I've seen this site before and it is interesting. I've been aware of this technique and in the past thought it mildly interesting. But as Pyrex and other borosilicate glass gets expensive and/or hard to come by, this process is becoming more and more intriguing. Josh (from this list) is the one to watch for this kind of work. He has some ideas and plans and motivation to do some great work with glass casting.

This is one of the more interesting "mirror making" sites I've seen. http://www.mdpub.com/scopeworks/blanks/index.html He actually makes his own *blanks* by fusing thin glass sheets together, and the process seems to work just fine. Nice website and great photos too. _______________________________________________ Utah-Astronomy mailing list http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Send messages to the list to Utah-Astronomy@mailman.xmission.com The Utah-Astronomy mailing list is not affiliated with any astronomy club.
