REAl glass?

REAl stands for Rare Earth Aluminum oxide. This is a type of glass made at NASA. It's interesting because they trial the experiment by floating samples in an electrostatic levitator. See floating molten glass!

Lightweight glass?

Now I really got excited about this because it sounded perfect...I mean what casting artist wouldn't want a lighter weight glass? It is however just a smart environmental push to get manufacturers to use less glass in the design of their bottles. Good idea chaps but doesn't help me.

WRAP are the smarts behind this good idea. Read more about their Glassrite campaign
