Things You'll Need
Instructions
Research the seller before buying a bowl advertised as a Corelle bowl. Contact Corelle's Customer Care Center at (800) 999-3436 or online to verify that the retailer is an official seller of Corelle products.
Flip the bowl over and examine the bottom of the bowl for markings indicating it's a genuine Corelle bowl. Use a magnifying glass if necessary to assist your examination. Look for the words "Corelle," "Livingware," "Vive," "Impressions," "CorellePro" or "Square" as an indication that the bowl is an official Corelle bowl.
Compare the colors, design and pattern of the bowl against Corelle's online display of discontinued patterns if the seller is advertising a discontinued piece of Corelle dinnerware.
Look for a new Corelle serving bowl at an authorized Corelle retailer if you are trying to identify a new, unopened and packaged Corelle serving bowl. Write down the pattern name and style number located on the back of the packaging. Call Corelle's customer service line if you have any concerns about the legitimacy of the bowl.
