Description

The Basic Grounds Set contains eight different fillers (extender pigments) in a boxed set that is an excellent introduction to making your own grounds and mediums and as a great gift for the art student. The set is especially useful for exploring the function and behavior of different fillers in grounds and painting mediums.

Eight natural minerals are included in this set to introduce you to extender pigments and their function in grounds and painting mediums. The set includes 4 vol oz. jars each of:

Set Contents

Bright white, fine talc for making grounds, paint, and pastels. Our talc is dry ground from an extensive deposit of high-quality Montana talc ore. It has low oil absorption in oil and solvent-borne paint and primers. The chemically inert nature of talc improves the weatherability of paint. The hydrophobic nature of talc surface contributes to the rheological (flow) properties (anti-sag, leveling, and brush ability) and functional properties (gloss and sheen control) of paint.

A natural mineral imported from Bologna, Italy composed of monoclinic prismatic crystals of hydrated calcium sulfate-carbonate. This is finely-ground whiting that combines the advantages of chalk (calcium carbonate) and gypsum (calcium sulfate) for making painting and gilding grounds that are brilliant white.
The finest whiting for making brilliant white chalk grounds. Our whiting is dry ground from limestone deposits in the Lucerne Valley, California. Dry grinding limestone reduces it to a powder without destroying its particle structure, which is important in making strong chalk grounds and providing tooth on the surface of the grounds. The larger particle size of our chalk (when compared to precipitated chalk) keeps oil absorption low, which is ideal when adding it to oil paint and mediums. In painting grounds, it makes a durable surface with texture for egg and casein tempera, distemper, encaustic, and oil paint. The set includes 4 vol oz. jars each of Fine and Extra Fine Chalk.
Alabaster (also called satin spar) is a natural crystalline mineral of hydrated calcium sulfate mined near Volterra (between Florence and Sienna), Italy. Softer than chalk (3 Mohs scale of mineral hardness), its hardness of 1.5 to 2 makes a soft white gesso that is easier to polish to a smooth finish for gilding bases and painting grounds. Calcite or chalk, being a carbonate, effervesces on exposure to acids, whereas gypsum alabaster, when so treated, remains practically unaffected.
This is a high purity, natural crystalline silica that comes from quartz quarries in Oklahoma. It is a fine ground silica sand that is inherently inert, white, bright and is at least 99.2% silicon dioxide. Special processing assures a controlled particle size distribution, which eliminates excessively coarse and fine particles. These properties, combined with its inertness and low cost, make silica an excellent filler and extender for paint.
Nepheline syenite is a micronized functional filler and extender used as a performance enhancer in a broad range of paints, coatings, adhesives, sealants, and inks. Excellent brightness, tint retention, and weatherability can be achieved in paints. Improved color, sheen uniformity, chemical and stain resistance, and durability result when it is used in interior paint formulations. It is easily dispersed in all conventional vehicle systems, and low oil absorption permits high loadings in adhesives, sealants, and aqueous and alkyd-based paints.
Wollastonite is a calcium metasilicate mineral that exhibits lower viscosity of paint than is indicated by its oil absorption value. The low oil absorption characteristic of wollastonite enables you to reduce raw material costs by the replacement of the vehicle. The relatively high pH (10–11) of wollastonite is particularly useful in maintaining the desired alkaline pH level of water-based paints and preventing the early rusting of water-based coatings. Wollastonite is an excellent extender pigment for powder coatings as well as solvent-based and waterborne paints.
