I don’t know anything about the beryllium dangers or problems but
cloisonn� wire is fine silver with doesn’t oxidize, is thin and
short. It bends easily to go around corners ad bends. It has a higher
melting point than sterling. A round wire will not make as nice of
bends so unless you want the copper color or the width go with the
fine sliver cloisonn� wire. It’s hard enough to be a beginner without
making problems for yourself with tools or materials. The wire is
inexpensive.
