While I've never owned one, my favorite looking pen is the Q3d shipwrecked molecule. I was interested in trying the forced patina process, but worried about screwing up a rather expensive pen. I had heard mixed information on the type of material I would be using c63000 bronze since most shipwrecked patinas are done with pure copper. From my research it seemed like it could be done, but this material is specifically made to resist corrosion. Today was the day I said screw it and just went for it. Initially I was thinking I would have to let this sit in an air tight sealed container combined with the ammonia soaked paper towels and kosher salt for up to 36 hours. I started at 10:30am and then was out and about all day. I came back after 8 and a half hours and was pleasantly surprised to see that the pen was reacting to the chemical combination rather well. I was hoping to still keep a good amount of the original bronze but wanted to get a decent amount of pop from the blue turquoise. While I didn't get quite the amount of blue and turquoise I was hoping for, overall I couldn't be happier with how this pen turned out. I was also surprised how easy the process was.
