In 2011 Porcel collaborated in the reconstruction of the Shrine of the Bab in Haifa (Israel), considered of "exceptional value" in the list of World Heritage by UNESCO.
It took three years of research for Porcel to develop a tile with guarantee resistance to adverse weather conditions, such as acid rain, sand storms and temperature differences, maintaining the color of the pieces.
The 12,000 pieces of 120 different sizes and shapes were coated with 26kg of 24K gold, were tested under rigorous cycles which predicted a guaranteed life of 200 years minimum, higher than the original tiles, that lasted 40 years.
