two brands, I compared their plastic lids. The plastic lids of both brands are BPA-free and airtight.

I observed that some of the plastic lids from Pyrex containers could fit into Anchor Hocking glassware. However, I recommend buying replacement lids for the bowls to ensure they are airtight.

Also, Anchor Hocking cups are heavier, which may affect the usability but not to some extent.
