I'm enclosing a few bibliographies of information that you may find useful on recycling glass bottles and making moulds. You can request these items through your local library's interlibrary loan dept. I hope you find this useful!
You might try posting your question on a glass artists' discussion board or forum also. The Glass Art Society has a technical forum at http://www.glassart.org/technical-issues.html or go to http://www.warmglass.com/phpBB/index.php for other boards.
