I'm not sure where to find all-metal vials.
However, we have small glass vials with metal caps, and they include a plastic stopper so you can put liquids in the vials.
The first few items in this list come with cork stoppers, instead of metal caps like the ones further down the list:
+glass +vialsWe also have some larger ceramic bottle pendants, but they are about 2" tall, and fairly wide. They would probably not work for what you're trying to do. (If these do sound useful, search our
online store for 28-607 or 28-608 for the high fire or raku-style finishes)
I hope this helps, even though it isn't exactly what you asked for.
