Yellow stains around fine silver wire embellishments
The fine silver trails on my beads are getting yellow stains around them when I press in a brass bead press. Anyone know why this happens and how to prevent it - very annoying. Using graphite presses does not cause this problem so I'm guessing it has something to do with a reaction between the silver and the brass? Also happens when there is silver foil in the bead - even if the silver foil is encased and does not make contact with the brass - a yellow stain still appears in the area of the foil.
