On a recent visit to Los Angeles with the Art of Rome's Provinces Seminar (supported by the Getty Foundation), I enjoyed discussing artists and art production with one of the curators at the Getty Villa, Ken Lapatin. During this, we talked about the Getty Museum's YouTube Channel which has playlists devoted to the making of art and also their conservation projects. This is a fantastic resource, their films covering the following crafts: bronze casting, mosaic (Byzantine materials and making), pottery (making Greek Vases and a Moulded Athenian Vase), glass (Core-Formed, Free-Blown, Mould-Blown, Mosaic, Cameo) and silversmithing (Sculpting in Wax, Making Moulds, Casting, Hammering).
All of these are fascinating but there are some whose concerns fit particular well with the Art of Making project and our own videos:
