We try to create dinnerware designs with lasting appeal however, unfortunately, some patterns lose their popularity over time. When this happens, we discontinue the pattern.

If you'd love to see your patterned brought back to life or reimagined, drop us a line! We'd love to hear your feedback.

What is the coating on my new Corelle® Vitrelle glass dinnerware?

Before Corelle® Vitrelle® glass dinnerware leaves the factory, they are sprayed with an organic, non-toxic silicone based coating to help prevent damage during shipping.

With any Corelle® dinnerware we recommend washing it with detergent and hot water before using, or runing it through a dishwasher cycle.

Are Corelle® products lead-free?

We are very proud of our Corelle products, which are made of Vitrelle, a tempered glass consisting of glass laminated into three layers. Corelle was first introduced by Corning over 50 years ago and in 2000 started to be manufactured by the company known today as Instant Brands. All Corelle products meet the safety standards at the time of manufacturing.

As manufacturing and regulatory practices have evolved, so have Corelle products. We routinely test Corelle products for lead and cadmium contents at internationally recognized, third-party testing laboratories. This testing confirms that our products comply with applicable federal and state safety regulations.

Corelle dinnerware has come in many different patterns over the years since it was first introduced by Corning and continued with Instant Brands, and many vintage/legacy pieces have become cherished collectors’ items. Before 2000, and before tighter lead content safety regulations, a small amount of lead was an ingredient in the decorating process of many household products. Instant Brands has conducted additional testing with an outside laboratory to determine whether vintage Corelle products made before 2000 comply with today’s consumer [your] expectations as to safety and whether it’s ok to use them as everyday dinnerware. The Company selected multiple patterns of vintage Corelle products, dating back to 1978 for testing.

The food surface contact testing was designed to identify whether any small amount of lead that may have existed in pre-2000 manufactured Corelle product leaches from the product in amounts above today’s acceptable lead-safety regulations. The small amount of lead used in decorations pre-2000 was encapsulated in glass before and after the decoration was applied to product and fired to above 750C. The Corelle manufacturing process has always encapsulated decoration in glass, using extremely high processing temperatures to ensure the glass decorations are sealed, which prevents food contact and intentionally decreases the extent of any lead migration to food.

The testing confirms that the vintage products tested comply with current FDA lead-safety regulations – so feel free to use them for everyday dinnerware.

Are Corelle® dinnerware products microwave safe? My plates and bowls become hot in the microwave.

Yes, Corelle®Vitrelle® glass dinnerware is microwave safe when used in accordance with the safety and usage Instructions that came with your product at the time of purchase. Be sure to use a dry pot holder when handling hot glass.

What causes the gray lines or marks on my Corelle® Vitrelle® glass dinnerware?

These gray marks can be removed with a non-abrasive cleaner. We use Bar Keeper's Friend® in our test kitchen, because it works and lends itself to so many other uses!

Why are my Corelle® mugs made from a different material than my plates and bowls?

These rust marks can be removed with a non-abrasive cleaner. We use Bar Keeper's Friend® in our test kitchen, because it works and lends itself to so many other uses!

The coating is easily removed by washing the dishes in hot soapy water.

My Corelle® MilkGlass® dishes have a slight variation is shape from plate to plate and bowl to bowl. Is this normal?

This variation gives the dinnerware its characteristic fun and stylish design that is perfect for everyday meals and entertaining at home. 

Can I recycle my Corelle® Vitrelle® glass and MilkGlass® dinnerware?

The manufacturing process for making Corelle® Vitrelle® glass dinnerware produces strong, lightweight tableware. However, there may be some visible variance on the rims of the items that is noticeable when the dishes are stacked. Corelle dinnerware may appear to be warped because they fit so snugly together; repositioning them in the cabinet may make it less noticeable. This variance does not affect the performance of the product.

Provide an answer to the question here, with as much detail as possible to help your customers.

What are the benefits of Pyrex® brand products?

A kitchen staple for more than 90 years, Pyrex® glass bakeware can handle almost every job in the kitchen and is versatile enough to use in the refrigerator, freezer, oven, microwave, dishwasher and on the table. 

Are Pyrex® products covered by a warranty?

Yes - for details, click here to visit our product warranty section.

What is the maximum oven temperature for Pyrex®?

Pyrex® glass bakeware is designed for use in a completely preheated conventional or convection oven at any temperature that is called for in a baking recipe, provided you follow the Pyrex® Safety and Usage Instructions. Remember that Pyrex® glass bakeware is not to be used with any direct heat source such as on the stovetop or under the broiler. Failure to follow the safeguards and instructions may result in personal injury and/or property damage. Visit our Product Warranties page.

Which is better Soda lime or Borosilicate glass?

