shellac wax
Definition
Noun A hard, brittle wax that is a natural component of shellac but is separated from it because it does not dissolve in alcohol. It is a byproduct of processing lac resin.
Usage
"Shellac wax" is used as a specific term in chemistry, manufacturing, and restoration to refer to this distinct, insoluble material. * The conservator removed the old shellac wax from the antique furniture before reapplying a fresh finish. * During purification, the shellac wax is filtered out, leaving a more refined shellac solution.
Advanced Usage
- Industrial Separation: The process of separating shellac wax from shellac is based on its insolubility in ethanol, a key property for producing dewaxed shellac.
- Material Property: In technical contexts, "shellac wax" is noted for its high melting point and hardness compared to other natural waxes.
Variants and Related Words
- Shellac (noun): The resinous secretion of the lac insect, used to make varnish, which contains shellac wax before processing.
- Dewaxed shellac (noun): Shellac that has had the shellac wax removed, resulting in a clearer, more consistent product.
Synonyms
- Lac wax (This is a direct synonym often used in technical literature.)
Notes on Meaning
This term has a single, precise technical meaning. It refers specifically to the wax fraction isolated from crude shellac resin, not to shellac itself or to any other type of wax.
Noun
-
