Is Corning Ware Microwave Safe?

Imagine pulling your grandma’s vintage Corning Ware out of the cupboard, ready to reheat that delicious lasagna you made last night.

But wait—can you safely pop this classic into your microwave, or will you risk a kitchen catastrophe? Fear not! We’re diving deep into the world of Corning Ware. Let’s explore the safety, versatility, and quirks of this beloved cookware.

Is Corning Ware Microwave Safe?

Yes, most Corning Ware is microwave safe, thanks to its Pyroceram material which resists thermal shock. However, there’s an exception – the Centura line, which is identifiable by its sculptured rim and plain edge without printed patterns, should not be used in the microwave.

Always check your piece for any metal parts or special finishes before heating, as these could cause issues. For all other Corning Ware products, you can safely use them to reheat or cook in the microwave, making them a versatile choice for kitchen tasks.

What is a Corning Ware

Corning Ware, a name synonymous with kitchen durability, has been a staple in American homes for over half a century. Crafted from Pyroceram, a unique glass-ceramic material, Corning Ware is renowned for its exceptional resistance to thermal shock.

This means you can take it directly from the freezer to the oven or stovetop without fear of cracking or breaking, highlighting its unparalleled durability.

Its non-porous surface ensures that your dishes won’t carry over flavors, odors, or stains, making it a go-to for everything from everyday cooking to special occasion meals.

When it comes to microwave safety, the vast majority of Corning Ware pieces are designed to be microwave safe. This includes their popular stoneware bakeware sets, which are also safe for the oven, refrigerator, freezer, and dishwasher, showcasing its versatility.

Why does Centura corning ware not microwave safe

The Centura line is identifiable by its sculptured rim, plain edge, and lack of printed patterns, should not be microwaved. This is because Centura was designed before the widespread use of microwaves, focusing instead on oven-to-table elegance.

If you come across a piece of Corning Ware without any decorative or stamped patterns, it’s wise to check if it’s Centura before heating. Remember, when in doubt, do not use it in the microwave to avoid any risk.

Safe Microwave Practices with Corning Ware

When using Corning Ware in the microwave, there are key practices to follow:

1. Avoid Metal

Ensure your Corning Ware piece has no metallic parts or finishes. Metal can spark and damage your microwave. Always inspect for metal before heating.

2. Temperature Management

Despite its thermal shock resistance, avoid extreme, sudden temperature changes. For instance, do not go from the freezer directly to the microwave. Let the dish sit for a bit if it’s coming from a cold environment to prevent potential cracking.

3. Lid Safety

Most glass or plastic lids accompanying Corning Ware products are microwave safe, but check for any metal components or special instructions.

4. Correct Sizing

Use a dish size appropriate to the amount of food you’re heating. Overfilling or underfilling can lead to uneven heating or potential breakage due to thermal stress.

How can you tell if a ceramic dish is microwave safe?

To determine if a ceramic dish is microwave safe, follow these steps:

Check for Labels or Symbols

Look for a “microwave-safe” label, symbol, or icon usually found on the bottom of the dish. These symbols often include a microwave silhouette or the words “microwave safe.”

Read the Manufacturer’s Instructions

If you have the original packaging or documentation, check for any notes on microwave safety. Manufacturers often specify if their products can be used in a microwave.

Perform the Water Test

  • Fill a microwave-safe glass measuring cup with water.
  • Place both the cup of water and the ceramic dish in the microwave. Ensure the dish is empty.
  • Microwave on high for about one minute.
  • After heating, touch the dish. If the dish is cool, while the water is hot, it’s likely microwave safe. If the dish is hot, it’s probably not safe for microwave use as it absorbs microwave energy.

Inspect for Metal

Check the dish for any metallic paint, trims, or decorations, as metal can spark or cause damage in a microwave.

Color and Glaze

Some glazes might not be microwave safe, especially if they’re not labeled. If you’re unsure about the glaze, it’s better to err on the side of caution.

Corning Ware in Other Cooking Methods

a) Stovetop Use

Older models like the Blue Cornflower Corning Ware, which often came with removable handles, are designed for both range and microwave use.

