ANSWERS

01. Why are Corelle® products so durable?

Corelle® products are created using a special glass lamination process that thermally bonds two clear "skin" layers of glass to a white or beige "core" layer. This proprietary technique is unique to Corelle® - in fact, we invented it!

02. Do Corelle® products contain lead?

All Corelle® stoneware products and glazes are made of clay-based materials and glazes used throughout the industry. Decorations, if present, are made from low-lead enamels and fired at temperatures exceeding 1000 degrees F, which binds any heavy metals both physically and chemically so that their release is minimized.

The current limit for presence of leachable lead in order to satisfy certain requirements is no more than 0.100 ppm (1 tenth of one part per million) when obtained under test conditions. At no time have World Kitchens results exceeded levels permissible under the guidelines mentioned above (which are believed to be the most stringent in the world).

Tests for the presence of heavy metals are conducted for World Kitchen by internationally certified, third-party laboratories under strict conditions, by trained technicians, and using atomic absorption spectrophotometry analysis following carefully monitored preparation. These steps are necessary to minimize any possibility of contamination or false reading during preparation, testing or analysis.

05. What's the difference between Corelle® and Corelle Coordinates® Festiva™ glass dinnerware

Festiva™ glass dinnerware, a coordinating accent line for Corelle® dinnerware, is manufactured by World Kitchen sister brand Pyrex. Made of transparent soda lime glass, Festiva™ dinnerware does not have the same durability associated with Corelle® dinnerware, but it does offer freezer-to-oven/microwave-to-table versatility.

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

The glass lamination process used for Corelle® ware is ideal for making plates and bowls, but it unfortunately does not work well for cup or mug shapes. That's why we offer stoneware mugs with every Corelle® dinnerware set.

16. I dropped my Corelle® dinnerware, and it shattered. I thought it was break and chip resistant. Why did this happen?

Although Corelle® dinnerware is made of Vitrelle® glass, known for its strength and durability, all glass is breakable. We offer a three-year warranty against breakage, chipping, and staining under normal household use. This warranty does not cover accidental breakage.

17. Why does the surface of my Corelle® product look "pebbly"?

Before Corelle® products leave the factory, they are sprayed with an organic, non-toxic coating to help prevent damage during shipping. Wash your Corelle® ware with detergent and hot water before using it, or run it through a dishwasher cycle.

18. What causes the gray lines or marks on my Corelle® dinnerware?

Although Corelle® dinnerware is made of Vitrelle® glass, known for its strength and durability, metal utensils, silverware, metal dishwasher racks, metal cleaning pads, and stainless steel sinks may cause gray markings. These gray marks can be removed with a non-abrasive cleaner such as Zud®.

19. Why are there stains on my Corelle® cups or mugs?

Each community's water supply is slightly different. That means Corelle® cups may stain due to mineral deposits from use of untreated water over time. The oils from coffee or tea may adhere to the sides of the cups because of the mineral deposits/residue in the water. These stains can be removed with a nonabrasive cleaner such as Bon-Ami®. Or, fill the cup 1/4 full with vinegar and clean with a paper towel. Rinse and dry thoroughly. DO NOT attempt to use bleach to clean the stains, as this will only lighten them. Stains may reappear if the water used for cleaning is left untreated.

20. Why are there rust or brownish marks on my Corelle® ware?

No worry - rust-colored marks can be caused by iron deposits in your water supply or even by exposed metal parts in your dishwasher or drying rack. Try a nonabrasive cleaner such as Bar Keeper's Friend® or Zud®.
