Venetian Red is a natural earth containing clay tinted by iron oxide that is a warm red with cold red undertones, giving beautiful pink colors in tints with white and thinned applications. Like many Italian red ochers, our Venetian red contains at least 20% iron oxide and calcium dihydrate (gypsum). Venetian red is obtained from iron ore deposits nesr Verona in the Veneto region, Italy.

Venetian Red is an ocher that has been used as a pigment since prehistoric times and is perhaps the most widely used pigment for artists' paints.
SourceVenetian red is a red ocher obtained in the vicinity of Venice. Red ochers are natural earths containing clay tinted by iron oxide and are composed of a naturally calcined form of and traces of gypsum (calcium sulfate) and calcite (calcium carbonate). Hematite is a mineral composed of iron oxide minerals (Fe2O3) that occur as natural earth. Depending upon the content of iron oxide and other minerals, the color of red ocher varies from deep red to brownish red. Red iron oxide minerals, such as hematite, are found worldwide and have been used as pigments since prehistory.
Permanence and CompatibilityRed ochers are among the most permanent colors on the artist's palette. It is compatible with all other pigments and can be used with good results in all mediums.
Oil Absorption and GrindingRed ochers absorb a medium amount of oil, which may slow the drying of oil paint, but because iron oxide is a drier in oil, it dries moderately fast and forms an excellent film.
ToxicityRed ochers are not considered toxic, but care should be used in handling the dry powder pigment to avoid inhaling the dust.
