Rojo Alicante is quarried in a bedrock quarry near Novelda, Spain. The white crystals and veins in this stone are concentrations of white and clear calcite. It is a common characteristic for this stone to have voids in the raw material. Before it reaches the polishing stages, these voids are filled with a polyester resin. Depending on how deep the void is, the resin may shrink as it dries, which will leave the surface of the filled area slightly lower than the rest. This does not affect the durability, maintenance or beauty of the stone. Finally a mesh backing is adhered to the back of the stone to ensure safety while handling and fabricating the slab. There can be noticable variances between pieces, so it is important and recommended that a range of this product be viewed before finalizing a purchase.