As we produce both soda-lime and borosilicate glass this means that both materials meet our high-quality standards with over 100+ years of manufacturing experience. 
Both Soda Lime and Borosilicate are safe for use at any temperature called for in kitchen cooking given the Safety and Usage instructions are followed.

Why does my Pyrex® baking dish have a raised center?

The raised area in the center of the Pyrex® dish is called a crown and creates a more stable bottom for the dish. If the dish was completely flat on the bottom, it would allow the dish to spin around on a countertop, table, etc. Crowning the inside of the dish makes the outside edges a point of contact and provides a more stable surface for the dish.

Why are the dishes in my set different colors/tints?

You may notice that some of our Pyrex® brand glassware has a slight tint of green or blue hue to the dish. It is not a coating or added color. It comes from the raw materials in the glass itself. The blue comes from adding cobalt to the raw materials. This does not affect the performance of the dish; it is purely cosmetic.

Are Pyrex® glass products diswasher safe?

YES - The dishwasher must be properly loaded to avoid items from making contact during the cycle. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.  Visit our Product Warranties page.

Failure to follow the safeguards and instructions may result in personal injury and/or property damage.  Visit our Product Warranties page.

If my food becomes dry, can I add liquid to the dish?

NO - Adding liquid to hot glass may compromise the product’s strength, potentially resulting in breakage. Avoid sudden temperature changes. Prior to putting the dish in the oven, add enough liquid to cover the entire bottom of the dish for any foods that may release liquid while cooking such as meats and vegetables. Failure to follow the safeguards and instructions may result in personal injury and/or property damage.  Visit our Product Warranties page.

How do I find the model number for a replacement cover?

To identify which cover, refer to the bottom of your bowl, dish, or container. Look for the volume (cup or quart) and the model number which should start with a 2, 3, 7, or 8. Once you have this information, please visit our website.

 

Choose the cover that matches the amount of cups or quarts the dish holds. (Hint: Storage containers will be in cups. Mixing bowls and baking dishes will be in quarts).

The hot water will expand the cover so that it fits and forms to the dish. Failure to follow the safeguards and instructions may result in personal injury and/or property damage. Visit our Product Warranties page.

How do I get lingering food odors out of a cover?

We recommend soaking in white vinegar overnight then washing with hot soapy water. Please note that as plastic is porous, this method may not remove all of the odor and it may just take time. We do not recommend storing foods with strong odors, such as onion or garlic, in the dish due to this reason.

My cover has warped. Can I straighten it?

NO - Once a cover has warped, there is no way to reshape it. If the cover is within our two-year warranty period, please contact us. Failure to follow the safeguards and instructions may result in personal injury and/or property damage. Visit our Product Warranties page.

Frequently asked questions

Who do I contact for questions or concerns about products?

Email us via our online contact form. We strive to answer your questions within one business day. See our contact information for international inquiries.

During cooking, food sticks to my cookware. How can I prevent this?

Take the chill off foods before cooking. Remove foods from the refrigerator and allow them to warm slightly (10-15 minutes).

Preheat your pan over medium heat. Test the edge of the pan by tapping it lightly and quickly with your fingers. If it's hot to the touch, it's ready for cooking. Then add about 1 tablespoon of oil or butter and let that get hot. You should hear a sizzle upon placing your food items in the pan.

Turn down the heat! Keep heat at medium to medium-high for frying or sautéing. For simmering and longer stovetop cooking, use low heat. One way to test your pan to see if it's too hot is to do the butter test. Unpeel a stick of butter and coat the inside of your preheated pan. If the butter foams and turns brown, the pan is too hot.

Keep your cookware thoroughly clean, inside and out, for performance as well as appearance. Residue from previous cooking is a common cause of sticking, even on nonstick surfaces. Sometimes hot soapy water does not remove all the oils that build up over time. We recommend cleaning pans periodically with a non-abrasive cleanser.

Condition new pans before use by wiping the surface with a thin coating of shortening or oil. Use medium to low heat for best cooking results. Extremely high temperatures can cause discoloration and shorten the life of any nonstick finish. If higher temperatures are necessary, preheat the pan on medium for a few minutes. Nylon, plastic, wooden or rubber utensils are preferred. Metal utensils may be used with care, but don't cut in the pan.

Dishwashers will not affect the nonstick coating but may affect handles or knobs. Recondition the coating after dishwasher washing by wiping with thin coating of shortening or oil.

How should I clean my kitchenware products?

Most of our kitchenware products are dishwasher safe. Refer to packaging instructions to verify that an item is labeled as dishwasher safe. Some exceptions include gadgets with gearing such as can openers, items inappropriate for submerging in water such as scales or dial timers, any items made of wood, and all battery-operated items such as digital timers and thermometers. For best results, or if in question, hand wash items with a soapy cloth or sponge and dry immediately. Dishwashing tends to shorten the life of kitchenware products due to heat and aggressive detergents.

