Bakeware Facts


The best bakeware is safe. For decades Anchor Hocking has made glass products with no recalls and an excellent safety record. That doesn’t happen by accident. We design and manufacture our bakeware with safety in mind, and we always advocate that all customers follow recommended safety precautions.

SAFETY WARNING: Always check the bottom of glassware to ensure it is microwave and oven safe,  and always use dry oven mitts or potholders when removing glass from the oven or microwave.


Glass is 100% recyclable and Anchor Hocking has always take great efforts to maximize the environmental benefits of its products.

Which Anchor Hocking Products are considered bakeware?


Anchor Hocking bakeware is safe. We are proud that our products have been a safe and reliable part of American kitchens for generations. Anchor Hocking has never had any of its products recalled by the Consumer Product Safety Commission (CPSC). Specifically, Anchor Hocking’s tempered soda-lime-silicate glass bakeware has been in the marketplace for over 40 years with an excellent safety and customer satisfaction record.

Moreover, even with the obvious and known limitation that glass can break, the number of injuries associated with the use of glass bakeware is remarkably small. The National Electronic Injury Surveillance Survey (NEISS), which is used by product safety experts to assess the risk of consumer products, shows that there are minimal claims of injuries resulting from glass bakeware unexpectedly breaking or shattering. Without doubt, Anchor Hocking’s glass bakeware is an extraordinarily safe product when used in accordance with safety and usage instructions.


Anchor Hocking manufactures in full compliance with the applicable industry standard set forth in Chapter 24 of The Cookware & Bakeware Alliance Engineering Standards for Cookware and Bakeware.


Today, all U.S. manufactured glass bakeware, regardless of manufacturer, is made from tempered soda-lime-silicate glass. Tempered or heat-strengthened bakeware is designed to strengthen the glass to be more durable and stronger than other glass products. A similar, although not identical tempering process is used for other glass products where safety is also important, such as automobile windows, sliding glass doors, and shower doors.

The tempering process is essential in making Anchor Hocking glass as strong and safe as possible. As a result of this tempering process, when Anchor Hocking tempered glass breaks, similar to other tempered safety glass products, it breaks into a number of pieces, most relatively small (some may be larger). Unlike non-tempered glass products, these pieces generally lack sharp edges when it does break, resulting in a lower likelihood of severe cuts from the broken glass. the best bakeware failure releases a level of energy that causes a loud sound that consumers have described as a “bang” or “explosion” resulting in the smaller shards being released outward. This method of failure is by design and is in fact a safety feature rather than evidence of a defect.

Damage to the glass can occur from improperly scouring with abrasives, use of sharp utensils, impact with other hard objects, and severe temperature changes. Mechanical breakage caused by an impact is the most frequent cause of failure. Accordingly, the soda-lime-silicate glass is stronger than other glass against impacts such as being hit against something or being dropped. Likewise, having the best bakeware break in a safer manner by breaking into pieces generally lacking sharp edges and shards is a priority. Finally, Anchor Hocking’s bakeware is as strong as other types of glass bakeware against stresses such as temperature changes. Tempering or heat-strengthening soda-lime-silicate glass achieves all these goals better than other glass processes.


Another potential failure mode of glass bakeware is a thermal shock which results from a significant and sudden temperature change. Consistent scientific testing for decades has established that tempered soda-lime-silicate bakeware is at least equal to or better than annealed borosilicate products in thermal shock resistance. In fact, when the decision was made to change from borosilicate to tempered soda-lime-silicate over 40 years ago, Anchor Hocking’s testing demonstrated a 40% improvement in thermal shock resistance for its tempered soda-lime-silicate glass.

What would cause Anchor Hocking’s bakeware to break?

Glass bakeware is not without limitations. While it is a healthier alternative to metal bakeware because no hazardous materials leach into your food and cooks often prefer it because it helps retain moisture and bakes more evenly; like all glass, it can break. Anchor Hocking bakeware is safe when its care and use instructions are followed. Regardless of the safety measures taken by Anchor Hocking to strengthen and ensure the quality of its products, misuse can lead to the failure of the bakeware.

It has been Anchor Hocking’s experience that the vast majority of failures are due to mishandling or improper care of the product, even with the best bakeware. It is important to note that the misuse often happens over time and the actual failure may occur at a later date. A few examples (but not an exhaustive list) of this type of mishandling are:

  • Scouring or improperly cleaning the bakeware.
  • Causing severe thermal shock by adding liquid to a hot dish, placing a hot dish into the dishwater, or placing a hot dish directly on a countertop rather than using pot holders, a pad, or a trivet.
  • Using chipped, cracked, or noticeably scratched bakeware products.
  • Hard hits or impacts that occur during usage, washing, or storing.
  • Cooking at a higher temperature than 425°F.
  • Use on a stovetop, broiler, or toaster oven.
  • Placing bakeware on a recently used or still warm stovetop burner.

Properly caring for and using your favorite bakeware is a critical step in maintaining its integrity and safety. Anchor Hocking’s bakeware must be properly cared for and used according to instructions for it to perform as expected.
