I am aware that this may not be viable as a way of manufacturing these mirrors in a cost effective way, compared to grinding. I have a backup plan in place which would require 1 or two mirrors to be made through this process, after which I could deal with the mirrors the old...
I need to make very large, accurate quartz/Borosilicate mirrors for telescopes. Grinding them precisely seems like it would be to much of a hassle to get right, so I would like to make a mold to pour-an-view. It's possible no matter what that I'll need to do SOME grinding, but I would like to...
