What characterizes a flat finish used on casket exteriors?

A flat finish on casket exteriors is characterized by a dull, lusterless surface, which is what distinguishes it from other types of finishes that may have a reflective quality. This kind of finish is typically preferred in certain design contexts where a more subdued, understated aesthetic is desired.

Flat finishes do not reflect light, creating a soft appearance that can evoke a sense of calm and serenity, which is often appropriate for caskets. The absence of shine emphasizes the material's color and texture without the distraction of gloss. This is particularly significant when caskets are chosen for memorial services, as the focus is intended to be more on honoring the individual rather than showcasing opulence.

In contrast, other finishes like glossy surfaces or shiny appearances are designed to reflect light and create a vibrant, eye-catching look, which is not what a flat finish aims to achieve. Additionally, patterned textures might add visual interest but would also diverge from the smooth, non-reflective quality that defines a flat finish.
