Which type of finish on casket exteriors is characterized by a dull and lusterless surface?

A flat finish on casket exteriors is recognized for its dull and lusterless surface. This type of finish minimizes reflections and provides a subdued appearance, which can be particularly suitable for those seeking a more understated and traditional look in a casket. Flat finishes often have a soft texture and do not emit shine, making them distinct from other finishes that may reflect light and have a glossy or semi-gloss appearance.

In contrast, gloss finishes are designed to be shiny and reflective, enhancing colors and patterns on the surface. Sprayed finishes can vary widely, potentially leading to either matte or glossy results depending on the type of spray technique and finish used. A matte finish, while similar to flat in its lack of shine, typically has a slightly more textured surface yet is often used interchangeably with flat to describe finishes that do not reflect light. Thus, while matte can also refer to a non-shiny finish, the most precise characterization of a dull and lusterless casket exterior is identified as flat.
