CorningWare customers commonly need help identifying whether an older dish is safe for a conventional oven, determining whether a piece can be used on a stovetop, replacing a broken lid, reporting cracked stoneware, returning an online order, or filing a warranty claim. Because CorningWare has been sold in several materials and product lines over many decades, instructions for one piece should not automatically be applied to another.
For CorningWare product and warranty support, call Corelle Brands Consumer Care at 1-800-999-3436, email support@corellebrands.com, or submit the official online contact form.

CorningWare Is Operated by Corelle Brands
CorningWare consumer cookware and bakeware are operated by Corelle Brands LLC. Corelle Brands also markets products under names including Corelle, Pyrex, Visions, Chicago Cutlery, and Snapware.
The CORNINGWARE trademark is registered to Corning Incorporated and used under license by Corelle Brands. Corning Incorporated is a separate glass and materials-technology company and does not handle ordinary CorningWare cookware orders, replacement lids, returns, or consumer warranty claims.
Identify the Exact CorningWare Product Before Using It
CorningWare has been produced in different materials and forms, including:
- Current stoneware baking and casserole dishes
- CorningWare Stovetop glass-ceramic or Pyroceram cookware
- Vintage Corning Ware glass-ceramic cookware
- Microwave browning dishes
- Meal mugs and serving pieces
- Glass lids
- Plastic storage lids
- Portable dishes and carrying accessories
- Historic coffee percolators
Pieces with similar colors or patterns may have different heat limits. Do not rely only on the white color, French White shape, Blue Cornflower design, age, or CorningWare name.
Information That Helps Identify a CorningWare Piece
- Every word, number, or symbol on the bottom
- Model number
- Capacity
- Dimensions
- Pattern or color
- Whether the piece is stoneware or glass-ceramic
- Whether it has removable handles
- Glass, plastic, or glass-ceramic lid
- Approximate purchase date
- Country of manufacture
- Photographs from several angles
Do not use an unidentified piece on direct heat merely because another CorningWare product was designed for stovetop use.
Is Current CorningWare Stoneware Oven-Safe?
Many current CorningWare French White and French Colors stoneware baking dishes are designed for use in a preheated conventional or convection oven. Current product pages also commonly identify the dishes as safe for the microwave, refrigerator, freezer, and dishwasher.
Always verify the product page, bottom markings, packaging, and use instructions for the exact model.
Preheat the Oven First
Corelle Brands instructs users to preheat a conventional or convection oven before inserting qualifying CorningWare stoneware. Placing stoneware into an oven while it heats can expose the piece to uneven or unpredictable temperature changes.
Do Not Assume the Lid Has the Same Heat Limits
- Glass lid: May be approved for a preheated oven when the exact product instructions allow it.
- Plastic lid: Is generally intended for storage and microwave use when vented as instructed, not conventional-oven use.
- Vintage or unidentified lid: Should not be heated until it is positively identified.
Use a dry potholder or cloth when handling hot stoneware or glass lids.
Can CorningWare Be Used on a Stovetop?
Most current CorningWare French White and French Colors stoneware bakeware should not be used on a stovetop, open flame, grill, broiler, or another direct heat source.
Certain products specifically sold as CorningWare Stovetop or made from qualifying Pyroceram glass-ceramic were designed for uses that ordinary stoneware cannot tolerate. Their separate instructions and markings control.
Do not place a piece on a burner unless:
- The exact product is positively identified.
- The manufacturer’s instructions specifically authorize stovetop use.
- The piece is undamaged.
- The required heat, burner, liquid, and handling instructions are followed.
A stoneware dish can crack or shatter if exposed to direct stovetop heat.
Can CorningWare Be Used Under a Broiler?
Do not use current CorningWare stoneware or an ordinary glass lid under a broiler unless the exact instructions explicitly authorize it. A broiler produces intense direct heat that differs from a preheated conventional oven.
Do not place a glass lid:
- On a stovetop burner
- Under a broiler
- On a grill
- In a toaster oven
- Over an open flame
- On another direct heat source
Can CorningWare Go From the Freezer to the Oven?
Some current CorningWare product descriptions advertise freezer-to-preheated-oven use. However, customers should follow the exact model’s current instructions and avoid sudden temperature changes.
Never:
- Add cold liquid to a hot dish
- Place a hot dish on a wet or cold surface
- Handle hot stoneware with a wet cloth
