Following up my last post, I wanted to turn to bird houses made of stone. These were designed by Italian designer Raffaello Galiotto in cooperation with Arredo di Pietra. I learned about them from a nifty site, Stone-Ideas.com. Galiotto and his design team also produced houses for other beasts, including dogs.
The houses are made of travertine, one of the most commonly used building stones in the world. Because of the potential for diseases, each house has been treated with a protective coating. Known as the Redoxstone system, it is made of nano-particles of titanium dioxide or titanium (IV) oxide. According to the Stone-Ideas web site, ” This naturally occurring oxide of titanium can oxidize oxygen and organic materials directly giving it sterilizing, deodorizing and anti-fouling properties.” I imagine that this will make the birds happy.
