Another glass producer is Schott glass: http://www.schott.com/english/index.html

Dear all, I knew about the vicor process, but there is still too much sodium in the glass at the end. I found some papers about preparing a glass in a hot press: Ceramics International, 23 (1997) 291-296.

Production of pure quartz glass is done by Heraeus: http://www.heraeus.com Corning produces fibres: http://www.corning.com/opticalfiber/products__services/ Or try: http://www.calphotonics.com/optic1/ If you go to google.com and search for high silica fibres you will get a mountain of results!

Has sombody any idea if there has already been tried difussion of metals into silica-based glasses? And if it has worked out? Any helpful internet-sites and publications are welcome.

Dear Bugman, the problem with Pt-crucible is that it melts above 1736°C!!!!!!!! Meanwhile we tried some induction melting and that seems to work out quite good.

We already thought of the H2-O2 flame, but you need good refractory for the walls, and the Pt melts above 1736°C!!!!
