How to use Yellow Ocher
Scoop out a small amount
of the yellow ocher onto a small shallow dish or tile (the butt end of
soldering tweezers works well for this), then sprinkle a few drops of water
on the dish near the ocher powder.
Use a little paint brush,
like a #4 sable, to mix the water into the edge
of the powder as needed. You want a thin, but not watery, paint.
It is best applied to joints you want to protect after the
jewelry piece has
been fluxed and then warmed. This way the ocher will dry
application to the precise areas you want it and not run
onto areas where
you intend your solder to flow.
You can also mix a yellow ocher and water solution then put
it in an empty
nail polish bottle and use the bottle's brush/cap to apply
the yellow ocher.
Always rinse the piece before pickling so as not to
contaminate the pickle solution. Always wear eye protection when working
with chemicals, and keep all containers well labeled.
