Meet my New Copper Bowl – Troika

Yesterday I finished my new copper bowl and I named it Troika, which is Russian for a grouping of three.  Along with the photos, I wanted to share a list of the steps it took to achieve the finished bowl.

• Sketched out ideas and ordered materials
• Sinking, bouging, and planishing the bowl – there were many repeated steps in this part and annealing was in there as well.
• Decide on shape to pierce out of bowl and how many holes I wanted.
• Fold copper squares for outside shapes.
• Pierce outside shapes to cover the holes in the bowl

  Pierce bowl

• File all the cut edges and bowl edge
• Fold smaller inside shapes
• Pierce and file inside shapes
• Form all six of the fold formed shapes and re-file edges as necessary
• upset edges of the shapes (hammer texture)
• Line everything up, tape it tightly, and drill holes for the rivets
• Final sanding and scotchbriting
• Use liver of sulfur to oxidize all the shapes and bowl
• scotchbrite
• rivet together
• scotchbrite
• Take photos

So you see there are a lot of steps even with the omission of each individual step in the bowl forming stage.

PS: It looks like I left out the steps of making the base…oops!
