no need to roll it, planishing it will thin it well.
One can certainly forge it down but there is absolutely no reason
not to roll it, how do you think the solder sheet you buy is made?
if you anneal it it will more than likely melt down. and you will
probably firestain it as well as drawing the zinc - depending on
what form you used- out of the compound.
Nonsense it just needs a little lower temperature to anneal than
sterling. As to drawing the zinc out, that is nonsense as well. Zinc
will not vaporize at temperatures below 1665 F, which is way above
any silver-copper-zinc solders melting point.
just put a piece of thin-ish leather on the anvil and planish with
an 8 oz. hammer - if not heavier depending on the size and depth of
the ingot of solder you created.
You will have a hell of a time doing much reduction in thickness
planishing on leather.
You could cover with CUPRONIL (a 4S Labs product- indispensable on
the jeweler's bench for flux and firescale prevention in one..)
This is the only reasonable thing you have written in this post.
and heat it just to a soft red..not glowing- that may help further
incorporate the metals by smoothing the surface- almost getting it
to the liquidus stage but not quite that far as it may just seperate
the components as opposed to bonding them..
Where in the world do you come up with this stuff.
