Stunning colors have long been the signature of Fenton's glass pieces. The company uses special ingredients - such as gold, manganese, and cobalt - to achieve its rich hues. In addition to elegant colors, Fenton's handpainted pieces are prized for their artistic detail. The company's team of highly trained artists renders designs with a mixture of enamel paint and finely crushed glass. The pieces are then exposed to extremely high heat to fuse the paint to the glass.
