|Wollastonite produces a more uneven texture than Ground Quartz, therefore giving a ground for harder pastels (use Ground Quartz for soft pastels). Wollastonite is ideal for acrylic paints due to its alkaline properties. Add to Gloss Varnish and Gloss Medium, Gesso, Low Viscosity Gesso or MM28 Polymer Satin Varnish (water-based) to create texture in paintings on canvas.
Mix up to 50% Wollastonite to background paint to create a superb textured surface for pastels and charcoal. 50ml bottle. Display image show Wollastonite mixed with blue paint.
