Another day, another fish story.  

So the exercise here is to see what colors I can fish out of the copper. a little more heat here, a little less heat there. In some places I just let it burn right through and the blooms propagated from there. 

The tail was done using metal strips left on top of the copper to act as heat barriers. The exposed areas of course got much hotter and produced the striated effect. Almost like a fish tail, eh?
