Q. I have an old cooper Menorah that has a thick loop of cooper wire on each cup to hold the wick. When I light it the flame, as expected turns greenish. Is that a problem since the flame looses its natural color?
A. Horav Shlomo Miller's Shlit'a opinion is that it does not matter and it can be used.
