Practice soldering?

Have no idea how much per gram to buy ready made, but would hazard
a guess that it would include a manufacturers overhead. 

There is overhead and there is a highway robbery. If you have a scale
weigh something and calculate price per gram. Just do yourself a
favor. Sit down before you look at final result.

to address your other points:

You have to decide what do you want to do.

If you want to learn to work with precious metals, you start with
small pieces made out of wire or strips.

If you care about production efficiencies, you have to have bank
account to support it. It is either one or the other.

If all you want to do is to pass your test, than you have to
concentrate on that and forget everything else.

Have you ever done mountain climbing? If the answer is no, you
should give it a try. You will quickly learn the hazards of “not
limiting oneself” strategy, and benefits of baby steps in pursuing a
goal.

There is overhead and there is a highway robbery. If you have a
scale weigh something and calculate price per gram. Just do
yourself a favor. Sit down before you look at final result. 

Exactly, I haven’t been in the industry long enough to know what is
a good price.

For example yesterday I bought $75 AUD worth of silver, one piece of
sheet 60mm x 100mm x 1mm, and a piece of 4.5mm square stock gauge.
Whether that’s a good price… I simply don’t know.

to address your other points: You have to decide what do you want
to do. 

It’s early days yet, so I don’t want to limit myself, by locking
myself into one technique… I’ll keep the blinkers off for a while
:wink: I do like Mokume Gane, and am gearing for that, I also like
sculptural pieces and making things with my hands, the Mold-a-wax is
closest to clay that I can get, and working with a clay-like
substance is a great way to get some organic shapes. I do like making
bands by rolling, and soldering (this is the most convenient way to
do this imo)

If you want to learn to work with precious metals, you start with
small pieces made out of wire or strips. 

The nature of what I want to do, uses base alloys and base metals
along with precious metals. And now with the new Australian standards
I can hallmark the pieces, and let the client know what’s exactly in
the piece.

If you care about production efficiencies, you have to have bank
account to support it. It is either one or the other. 

With respect, this is where you can get clever. A few years ago, I
was looking at home metal casting, and looking at the daunting
prospect of buying or making a furnace from scratch. All of the
literature came from America, and the suppliers were also American
based. I decided to go electric, after failure and the realisation
that electric radiant coil melting is very slow, went to gas.

I can make you a furnace that will get to the melt point of platinum
(not the flow point, it’s not useful for platinum), therefore any
metal or alloy with a lower melt point can be melted. The cost of the
furnace body is about $30-$50 AUD(depending on how good a scrounger
you are), and will melt 2kg of metal in 10 - 15 minutes.

Being clever can save you money. The full setup of the above furnace
would set you back about $200 AUD, however a commercial unit that
can do the same will cost you over $1000 AUD.

If all you want to do is to pass your test, than you have to
concentrate on that and forget everything else. 

Of course I don’t “just” want to pass my tests, but it’s very
important that I do.

Have you ever done mountain climbing? If the answer is no, you
should give it a try. You will quickly learn the hazards of "not
limiting oneself" strategy, and benefits of baby steps in pursuing
a goal. 

Having a fear of heights, it’s highly unlikely that I would ever put
myself in the position of mountain climbing. Also there aren’t what
you call mountains in Australia.

I see your mountain climbing and raise you martial arts. Having done
some weapons based martial arts and came to the realisation that
flexibility can mean the difference between life an death. Being
flexible and able to adapt is quite important.

I’m not going to “box” myself at this early stage, it’s better at
this time in my career to be flexible, and take a few risks.

I have some alloy formulations that I want to work on and patent,
should I not extend myself and use the new alloys that I make?

If I come up with something revolutionary, should I sit on it and
never let it see the light of day because I’m new to the industry?

I just don’t understand why I shouldn’t try to extend myself, and
let’s face it I’m not a spring chicken.

Practise many kinds of soldering. Join lead-tin pewter with pure
tin. Soft-solder or silver-solder iron, steel, copper, brass. Solder
silver, gold and platinum correctly. Find the limitations of Wood’s
metal and solders that melt at around 100*C.

Learn welding with an oxy torch, a stick welder, TIG,
pulse-arc…and lazer if you’re lucky.

These are all means to an end. They share common principles. Knowing
more is not a handicap and expanding the horizons back 1000 years is
the same as peeping into the future because expansion is sphereical.

Charles…it’s a wonderful exploration. Leonid…you did it in a
previous life and are now more focused!

Regards to you all, Alastair

Practice Soldering observation.

Please excuse my tardiness in reply, as I am behind in my reading.

At T.I.J.T., Paris Texas There were two approaches to the " "
practice with Bronze or practice with Gold question " which might
shed some light. This is my experience.

The first group which practiced for three semesters with Brass and
then Silicon Bronze, cast, finished and stones set to J.A. standards.
They then worked the last semester in 14 K. Yellow and White Gold
with some Platinum as well, EXCLUSIVELY ! This group was working
toward a 4 semester program leading to an associate degree in
Jewellery Technology. They finished up taking the J.A. Bench
Technician test.

The second group was comprised of students training for 1 semester
to take and complete the J.A. Certification test for Bench
Technicians. They worked in 14 K. Yellow and White Gold with some
Silver, Exclusively. I do not know if any Platinum was used as I was
a member of the first group.

We all took the same J.A. Certification test under the same
conditions and at the same time.

At graduation, 5 people received all their certifications and
degrees. 4 persons were from the first group who had practiced 3
semesters with non precious metals. 1 person was from the second
group who had practiced with precious metals entirely.

As I remember, there were 35 people ( approximately ) in a total of
both classes. And both groups paid for their personal Gold loss. The
curriculum was not the same for both classes in the precious metals
phase.

Anyone who wishes to learn more should contact the staff at T.I.J.T.
