Physical properties

Hardness: Approx 2-3 (Mohs scale); Color: Slate Gray; Luster: Matte textured; Structure: Amorphous (non-crystalline); Specific Gravity: 1.0 - 1.2

Formation & geological history

Injection molding process; modern industrial era (late 20th century). Formed through chemical polymerization and thermal processing.

Uses & applications

Automotive interior trim (glove box door), industrial enclosures, and consumer electronics housings.

Geological facts

This material is designed to be impact-resistant and heat-stable for vehicle interiors. It shows signs of surface abrasion and typical 'interior grime' from automotive use.

Field identification & locations

Identify in the field by its textured pebble-grain pattern, lightweight feel, and lack of coldness/mineral weight. Found commonly in vehicle cabins.
