Perfume bottle:help needed

I’m working on this little bottle and I have some problems with with the glass column that doesn’t have the name on it. It should be a kind of frosted glass. This is my latest attempt but it is not as I want. Does anybody have a tip on this? O yeah it is done with the internal render.

Ligthing and the white cap needs some more improvement. I’ll run a yafray render tonight. But I find the yafray results often not easy to predict and it is very slow for experiments.
I’ll keep you posted
