Talc 1kg

SKU: NAP-510-13TAL1K

Brilliant white, fine talc for making grounds, paint and pastels. Our talc is dry ground from natural ores in Montana. Use as an additive to make grounds and for adding texture and body to paints. Add to oil colors and mediums to create textural and bodying qualities to oil paint without affecting the color. Chalk has little color in drying oil, so it can be added to oil paint without affecting the tint of the color.
