I haven't been able to find anything exactly as you are describing. I did find a video from the 1930s showing footage from a factory in Denmark.

  Holmegaards glasværk.
Title: En dag i Holmegaards glasværk [videorecording] / produced by Kongsbak & Cohn.
Publisher: [S.l.] : Kongsbak & Cohn, [1936?]
Description: 1 videodisc (36 min.) : si., b&w ; 4 3/4 in.
Notes: Title from title frame.
  A record of the many operations of Holmegaards Glasværk, which was a small firm making primarily hand-blown glass, but also had an O’Neill machine with 3 molds for milk bottles. Included are views of the factory exterior, making tools and molds, making pots and changing the pot, glass blowing and working, finishing techniques, handpressing, and the automatic bottle machine. The man at the beginning of the picture, who is visiting an old lady at her door, and then subsequently shown in the designing room, is Jacob E. Bang.

 Would this be what your friend described or was he/she talking about a studio artist? We checked with Studio staff and other our video cataloger as well, and no one was aware of a video such as you describe.  Let me know if you have further details I could use to narrow down a search.  For instance, did your friend view the video here at our library? On the web?
