Thanks for correcting me - I have not been there since I was wee lad. I was not sure if they are using Aluminum or Silver - I could not recall.
I was also emailed by someone named Jerdal who took the time to check the glass comment with a PhD. relative. I appreciate the correction. I do have a text "Quasicrystals: a primer" by C. Janot that goes into some detail on the matter. I did not bother to double check that either. As I said, I had no reason to doubt Scientific American and never noticed a retraction on the matter. I only thought it might be of interest in passing. Like they say, "always check your references".
