I am looking for chemical or electro-chemical methods of doing
simulated pierce-work. Laser and waterjet cutting have already been
Etching can accomplish this, but you need to use either very thin
stock with a backing sheet, such as another metal laminated or a
resist. If you want to use a thicker sheet, it’s best to etch from
both sides at once. Refer to Oppi Untrect’s book, Jewelry: Concepts
and Technology, for this process. You may find this method preferable
to the PnP method.
In using PnP Blue, or similar, on sterling silver, can the
etchant be a more aggressive chemical than ferric chloride? How
about nitric acid?
Nitric acid destroys PnP acetate. Ferric chloride etches copper based
metals, not sterling silver. Ferric nitrate will etch silver and does
well with the PnP. The nice thing about the ferrics is there is less
chance of undercutting than with the nitric.
Has anyone experienced patterns not adhering to the metal when
using copying services such as Kinko's? (Apparently they are using
Resists, and therefore toners, must be carbon based, such as with
laser printers. The newer “laser” printers don’t use carbon based
toners, and are therefore ineffective as resists. Most photocopiers
still use carbon base toner and are compatible with PnP.
Hope this helps. K.P. in WY