However, newer stoneware versions are not recommended for stovetop cooking. Always check the base of your piece if you’re unsure.

b) Oven Safety

All Corning Ware, except for Centura, can withstand oven temperatures up to 500°F, making it perfect for baking, roasting, or broiling. This high maximum temperature for Corning Ware allows for a wide range of cooking methods.

c) Microwave Browning Dish

If you have Corning Ware’s microwave browning dish, it’s designed to crisp food in the microwave and is also oven safe, enhancing your cooking options.

Can I bake bread in Corning Ware?

Yes, you can bake bread in Corning Ware. Corning Ware is made from Pyroceram, which provides excellent heat distribution and retention, making it suitable for baking bread.

Considerations

Even Heat Distribution

This helps in achieving a well-cooked loaf with a uniform crust.

Temperature Safety

Most Corning Ware can handle oven temperatures up to 500°F, which is more than sufficient for baking bread.

No Preheating Required

While some prefer preheating Dutch ovens for bread baking to create steam and enhance crust development, you can bake bread in Corning Ware without preheating the dish itself. However, preheating the oven is still necessary.

Lid Usage

If you use a lid, like with a casserole dish, it can help trap steam in the initial stages of baking, promoting oven spring and crust development.

Remember, though, that glass lids might have lower temperature limits than the dish itself (typically up to 350-450°F), so adjust accordingly or use a different type of lid for higher temperatures.

Shape and Size

Choose the right size of Corning Ware for your dough. The shape can also influence the final loaf shape; for example, round dishes for boules or oblong for traditional bread shapes.

Avoid Thermal Shock

Don’t place hot Corning Ware directly from the oven onto a cold surface; use a trivet or cooling rack to prevent cracking due to sudden temperature changes.

How do you remove scorch marks from Corning Ware?

Removing scorch marks from Corning Ware can be done through several methods, focusing on gentle yet effective cleaning techniques:

a) Baking Soda Paste

  • Mix a paste using baking soda and a little water. The consistency should be thick enough to adhere to the scorch marks.
  • Apply this paste to the scorch marks on your Corning Ware.
  • Let it Sit for about 30 minutes to an hour, allowing the baking soda to work on the stains.
  • Scrub gently with a non-abrasive sponge or soft cloth. If the marks are stubborn, use a plastic scrubbing pad but avoid anything too harsh that could scratch the surface.
  • Rinse well with warm water and dry.

b) Bar Keepers Friend

  • This is a popular cleaner for removing stains and scorch marks from various kitchen surfaces, including Corning Ware.
  • Sprinkle Bar Keepers Friend powder onto the wet surface where the scorch marks are.
  • Scrub with a damp non-abrasive sponge or cloth in a circular motion until the marks begin to fade.
  • Rinse thoroughly and dry.

c) Hydrogen Peroxide

  • For lighter scorch marks, hydrogen peroxide can be effective.
  • Mix equal parts of hydrogen peroxide and water.
  • Dab the solution onto the scorch marks with a cloth or sponge.
  • Let it Sit for a few minutes.
  • Rinse and dry. This method is particularly good for light stains and might need repeating for darker marks.

d) Vinegar Soak

  • Fill the scorched Corning Ware with enough white vinegar to cover the marks.
  • Soak for several hours or overnight. Vinegar can help dissolve burnt-on residues.
  • Scrub if necessary with a gentle scrubber after soaking.
  • Rinse and dry.

e) Dishwasher Method (for less severe marks)

  • If the marks are not too deep, placing the dish in the dishwasher might help, especially if you use a high-quality detergent designed for tough stains.

    Important Notes

    Avoid Abrasives

    Never use metal scouring pads or harsh abrasives that could damage the surface of your Corning Ware.

    Test First

    If you’re unsure about a method, test it on a small, inconspicuous area of the dish first to ensure it doesn’t harm the finish.

    Repeat if Necessary

    Some stains might require multiple treatments. Be patient and repeat the process as needed.
