Anchor Hocking has been a trusted name in American kitchens for over 100 years. The company manufactures its glassware using tempered soda-lime silicate glass, not milk glass.

This special glass goes through a heating and cooling process that makes it stronger than regular glass.

Key facts about Anchor Hocking glass:

• Made from tempered soda-lime glass
• Designed to handle temperature changes better than regular glass
• Manufactured to meet strict safety standards
• Non-reactive material that won’t affect food flavors.

WHICH ANCHOR HOCKING PRODUCTS ARE OVEN SAFE?

Not all Anchor Hocking glassware can go in the oven. Here’s what you can and cannot use:

Safe for Oven Use:

• Baking dishes and casserole dishes
• Measuring cups (glass versions)
• Mixing bowls
• Food storage containers (oven-safe models)
• Batter bowls

NOT Safe for Oven Use:

• Wine glasses
• Drinking glasses

Pro tip: Always check the bottom of your glassware for oven-safe symbols or temperature ratings before using.

MAXIMUM SAFE TEMPERATURE FOR ANCHOR HOCKING GLASSWARE

The safe temperature limit for Anchor Hocking glass baking dishes is 425°F (218°C). Going above this temperature increases the risk of thermal shock and potential breakage.

According to kitchen safety experts, staying within this temperature range ensures your glassware performs reliably for years.

Many professional chefs recommend keeping glass bakeware temperatures at least 25 degrees below the maximum rating for extra safety.

HOW TO USE ANCHOR HOCKING GLASSWARE SAFELY IN THE OVEN

Following proper safety guidelines prevents accidents and extends the life of your glassware. Here are the essential do’s and don’ts:

Do These Things:

1. Preheat gradually – Place glass dishes in a cold oven and let them heat up together
2. Use oven mitts – Glass gets very hot and stays hot longer than metal
3. Place on dry towels – Put hot dishes on dry kitchen towels, not cold countertops
4. Allow cooling time – Let dishes cool to room temperature before washing

Never Do These Things:

1. Don’t use damaged glassware – Chips, cracks, or scratches weaken the glass structure
2. Don’t exceed 425°F – Higher temperatures can cause thermal shock
3. Don’t add cold liquids to hot dishes – This creates dangerous temperature shock
4. Don’t place on stovetop burners – Direct heat can shatter the glass
5. Don’t move from freezer to hot oven – Allow dishes to reach room temperature first.

CAN ANCHOR HOCKING GLASS GO FROM FREEZER TO OVEN?

This is one of the most common questions people always ask. The answer requires careful handling.

Yes, but with important steps:

1. Remove the dish from the freezer
2. Let it sit at room temperature for 15-30 minutes
3. Place in a cold oven
4. Then turn on the oven to your desired temperature

Why this matters: Extreme temperature changes cause thermal shock. Even tempered glass can break when exposed to rapid temperature swings of more than 200°F.

Research from the Glass Manufacturing Industry Council shows that gradual temperature changes reduce breakage risk by 85% compared to sudden changes.

MICROWAVE SAFETY WITH ANCHOR HOCKING GLASSWARE

Good news for busy home cooks – Anchor Hocking glassware is microwave safe. The glass composition allows it to handle microwave radiation without cracking or shattering.

Microwave best practices:

• Let food rest before removing

• Use medium power for reheating

• Avoid metal trim or decorations

• Use microwave-safe lids or covers.

UNDERSTANDING GLASS BREAKAGE: WHY DO GLASS DISHES “EXPLODE”?

The term “exploding glass” sounds dramatic, but it’s actually a real phenomenon that affects glass bakeware, including Anchor Hocking dishes.

Understanding why this happens can help you prevent it in your kitchen.

What Actually Happens When Glass “Explodes”

When people describe glass dishes as “exploding,” they’re referring to a sudden, dramatic breakage that creates a loud popping sound and scatters glass pieces.

When glass goes rapidly from something cold to hot (like a freezer to an oven) or vice versa, it can experience “thermal shock.”

Different sections of a piece of bakeware can expand or contract differently and cause it to lose its structure, resulting in a shattering effect.

