To get a glass effect, use Object Style 15. To see the swatch names, go to the "Swatch" drop down menu on the upper right corner, and enable the option "Show Names & Notes". You can then apply Object Style 15 to your objects.
If you're looking to create your own glass material, the key is to make a material that has a high value set up for Highlight Sharpness and Brightness, as well as a high value set up for the Reflectivity. You will need to add a reflection map, then increase the transparency value.
