How old is your lamp that is not flowing? I was told that the purple look would fade and become blue as time went on and the more you used it.
Funny you should be mentioning this color combo. I have one clear/blue new, never used and one clear/blue that I picked up for $5 bux that appears to have been use very little if any. A very nice blue too.
all of my blue clear globes which I have just dont move much, its not that they flow bad its just they flow poorly. The first one from 94, 96, and 97. I did check around and none in this area or on ebay at the moment.
I thought my blue was the same way. However it takes a bit to get flowing good. Seems that is true with all my midnight globes. I will post a pic once it gets going here. I have it on my desk as blue is my favorite color of all time. I wish I could get a clear/blue 52oz for a good price. God I would love that!
