Metal ink smoke, Please help.

Hi there all,
I have been following the really cool tutorial of making ink drop in water by Blenderdiplom.
I have an amazing simulation, but I have a little problem of changing the material, could some explain how I can make the ink droplet looking metal.
The usual material nodes for metals doesn’t seem to work as smoke uses volume.
Any advice on how to setup the nodes would be greatly greatly appreciated.

Here is the tutorial I have been following:

Thank you in advance.

Anyone out there have this problem?

only problem is not knowing - “turn smoke into polys, then shade”
study well

holy moly, of course, you say one thing and it’s like someone opened up my brain and shouted mesh you fool mesh itttttt.
Thank you, I don’t know why I didn’t think of that, this solves everything.
