Why Does the Glass on the Electric Cooktop Look Green?

On the "true color" white or bisque smoothtop cooking surface, the glass will have a pinkish-red glow while the element is on. It will glow green when the burner is turned off and the element/glass is cooling down. The white or bisque color will return when the glass has cooled. These color changes are due to the properties of the glass itself and are considered normal; service is not required for color change conditions.
