I have finally placed more copper outside, four pieces. I have placed plant pots over the top to hold them down again, although the copper is thicker than the last lot so I am expecting a different outcome. With the last lot of copper the wind crumpled it and created lines and patterns that I could not predict. I am not expecting this to happen this time so I plan to move the pots around the copper once a week to create some sort of interesting pattern (that was visible in the last lot of copper) from the different levels exposure to the oxygen that forms the dark brownish colour.
I am hoping to have these outside for a month but possibly more depending on how much change happens.
