Some pictures of Laura's lamp after applying the green patina, I think it works quite well.
The top faze from green to copper came out a lot brighter than the bottom but applying this particular chemical is not an exact science.
I found this old wall mounted loud speaker whilst at the scrap yard and thought with a little bit of work it may make a nicer lamp shade than a gramophone horn?
The insides of the speaker could be placed on top to produce a more streamlined shape
The whole lamp shade is only suited for an up light but it does have a space to let some light out and a vent for the heat......