The science behind the “explosion”:

• Thermal shock is when an object abruptly goes through a drastic temperature change, causing it to fracture as it expands or contracts
• Tempered glass breaks into small, cube-shaped pieces (safer than large shards)
• The breaking process releases stored energy, creating the distinctive “pop” sound
• This safety design protects you from dangerou,s sharp edges

Statistical Reality of Glass Breakage Incidents

The numbers tell an important story about glass bakeware safety. The U.S. Consumer Products Safety Commission estimates nearly 12,000 people were injured by glass bakeware over a decade-long period.

That figure includes injuries from dropping glass and breaking it – but also from bakeware that shattered on its own.

In addition, a U.S. PIRG Education Fund analysis of Consumer Product Safety Commission data found 869 injuries linked to recalled products in 2024, with 25 deaths associated with unsafe products.

Why Anchor Hocking Dishes Break: The Main Culprits

Based on manufacturer guidelines and safety research, here are the primary reasons Anchor Hocking baking dishes fail:

Temperature-Related Failures:

1. Exceeding safe temperature limits – Cooking at a higher temperature than 425°F
2. Rapid temperature changes – Moving from freezer to hot oven without gradual warming
3. Placing hot dishes on cold surfaces – Creates immediate thermal shock

Physical Damage:

1. Using compromised glassware – Using chipped, cracked, or noticeably scratched bakeware products
2. Impact damage – Hard hits or impacts that occur during usage, washing, or storing

Improper Use:

Contact with hot surfaces – Placing bakeware on a recently used or still warm stovetop burner.

Wrong heating methods – Use on a stovetop, broiler, or toaster oven.

THE GLASS TYPE FACTOR

Understanding glass composition helps explain breakage patterns.

Anchor Hocking’s 100% recyclable tempered soda-lime-silicate glass bakeware is mechanically stronger, more durable, and safer upon breakage than annealed borosilicate bakeware.

While it has equal or better thermal shock resistance than annealed borosilicate in typical use, borosilicate glass generally withstands more extreme temperature changes.

Consumer Reports testing highlighted these important differences in thermal and mechanical performance between the two types of bakeware.

Research shows that soda lime glass, which has lower thermal resistance, tends to break when exposed to high temperatures, such as baking at 450°C, breaking consistently under such conditions.

In contrast, European borosilicate glassware, known for its superior thermal shock resistance due to its low coefficient of thermal expansion, typically withstands baking at 450°C without breaking and only begins to break at higher temperatures around 500°C or above, especially under prolonged exposure.

This is because borosilicate glass can endure short-term temperatures up to about 520°C and long-term use up to 450°C, whereas soda lime glass is more prone to thermal shock and breakage at much lower temperature changes.

Prevention Is Key: How to Avoid Glass Breakage

The good news is that glass breakage is largely preventable with proper handling:

Temperature Management:

• Never exceed 425°F with Anchor Hocking dishes
• Allow gradual temperature changes (15-30 minutes between temperature zones)
• Avoid placing hot dishes directly on cold countertops

Inspection and Care:

• Check dishes for chips, cracks, or scratches before each use
• Replace damaged pieces immediately
• Handle carefully during washing and storage

Proper Usage:

• Use only in conventional ovens and microwaves
• Avoid broilers, stovetops, and toaster ovens
• Place hot dishes on dry towels or heat-resistant mats

Industry Response and Safety Improvements

Manufacturers like Anchor Hocking have responded to safety concerns by:

• Providing clearer usage guidelines
• Improving tempering processes
• Offering better consumer education about thermal shock
• Maintaining strict quality control standards

Another potential failure mode of glass bakeware is a thermal shock, which results from a significant and sudden temperature change, according to Anchor Hocking’s own safety information.

The Bottom Line on Glass Safety

While the phrase “exploding glass” sounds alarming, the reality is that proper use dramatically reduces risk. Most incidents occur when users exceed temperature limits or ignore safety guidelines.

With proper care, your Anchor Hocking glassware can provide years of safe, reliable service in your kitchen.
