I only use patina every now and then, but I 've never been
disappointed with it.
Here is what I usually do:
I never polish completly my work before patination.
Sometimes I even reanneal and pickle it at this stage, so I have a
nice white greasefree paper-like surface for the patina.
Once I dipped the piece in liver of sulphur and rinse it, I burnish
the patina into the metal in the barrel (with steel shots
demineralized water and lubricant).
(It is good to clean the shots and barrel afterward.) Then I seal the
colour with homemade beeswax-turpentine paste.
