On Chanukkah we light candles/wicks every night. In my experience, those lights are always held in a special candelabra ("Menorah" or "Chanukiya") designated specifically for that purpose.
I'm not sure if such an object is required, but even if is not, it certainly seems to be sufficiently associated with the Mitzva action/item when used, that I'm curious if there are any restrictions on its design, particularly in terms of its material make up. Are there any halachic limitations on materials that can be used (l'chatchila) to make a Menorah for use on Chanukkah?
For example, can one use a Menorah made of ice? How about one of cans, potatoes, or bottles? Perhaps such items are too temporary or too disgraceful to be permitted for use in this context. What would the rules be?
