Glowstone®™ 25

Glowstone® 25 Glow In The Dark (Photoluminescent)

GLOWSTONE® is a synthetic aggregate, based on Luxilum™ pigment and synthetic resin. When exposed to light sources, the photoluminescent pigment within GLOWSTONE® becomes chemically excited and will afterglow (i.e. glow in the dark), initially very strongly, then reducing slowly overnight. The glow is best seen in a dark area, where ambient light sources such as streetlights and moonlight are absent.

GLOWSTONE® is specially formulated from non-shrinking, extremely hard polyester for use in Concrete, Pavers and Terrazzo products as an exposed aggregate.

GLOWSTONE® enhances SAFETY by marking the pathway in Low Light Level conditions.

In daylight the GLOWSTONE® has an Off-white colour and can be supplied in after-glow colours of Yellow-green, Aqua blue and Sky blue.


GLOWSTONE® is easy to use in an homogenous mix or as a surface topping for concrete paths, steps and terrazzo floors. GLOWSTONE® can be used as an additive into pebble paving or loose laid into gravel paths. GLOWSTONE® looks and acts like quartz, yet is able to glow in the dark to provide that special night-time effect.

Glowstone ® in Concrete tiles

Added to the surface pour of the concrete tile, it can be exposed by lightly blasting the cured tile surface.

Glowstone ® in Terrazzo tiles

In Terrazzo tiles the GLOWSTONE® is pressed into the surface of the uncured tile. After curing, the tiles can be ground and polished as normal.

Luminance Strength of GLOWSTONE®:

GLOWSTONE®can be manufactured in a range of Photoluminescent pigment strengths. Grades with higher pigment content have a higher cost but also have stronger initial after-glow and will also have a longer duration of glow.
