Earlier versions of this video indicate that the producers were Sidney Goldstein, J. Durst and Wilhelm Nassau, and that the production was done at Wilfrid Laurier University in Canada. One earlier version omits the core-forming process, and is 16 min. long. There may have also been a 12 minute version, but it is not in the library as of May 2003. The earlier versions have records only available in the cataloging module.
The core-forming segment depicts winding hot glass around a core or mold. This possible technique has been superseded by new research that suggests the core was dipped into molten glass or applied to the core as a frit.
Some of these films are included on a 12 inch optical laser disc, "The Corning Museum of Glass, video disc no. 1" (Bib no. 103530) which Sax Communications has indicated is the better quality. The optical laser disc has been digitized.
Edited master and sub master tapes with this title received from Sax Communications. The time on these videos is 14 min. but lacks "Mold-blowing a Roman grape bottle".
Video recording of seven short films previously known as "Corning Museum of Glass Gallery Films", demonstrating seven methods of glassmaking. These films were originally produced to be shown in the galleries of The Corning Muesum of Glass, and were later consolidated onto one videotape, "Techniques of glassmaking". The order on the videotape is not chronological.
Camera, J. Durst and W. Nassau.
Title from video label.
Film segments vary from 1-5 min. Subtitles within each film explain techniques. The following participated in the filmmaking: Karl Schantz, Steuben Glass (mold), Barovier & Toso (dragon stem goblet), Wheaton Village (mechanical press & bottle making), Corning Glass Works (ribbon machine).
Label on video and container incorrectly states that there are 6 segments and the video is 14 minutes in length. The label does not include the segment on "Mold-blowing a Roman grape bottle", which is included on the video.
