Another question I'm interested in forming cloissone areas by
electroforming the gold lines rather than by soldering gold wire
on silver, so that I can use photo-resistant techniques direct from
images to form the cloissone areas prior to applying the enamel.
That’s an interesting idea for a new technique. Normally in
cloisonne the wires are fired into a base coat of flux, which does
mean that the border is unprotected and should be bezel set like a
What is the minimum thickness that the gold line must be above the
silver surface for such a technique to be effective?
Standard wisdom says 0.3mm, about 10 thousands of an inch, which
gives room for about 3-4 thin coats. This makes a good depth of
colour without getting too dark. Smaller than this and the colour may
become uneven when you stone it level.
I get most of my silver professionally photo-etched, to 0.35mm (12
thou ish) and then engrave into it. the company I use, Chempix,
Birmingham UK is very very good and the silver has a uniform etch
with good clean borders.
Back to wire thickness for cloisonne - up to 0.5mm, or you can roll
0.3mm to a rectangular shape and place the wires on the thin edge,
gives about the same 0.5mm.
