Terrazzo is a material made up of fragments of natural stone mixed with cement, the whole is polished to the shine of a natural stone.
Here, in addition to the stone fragments, pieces of Arduenna bottle are used to design the coasters. All the green stones are in fact... recycled Arduenna bottles. Nice recycling, isn't it?
Coasters made by a local craftsman, "Wuidart & François", based in Léglise.
