Gold Delta 1975 to Terconar paving by Jordi Ros Bofarull. An industrially produced terrazzo paving that incorporates colour applications to form different patterns. The advances registered in the production technique, rather than the product itself, permit results wich had only been possible with artisan production systems in the past. The jury said: "For the importance to our public environment of these industrially produced objects. And for the imaginative development of production techniques to give this product possibilities of variation, identity and beauty until now reserved for handmade products."
