Just so you have them for comparison, here's what Corning's percentage analysis came up with for SP 87. THe numbers are from Frank Wooleys book, Glass Technology for the Studio:

Measured expansion: 94.9
Given the interest in the actual formula of a glass that seems to have intellectual property value, I deleted part of your post. I hope that is understandable. I don't know currently if the information was even remotely accurate. The 1% lithium is however correct.
Where are we going and why am I in this basket?