How do I remove a stain from my plastic cover?

We cannot guarantee that you will be able to completely remove a stain. Soak the lid in a mixture of water and vinegar and/or try to use a non-abrasive cleanser to lighten stains.

How can I prevent stains on my plastic covers?

To prevent staining, we recommend not filling the dish to the rim/top. Leaving about a 1/2"" to 1"" gap will allow room for foods to expand when cooled or frozen, thus preventing them from coming in to contact with the plastic cover. Adding a layer of plastic wrap, wax, or parchment paper before placing the plastic cover, can also help protect the plastic cover.

Why are there gray marks on my CorningWare® casseroles, and how can I remove them?

The gray marks are most likely from metal utensils, which should not be used with CorningWare® casserole dishes. Instead use wooden, nylon or plastic utensils. To loosen food before cleaning, allow the bakeware to soak and then use only plastic or nylon cleaning pads with nonabrasive cleansers. A soft sponge with a non-abrasive cleaner should remove the gray marks. 

What are the advantages of owning the new French White® products?

The five new shapes - each with new handle designs for safety and comfort - are ideal for complementing your current French White® collection or starting a new one. The glass covers provide a contemporary look, and the plastic covers are vented with an inner seal to optimize freshness. The new design eliminates areas where food can become trapped, allowing room for fingers to easily wipe away remnants. Plus, the new pieces are all dishwasher safe. 

Why are the new French White® plastic covers preferred over plastic wrap, aluminum foil or plastic containers?

The new gasket-sealing plastic covers feature a unique design to help keep your stored food as fresh as possible. Simply press down the cover and close the steam vent to create a tight seal. Later, simply pop the steam vent to open the seal.

Are Chicago Cutlery products covered by a warranty?

Chicago Cutlery® knives are warranted to be free of defects in material &workmanship under normal household use for the lifetime of the product. 

How should I sharpen fine-edge Chicago Cutlery® knives?

Sharp knives are safer than dull ones because dull knives require more pressure for cutting, which can result in slipping. 1. Hold sharpening steel point down on flat stable surface like table or cutting board 2. Angle the knife blade so that it is approximately 15 degrees from the sharpening steel 3. Pull the knife down and across the sharpening steel in a slight arc, pulling the knife handle toward you. Stroke the entire blade edge from base to tip. 4. Repeat on the other side of the steel. 5. Repeat steps 3 &4 three to five times, alternating the right and left side of the cutting edge. Knives should be sharpened after every couple uses for maximum performance. Use a scouring powder to clean and remove metal particles from your sharpening steel. After cleaning the steel, rinse it with water, dry it thoroughly and store it in a dry place. 

How should I clean Chicago Cutlery knives?

For best results, hand wash your knives with a soapy cloth and dry immediately. Soaking wood-handled knives in water can remove the natural oils from the handles. Dishwashing may cause banging against other dishes that can nick the edges. Additionally, the heat and detergent may have a corrosive effect on the handles. 

How should I store Chicago Cutlery knives?

Sharp knives should never be stored loose in a drawer because contact with hard objects can dull the blade, and reaching into a knife drawer can be very dangerous. We recommend storing your knives in a hardwood block for safety and convenience. Many Chicago Cutlery® sets include a hardwood block for storage. Empty Chicago Cutlery® hardwood blocks are also available at many retailers. 

What's the difference between stamped & forged blades?

Stamped knives are punched out of a single sheet of steel, resulting in thin, light blades. Forged knives are made from one piece of steel that is heated until soft then pounded into shape with a hammer. Forged knives are strong and heavy with a bolster (located where the blade meets the handle) for safety and balance. Chicago Cutlery offers a wide variety of knives with both stamped and forged blades. 

Where can I buy commercial-grade knives?

Commercial-grade knives are available through the following distributors: 

  •    Gamco 
  •    Hantover Bunzl-Koch Supplies 
  •    Memco Southland Industrial Supply 

Should Snapware® food storage containers be washed before use?

Yes, we recommend washing all containers before storing food in them. Please follow the directions that came with your container or read the Use & Care Instructions. 

Are Snapware® products BPA free?

Yes, every product that Snapware® currently sells is completely free of bisphenol-A (BPA). Snapware is committed to providing customers with safe, high quality and innovative storage containers, and removing BPA from all products is an important part of doing just that. Recently there has been much debate over the safety of BPA, which is a component of polycarbonate used in many plastics. BPA can potentially leach from containers when heated (via microwave or other methods), ultimately creating a safety risk when in contact with food. Due to these potential hazards, Snapware's extensive product lines are manufactured entirely without the use of BPA. We back our BPA-free claim with continuous material testing conducted by an internationally recognized independent lab. For additional details on BPA, visit https://www.factsonplastic.com/.

How can I remove the product barcode sticker?
