Thermite type of fusing capability

hello all,

I’m still looking for a thermite Type of fusing capability for .999
Silver. I want to make a moldable paste and use point appropriate
amounts of it to fuse tack sculptural fineSilver together.

my current flame is to big and cold to get fire where I want it, as
I want it.

soldering is not an option.

fusion is essentially a matter of site temperature. the rest is the

I’m researching now for notes, and plan on experiments by this

Hi Jim,

A guy I used to work for used a smallish oxy-acet welding tip to
weld thick (.200") sections of sterling presentation sculptures

Tricky, but it worked. The trick was to get the flame hot as hell,
get a lot of thick paste flux into the area, and then get in, melt
your target, and get back out again fast, before the heat had time to
migrate anywhere. As I recall it, he didn’t do running seams, just
spots. If he needed a running weld, he’d do it in chunks.

As I said, it was tricky, but I can’t imagine a silver thermite
would be any less tricky. (Orders of magnitude more tricky, at a

The tip was something like a 0 or a 00. A for-real steel tip, not a
jeweler’s tip.
