The Making of Glass

Yesterday I was on my computer almost all day since I woke up. I was working on multiple things, and one of them was figuring out how to make glass in Maya. I had difficulties with the setting but I finally got it at the end and I am still seeing what the glass texture can do.
This first image is my first test, as you can see it was too dark.

The following are more test trials later on that day after figuring out the settings.
