Description

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

Vicenza earth comes from Vicenza, Italy as a buff or tan-colored kaolin.

Permanence and Compatibility

Vicenza earth is unaffected by dilute acids and alkalis. It is compatible with all pigments and in all vehicles.

Oil Absorption and Grinding

Vicenza earth absorbs 30 to 40 grams of oil per 100 grams of pigment. It readily mixes with oil and water to form a smooth paste.

Toxicity

Vicenza earth is not considered to be toxic, however, care should be used in handling the dry powder pigment to avoid breathing the dust.
