Vicenza earth is a buff white or tan-colored natural mineral with a subtle, warm hue and low opacity. Use it as a useful glazing color to impart warmth to cooler tones. It also provides a delicate cloudiness that can help to soften focus and articulate a sense of space. Use Vicenza earth with heavy pigments to prevent separation and to give colors a short consistency.Origin and History
Vicenza earth was identified in medieval Italian porcelain. The Medici produced soft-paste porcelain, which has a different composition and is fired at lower temperatures than hard-paste porcelain. The clay used, from the Italian city of Vicenza, contains some kaolin, an essential ingredient in genuine Chinese porcelain.Source
