What was that recipe for darkening silver again?

Some weeks ago someone posted the name of a garden chemical
which could be used instead of liver of sulfur for creating
silver patina. Does anyone remember the name of it?

 a garden chemical which could be used instead of liver of
sulfur for creating silver patina. Does anyone remember the
name of it? From the post by Jestre2U (I saved it for
reference):. 

I purchased: ORTHO–lime sulphur spray (16ounce dark green
bottle) in concentrate. It cost me $7.99, cheaper everywhere
outside of Nevada!

I put about 1/4 cup of water + one small squirt of Ortho. And
heated----ON THE STOVE!!! I had to appologize to my wife all
day for stinking up the house! Now I know why they say to do
this outside. It produced a beautiful blue-black patina on
sterling silver. If you put it in the solution for only a few
seconds, it comes out a beautiful reddish-orange rainbowish sorta
color. It only takes a minute or two in hot(not boiling)solution
to achieve a dark patina.

Thank You to all who suggested this–you were RIGHT!!! Tom

G’day; Can’t tell you a brand name, but the chemical is sold as
lime-sulphur, more properly known as calcium sulphide, or
polysulphide; smells like rotten eggs, and is used as a
fungicide on garden plants. It is slowly being supplanted by
more sophisticated fungicides. To use, dilute it about 3:1
with water, and add a little household ammonia. Use it warmed,
with your work completely grease-free and very clean. Don’t try
to store it - it is very cheap and won’t last anyway as it is
oxidized in a day or two to calcium sulphate. Use it outside
and don’t inhale the stuff more than can be helped. The gas
given off is hydrogen sulphide and is as poisonous as carbon
monoxide with much the same effects: it combines with haemoglobin
in the blood and inhibits the uptake of oxygen. But cheers
anyway,

As an instructor of Confined Spaces, John is correct about
hydrogen sulfide being deadly, except its more deadly than carbon
monoxide. Permissible level is 35 PPM for carbon monoxide in an 8
hour period. 10 PPM for hydrogen sulfide in same period. 4000+
PPM deadly in minutes for CM, 2000-2500 PPM for HS. The big
problem with HS that I tell my students is that sure, you can
smell the foul rotten egg odor and that should be a tip off as to
what you’re dealing with, but it quickly desensitizes your sense
of smell and you don’t think that it is still present. It is
still there and can be deadly. Yes, the effects are about the
same as CM, headaches, feel bad, eye & respiratory problems, but
you might not attribute the effects to CM or HS thinking your
getting a cold/flu. Ventilation, ventilation, ventilation!

Get a tube bender from any hardware or plumbing store. You
should beable to find one in the size that you need.

AS for what it is. It is a coil of stainless steel wire that you
put the tube in the hollow then it keeps the side walls of the
tube from collasping. Rob at the sentry box
