Eco glass cleans itself with Sun
go to article

Imagine a world where there will be no more cleaning of window glass panes! This is achieved by depositing an extremely thin coating of titanium oxide on the glass surface, which will react with the surface dirt in the presence of ultra-violet radiation (plentiful in sunlight). With the subsequent arrival of rain, the surface dirt is easily washed away in a uniform manner. Now imagine if this technology can be applied to outdoor sculptures or heritage structures!

  1. More information on the titanium dioxide coating technology for self-cleaning glass in the BBC Radio 4 programme, Material World, which also touched on the other (non-paint) uses of titanium dioxide - for water purification and absorbing air-borne pollution (see previous post here)
