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).
• Lead white: A historical white pigment (basic lead carbonate) now largely replaced due to toxicity.

Synonyms

• Zinc oxide pigment
• Flake white (Note: This can sometimes refer to a composite pigment, but historically was lead-based. In modern contexts, it may be a blend including zinc white.)

Notes on Meaning

This term refers exclusively to the pigment material. It does not describe the color white in a general sense. Its primary meaning is tied to its composition (zinc oxide) and its use as a coloring and protective agent in paints.
