22K/10K Granulation


#1

I am trying to granulate a star pattern using 22K shot on a 10K
disk. I am having a difficult time with unsatisfactory results
and am beginning to wonder if this is not a futile undertaking.
I would normally use a 22K disk, but the client has specified 10K
and I am trying to accomodate. Is this technique possible on
10K? Any suggestions would be much appriciated!

Thankyou! Karen

hi karen,
people have successfully granulated 14k, i’ve never heard of
anyone being successfull with 10k. you are very kind to be so
accommodating. anyone else hear of such a thing?

my suggestion would be to steer the customer back towards 22k.
why does the customer request a 10k disk? the difference in cost
of materials shouldn’t be that drastic. is it for color
difference? suggest silver, 800 or 925, this would work.

best regards,

geo fox

Your granulations will work on 10 gauge… Sure that isn’t what
they meant… In fact that is what one usually does… 22k granules
on 10-12 gauge gold… calgang

Isn’t that rather thick? I thought the gauge of the base should
be approx as thick as the granules – e.g., 20 g granules on 20
gauge sheet. Am I mistaken?

My clients have indeed specified 10K gold for the base of their
piece. Has nothing to do with cost or color, it is a piece that
will afix to a door that my husband is carving with an 8
ft.Hindu god on it. This particular god is always adorned in
gold and jewels, 10 karat gold, not 10 guage gold. My shot is 22
karat and for such a small percentage of the whole piece, I
thought that I could get away with using a higher karat gold
here and would have an easier time than if I tried to use a 10
karat shot. My question is whether or not 10 karat gold as a
base is appropriate with 22 karat gold shot. Would I be better
off using 10 karat for the shot as well, or am I attempting the
impossible by tring to use this process on 10 karat at all? Any
granulators out there? Thanks! Karen >

Sounds like it will be awesome when finished. Will you post
picture(s) please?

If you want to attach the 22k granules to 10k gold, it may be
very difficult to impossible, since the melting point of 22k is
at 1832 degree F and the melting point of your 10k sheet may
range from 1450 to 1500 degree F (depending upon the alloys used
in the 10k sheet).
There are designers who have been successful in granulating 22k
to silver. I will dig up all of my magazines to get their names,
but even in their designs they have been successful in
granulating only a few granules. I am assuming that your husband
is carving the Hindu god Ganesh, with the door knob representing
the ladu in his hand. If I am correct then you can get away with
soldering the 22k granules to 10k sheet. The ladu is a sweet
shaped by hand. If you don’t know what it looks like, just go to
a nearby Indian sweet shop (I hope there is one in your area) and
you will notice that the sweet does not have a high relief. Is
this door for a temple or a private person? I hope this is
helpful, and I will get the designers names from my magazines as
soon as possible

granules can go on 8 ga. and down and up to 12ga. or 15ga.
tops… … Anything else if much too thick to have it work
nicely…(Try it you’'ll like it.) calgang The best is
8-10-12ga. 22 kart gold…It goes on like silk!

Hi. I’m pretty much a novice at granulation but I checked back
on notes I took at a seminar given by John Cogswell. He
specifically said that the granules and back should be the same
karat. At the time I took the seminar I was more interested in
melting silver ;-). So I didn’t ask “why” questions about gold.
Sorry I can’t be of more help here.

Wrong and my fault… I should have said .008 and .010 and .012
etc… Thousands… sorry calgang very fine…

Hi,
I’m not really familiar with granulization but generally as I
remember the beads fuse with the aid of copper solution and glue.
Also the higher purity metals help this to occur being a type of
fusion process. The 10k is not going to have the right suffice
condition for a good bond. So if you were to change the surface
to higher karat by gold plating the piece before you do the
granulization, the process should work? I would think it would
have to be thicker plating than normal but maybe not. After if
you got what you want you could polish through the plate to get
back to the 10k surface if you like the contrast. Jim

Thankyou for all the feedback on my query. I ended up
granulating on a 22K disc that then sits atop the 10K piece. The
door is indeed a carving of Ganesha and is to be installed on a
private home near Lake Tahoe. The gold piece is to be affixed as
his third eye. It has a ruby in the center and diamonds around
the outer edge of a lotus blossom. It has been a fun
collaborative project. We will post photos when it is
installed, probably next week or so. Thankyou all again, Karen
