I gotta tell you I never heard of that. Relief engraving any metal
entails layout, cutting the elements and lastly removing the
background material with a usually flat graver/chisel or a 90 and
then a flat. All the engravers I know of use this process. Lots of
stuff I don't know though.
This is definitely a fine approach, but it has a small flaw. If one
has to produce a number of items with decorated elements, where
consistency required, the only method, which is commercially
feasible, is etching.
And to really appreciate how ignorant the comments, that etching is
somehow a second rate skills, I shall say a few words about the
It starts with preparing a mask of a design. To prepare a mask, it
has to be engraved first, exactly like you described; then a
printing is taken from that engraving, which becomes a mask. In
preparation of a mask, it is not enough just to engrave it. It must
be done with consideration of mordant action. The process is akin to
model making in casting, when model is produced to account for
shrinkage, metal flow and etc. Hardly the skill that can be mastered
in just a few hours, like John was proclaiming.
Engraving vs Etching is like Hand Fabrication of Jewellery vs Model
