Guys, you need to control your light. I see a LOT of sloppy highlights on the images posted.
To me shooting glass is like drawing, you need to draw your highlights and shadows and erase unwanted reflections. To eliminate reflections you need black, behind you and the camera and to the side and sometimes above. I avoid any front light sources unless I want to include a specific highlight on the surface. You need to use black cutters to add volume and also white cards to add soft reflected highlights.
As you saw the tent is a bad idea. It doesnt allow you to control the distance of the white surface.
The white (milky) acrylic is a great place to start. Create a small ciclorama with it and shoot light through the back and bottom. But in a controlled manner, dont use to much.
Il try and post an image sample soon of a beer bottle I shot last week.
But try and look through the viewfinder while you direct an asstant to move a reflector and or light etc and see the effect on the glass, that way you will see exactly where you need to put your light controls and what works.
