Marble Powder

Description:

Marble Powder is the finest marble dust for making brilliant white grounds. Our whiting is dry ground from marble deposits in the United States. Dry grinding reduces it to a powder without destroying its particle structure, which is important in making strong grounds and providing tooth on the surface of the grounds. The low surface area of our marble (when compared to precipitate chalk) keeps oil absorption low, which is ideal when adding it to paint and painting mediums. In painting grounds, it makes a durable surface with the tooth for egg and casein tempera, distemper, encaustic, oil paint, and watercolors.

Both limestone and marble are calcium carbonate (CaCO3), which is also the composition of the mineral calcite. Marble is a metamorphic rock composed of recrystallized calcite. The metamorphism of limestone causes the calcite grains to grow in size and to interlock with one another. The result is that marble is noticeably more dense and harder than limestone. Limestone forms under deep marine conditions from the gradual accumulation of minute calcite plates (coccoliths) shed from micro-organisms called coccolithophores and hence contains invertebrate fossils. However, these fossils are almost always destroyed by the metamorphic changes that convert limestone to marble.

Add to paint and mediums to create textural and bodying qualities to paint without affecting the color. Marble dust has a little color in drying oils, so it can be added to oil paint without affecting the tint of the color.
