Scoria is a basaltic or andesitic, mostly dark reddish-brown colored, vesicular volcanic rock. It has a similar formation with pumice but in contrast, scoria sinks in water due to higher density and the iron content which gives it a darker color. The iron composition of scoria (around 7,5%) is much higher compared to the 1% level found in pumice.

Ekopons Scoria is mostly preferred for ground cover in landscaping. Its earth like color, decoration and drainage properties make it attractive for landscape architects and gardeners. It is also popular as a heat sink in gas barbecue grills, by holding the heat and absorbing grease and liquids.
