This is the bottle neck from the broken wine bottle displayed in a different thread.
The tabletop is glossy black acrylic. The glossy silver background not in the scene is bent around the tabletop to generate the desired shadows and highlights reflected in the tabletop. Two medium continuous-light lamps with diffuser socks attached were used -- one on the right side and one on the left side.
EDIT: I was unhappy with the lack of separation between the foil and its reflection in the first photo. So, I reworked the post-processing in the second photo. The primary difference in the post-processing is that I converted to monochrome using a color filter in the first version, whereas I desaturated the second version.
