Here is the white-like glass in the lamp....

You will see below a lamp I completed today. In the pictures of the lamp, I could not get the "bone" colored glass to look in the photo the way I was seeing it. Surprise! I waited until later in the evening and went to check on my lamp. The colors had changed from before and the design I was speaking of was shining through in this light. I captured it on the camera. SO - when you look at the lamp below, think of this type of glass inside, the circular designs rolling through.
