Hmm....some sort of glass. Nice smooth textures. I think I would have shot this with the bottom completely out of the frame and focused squarely on the glass patterns and light.
Moderately striking image - though the emphasis is more on light than texture. I think with shiny smooth subjects the best way to show the texture of them is to reflect light from them, rather than passing light through like this - which doesn't really show much of the surface at all.
