WHAT COLOR IS CORELLE WINTER FROST?

Corelle Winter Frost is exclusively available in a pure white colorway.

The specific white formulation used in the Winter Frost collection features what Corelle describes as a “bright white” finish rather than an off-white or cream tone.

Colorimetric analysis would place it at approximately 95% on the whiteness index used in ceramic manufacturing.

This pure white finish is achieved through the material composition of the Vitrelle glass rather than through surface glazing, resulting in color consistency throughout the material rather than just on the surface.

IS CORELLE WINTER FROST WHITE LEAD-FREE?

According to Corelle’s published material safety data sheets and third-party testing verification, the Winter Frost collection is 100% lead and cadmium-free.

This compliance exceeds the FDA requirements for food contact surfaces, which allow for trace amounts of lead in ceramic glazes (up to 0.5 μg/ml), but Corelle’s manufacturing process eliminates these heavy metals.

Independent laboratory testing by organizations such as the Ecology Center has verified these claims through XRF (X-ray fluorescence) testing methodology, which can detect trace elements in consumer products.
