Whiting is basically ground CHALK. It is made of mostly calcium carbonate and mined in various parts of the world.
Whiting is used in a wide variety of industries. In the painting industry, it is used in most paint products as a thickener, in putty products, and as a polishing compound for glass, ceramics, and metals such as silver and brass.
In decorative painting, it has many valuable uses:
- As a thickener for paint, glaze, varnish, etc
- It thickens without adding color. Don’t be fooled by the name, there isn’t any white color.
- It is an effective matting agent (but talc powder is better)
- Used to polish a surface
- Great to use for cleaning really dirty brushes (as a scrub)
- Fantastic at “degreasing” or preparing an oil basecoat for a water glaze
