House of blue crystals
This sounds really fascinating:
British artist Roger Hiorns covered everything in an old condemn flat with blue crystals:
The walls and ceilings are covered in blue copper sulphate crystals, their rhomboid facets glinting in the gloom. Silvery shards of cold light spangle and wink and beckon. Every surface is furred and infested; big blue crystals dangle like cubist bats from the light fittings. Little wonder the flat has been abandoned: you’d move out, too, if the crystals moved in.
Hiorns began by reinforcing the walls and ceiling, and tanking the flat with plastic sheeting. Then 70-80,000 litres of copper sulphate solution was pumped in through a hole in the ceiling from the flat above. Weeks went by, until the temperature of the solution dropped, and the crystals began to precipitate. Finally, any remaining liquid was pumped back out, to be recycled by the chemical industry.
I’d imagine it’ be like stepping into some sort of alien planet in one of those horror sci-fi movies.
