Hello Mike Mathews, You asked: Does Liver of Sulphur break down
after use? The answer is Yes. It’s best to mix it up in small amounts
for immediate use. You’ve learned that the solution doesn’t store
very well. It also “wears out” with ongoing use.
Check the archives for Charles Newton-Brain’s discussion on liver of
For an alternative, John Burgess posted to go to your friendly
neighbourhood garden shop and buy a little bottle of 'lime sulphur’
which they sell for treating fungus on shrubs. It is in fact, calcium
polysulphide, and has exactly the same properties as liver of
sulphur, which is potassium polysulphide and of course rotten egg.
All give off hydrogen sulphide, hence the disgusting smell. Use the
calcium salt exactly as you would ‘liver of sulphur’
I followed John’s suggestion and use the lime sulpher, diluted about
1:1 with hot water. The resulting warm solution gives me good
patinas, but you may like a more dilute solution for better control
over the process.

recent memory! Excitement is high on campus with the first football
game this Sat. evening.