- Place a hot lid in cold water
- Use a cracked or chipped dish
- Move an unidentified vintage piece between temperature extremes
When the instructions are unavailable, allow the product to change temperature gradually and ask Consumer Care for model-specific guidance.
Can a CorningWare Microwave Browning Dish Go in a Regular Oven?
Do not assume that a microwave browning dish is safe for a conventional oven. Microwave browning dishes may contain a special heat-absorbing surface and may have instructions that differ from ordinary CorningWare stoneware.
Before placing one in an oven:
- Locate the model number and bottom markings.
- Find the original manual or manufacturer instructions.
- Check for an oven-safe temperature statement.
- Confirm whether the lid or accessory is oven-safe.
- Contact Corelle Brands Consumer Care if the product cannot be identified.
Do not test an uncertain browning dish in the oven.
Is an F-5-B CorningWare Dish Oven-Safe?
The F-5-B marking has appeared on CorningWare French White-style pieces, but a model number alone may not establish the material, production period, lid type, or current condition of a specific dish.
Photograph:
- The complete bottom marking
- The entire dish
- The lid
- The side profile
- Any scratches, chips, cracks, or discoloration
Send those photographs to Consumer Care and ask for model-specific safety instructions. Do not rely on an online marketplace description or instructions for a different F-series item.
Loose CorningWare Glass-Lid Knob
Stop using a glass lid when its knob is loose, cracked, stripped, or separating. A lid can fall, shatter, spill hot food, or cause a burn if lifted by an insecure knob.
Do not:
- Continue tightening a stripped fastener
- Use an improvised screw or adhesive
- Use glue that is not specifically approved for the temperatures and food-contact conditions involved
- Lift a hot lid by a loose knob
- Use a cracked or chipped glass cover
Contact Consumer Care with the model number, lid measurements, photographs of the knob and attachment, purchase date, and receipt when available.
CorningWare Replacement Lids and Parts
Corelle.com sells replacement lids for selected current CorningWare models. Compatibility depends on the dish’s model, shape, capacity, and dimensions.
Before ordering a lid:
- Read the complete dish model number.
- Measure the opening.
- Confirm whether the dish is round, oval, square, or rectangular.
- Check whether the required lid is glass or plastic.
- Compare the replacement-lid model shown on the official product page.
- Confirm the lid’s microwave, dishwasher, freezer, and oven limitations.
A lid that appears to fit may still be unsafe if it is not designed for the dish.
Vintage Replacement Parts
Corelle Brands may no longer stock parts for discontinued cookware, percolators, detachable handles, portable sets, or older lid designs.
Use caution with secondhand parts. Confirm that a replacement:
- Was manufactured for the exact model
- Has no cracks, chips, corrosion, or stripped threads
- Is not part of a recall or corrective action
- Has not been altered
- Includes every required washer, band, fastener, or handle component
CorningWare Coffee Percolator Safety Warning
The U.S. Consumer Product Safety Commission and Corning Glass Works announced a major corrective action involving Corning Ware coffee percolators in 1979.
The CPSC reported that the handle and metal band on affected percolators could separate without warning from the white glass-ceramic pot. A separation while the pot contains hot liquid can cause severe burns.
Owners of an older CorningWare percolator should:
- Stop using it.
- Review the current CPSC recall and corrective-action information.
- Do not assume that a replacement element, handle, screw, band, or cord makes the pot safe.
- Do not test the pot with boiling water.
- Use care when disposing of it.
A seller’s statement that a vintage percolator is collectible, restored, tested, or working does not override the CPSC safety guidance.
Stop Using Damaged CorningWare
Stop using a CorningWare dish or lid that is:
- Cracked
- Chipped
- Severely scratched
- Deeply crazed
- Loose at a handle or knob
- Damaged by impact
- Warped
- Previously repaired
- Leaking
- Damaged by direct heat
Glass and stoneware can retain damage from a drop or hard impact and later break without an obvious new cause.
If a dish breaks, use care when collecting sharp pieces. Keep children and pets away and do not place loose shards where they could injure sanitation workers.

CorningWare Customer Service Reviews and Complaints

- A question about using a microwave browning dish in a conventional oven
- A question about whether an F-5-B casserole was oven-safe
- A loose lid-knob complaint involving French White stoneware
- A request for a deeper Corelle plate, including praise for Corelle’s weight, durability, and price
