    Venetian and Marmarino plasters are a mixture of Lime putty and Marble dust, with small quantities of natural oils and waxes which are not designated as harmful materials. Powdered pigments are added for colour. Lime putty is a gel of
    Calcium Hydroxide Ca(OH)2 and trace quantities of calcium carbonate.
    Hazardous Ingredient - calcium hydroxide.

    3. Hazard Identification
    Irritating to eyes and skin. Risk of serious damage to eyes. May cause burns.

     4. First Aid Measures
    Skin Contact - Remove contaminated clothing. Wash immediately with plenty of water.
