I recently found a photo of an amazing vase made in Shotai Shippo technique. It is a type of plique a jour enamel, but it’s done slightly different, than traditional plique a jour that I’ve heard about. The cooper plate is covered with clear flux, burned and then gold or silver wires are glued to the surface and filled with transparent enamel - exact same as traditional cloisonne.
But after the process is complete - copper is dissolved in the acid bath and there will be only glass. Looks very beautiful, as wires are very thin and it creates an additional lightness and transparency.
So I was wondering:
- If I need to use counter enamel - how I would remove it?
- What type of acid would be appropriate to remove copper and how to protect the face of the piece from acid? And if I protect the front - would the back side of enamel impacted by acid when copper starts to disappear?
I wouldn’t risk to do a vase, but small jewelry piece in this technique would be nice. I and kind of excited that I don’t have to pierce hundreds of cells in the sheet of metal (night mare). In general I understand cloisonne technique and this method would be much easier to implement if I understand copper removing part.
