Marble Dust - Poudre de marbre

Marble dust is a solid waste material (by-product) generated from the processing of white marble from the Eastern Pyrenees of South France. The ground calcium carbonate is characterized by its high brightness and chemical purity. Marble Dust is used as a natural mineral pigment or as a natural mineral filler/ texture enhancer in the preparation of casein paints or lime, whitewash, coating, stucco, and cement. The addition of Marble Dust to other substances does not affect the original colour of the substance so it is a great way to enhance texture or be used as a filler with no impact to colour. Marble Dust is made from calcium carbonate and is white in colour.

The granularities of Marble dust can vary from 0 to 400 microns. Color-Rare has different granularities of Marble Dust available in 1 kg bags:

How to Mix Marble Dust into Paint or other base products:

Start with a small amount of Marble dust and gradually mix it into your paint or other base product.  Add more dust to the mixture to make it thick and pasty. If the mixture is too thick, add more paint/ other base to thin it out. Continue experimenting with adding marble dust to the mixture until you are happy with the consistency.
