i made a batch of sterling Granules with propane
....discovered that the pickle had been contaminated by
(someone)....so now my granules are copper coated.....so i
made an additional batch.....
Why? Don’t you WANT them copper coated? Seems to me that’s
part of the essential process of granulating silver. Leastways
the way I’ve always done it, specifically involved some nicely
used pickle and intentional iron to copper coat em
deliberately… Thats what makes em granulate…
..changed out my pickle and to my suprise about half of the
granules seem to have an oxide or cuperic coating on half of
the sphere (perhaps were they sat in the little divits in the
The upper half of the granual, exposed to air, get nicely fire
scaled. The lower part, protected by charcoal, stayed clean.
.......Does this mean I overheated when forming?
Overheating? You’ve got to melt em, don’t ya? You’ll find, in
the end, that that fire scale on the grains does not get in the
way. Once you’ve fired the grains on your base piece and
pickled again, this time in non contaminated pickle, please, it
will clean up nicely enough.
