Cadmium sulphide glass

Refers to a type of glass that became popular in the 19th century. It is usually opaque and is characterized by a lime-yellow or lemon-yellow color that is caused by the presence of cadmium sulfide in the glass mixture. Selenium is sometimes added to the mixture to create orange or bright red glass. It is not related to "sulphides (glass)," which is glass characterized by the insertion of a carved object into clear glass.
