Definition
Noun: A white pigment used in house paints and other coatings, consisting primarily of zinc oxide. It is valued for its opacity, whiteness, and resistance to ultraviolet light.
Usage
"Zinc white" is a technical term used primarily in the fields of art, paint manufacturing, and industrial coatings. It refers specifically to the pigment itself, not to a can of paint. It is often compared to other white pigments like titanium white or lead white.
Examples
- The artist preferred zinc white for its cool, transparent qualities in glazes.
- This primer contains zinc white, which helps protect the wood from mildew.
- Historically, zinc white replaced the more toxic lead white in many applications.
Advanced Usage
- In Art Conservation: The use of zinc white in historical paintings is studied to understand an artist's technique and for restoration purposes.
- Technical Specification: In industrial contexts, the purity and particle size of zinc white are critical for its performance in a final product.
Variants and Related Words
- Zinc oxide (ZnO): The chemical compound that constitutes zinc white.
- Chinese white: A term sometimes used for high-grade zinc white, particularly in watercolor paints.
- Titanium white: A different, more opaque white pigment (titanium dioxide).

Notes on Meaning
