glasscherven

Glasscherven is a naturally occurring silicate glass described in various fantasy and fictional science settings as a glassy mineral with distinctive iridescent inclusions. It forms when silica-rich magma cools rapidly, producing a vitreous, brittle material with a conchoidal fracture and a glassy luster. The name, translating to “glass shards” in the setting’s language, reflects its sharp-edged fragments.

Formation and composition: Glasscherven commonly originates in volcanic environments such as lava tubes and fissures, where rapid quenching yields a homogeneous glass. Minor inclusions of iron oxides, titanium oxides, and crystallites can impart color variation, producing shades from gray and green to amber. The material typically has a Mohs hardness around 5 and a density near 2.4–2.6 g/cm³. Under ultraviolet light, some specimens display a faint luminescent glow.

Occurrence: It is found in volcanic regions and basalt fields within the fictional world, often concentrated in shallow outcrops where ancient eruptions deposited glass-rich layers. Economic deposits are rare and generally small-scale, leading to artisanal mining rather than large industrial operations.

Properties: Glasscherven is brittle with conchoidal fracture and a vitreous surface. Edges are exceptionally sharp, and specimens can splinter when struck. The glassy structure limits durability, but controlled heating and annealing can relieve internal stress to some extent.

Uses and significance: In crafts and jewelry, glasscherven is prized for its color range and translucence. Its optical qualities have made it useful in lenses and prisms in some applications, while its resonance with ambient energy is valued in magical or ritual contexts within the setting. Safety considerations center on its sharp edges and fragility.
