Hi all I have been following this list with gratitude for a year or
so… learning allot. Being completely broke just now, I found myself
in a bit of a funny position of having to use Platinum, instead of
[buying] gold… Haven’t worked with platinum before mainly because
here in an Indian city, where my studio is these last years,
platinum is not readily available. I have a couple of grams of pt900
left off a 'commercial Diamond ring [I used the Diamond for a nice ring some years back] I want to use the platinum to make a bezel for
an 18k ring. Now, I have no Pt. solder, but going through the Orchid
archives, I read that it is possible to just use a thin piece of the
same alloy just to close-solder the bezel, I have the Little-torch
with butane-oxy, and expecting this is ok. I also have a tungsten
pick. my Question aRe:
will the basic white powder flux [don’t know the name but it is
from the west…] would do ? Can’t get anything else just now.
I heard something about Iron contamination? I do need to roll the
Pt and form it, probably melt it, and roll, hammer, and anneal
… how do I clean the Pt from the Iron traces?
is the normal Sodium-bisulphate pickle ok for Pt?
is the regular ceramic crucible ok for Pt?
5] anything else I need to know…?
Many thanks and here also something perhaps helpful yet non
related… to share. Recently i have improvised a foot controlled
electric zoom for the bench microscope!, It is a real wonderful
technical benefit, as you can keep your hands on the shifting work
and stay in focus. you can make it your self ! If anyone is
interested, I can put on a photo and explain the solutions I came up
