this question I have is for the experts in metal alloy ingot making
I have been having a lot of problems cracking of the metal, the
minute I start trying to work it. the metal i have is 14k Yellow, I
know I have used it a few times over, with out adding fresh metal to
it and so I believe it is at it’s end of use as is. for 3 days on and
off I melted adding some new material to it and the minute I would
start forging/rolling to square wire it would crack like crazy, a few
times I repaired by fusion, and it worked for a 2 grooves down the
line, but would start cracking again. and this is with annealing down
I noticed that when i was quenching as normally I would 14k Yellow
in alcohol it was cracking,so I started waiting for it to cool down
almost completly before quench, it helped.
I know the best thing to do is give it up and turn it in for
refinning. but with that I will be loosing out finnancially.it is an
ounce of 14k.which is worth a certain amount given in, and to
replace it I will probably get only half an ounce if not less.
I know that there are ways to fix the problem of cracking when the=
alloy is too abused/used. even with new metal being added it did not
fix the problem, but I am thinking that I added only a quarter of
the amount needed to replenish(that’s all I had). so my question is
to take care of the brittle metal if I were to add the same amount
(1 ounce)or more of new metal to the batch would that solve the
cracking issiue or would it make thewhole batch bad and brittle?
My follow up question in this is, in the US. where would one be able
to buy pure gold in Bullion form? not the refined casting grains.
was there a place that sold smaller tablets/bullions? I remember
back home and europe it was available from any bank, you could walk
in and purchase a smal amount of coin or tablet of pure gold. most
goldsmiths did that who made their own alloys.
thanks for your attention, any advice would be appriciated, hoover
and strong, stuller, United metals, PM west, anyone from the
refiners advice is more then welcome too.
