synthetic photoluminescent aggregate


GLOWSTONE is a synthetic aggregate, based on Luxilumä Photoluminescent pigment.   When exposed to light sources, the particles within GLOWSTONE become chemically excited and will afterglow, 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 and Terrazzo products as an exposed Aggregate.

GLOWSTONE contains no fillers and is physically stable. 


GLOWSTONE is easy to use in a 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 does not discolour and looks and acts like quartz..
