History

Produced during the late 19th and early 20th centuries, turquoise opaline glass—often referred to as "opaline bleu"—was a signature style of French glassworks such as Portieux Vallerysthal. These pieces combined classical revival forms with vibrant, saturated colors to appeal to the Victorian and Belle Époque taste for colorful, decorative table settings. Today, these distinctive turquoise pressed-glass comports are highly collectible for their striking color and elegant neoclassical proportions.
