Mokuma and Shakudo problmes

After reading the posts about the problems with Mokuma and Shakudo
leaching out, I have been concerned about their use in earings which
are on a post. The alloy will be in direct contact with a person’s
ears, and I am wondering if this will l cause a problem. Has anyone
had any experien ce with this? These are wonderful materials, but
from the posts which have been appearing on Orchid I am worried
aboout their use in anything which will be in direct contact with a
person’s skin.
