Walter Danz of G Danz & Sons, Los Angeles, is one of the few dwindling number of craftsmen making glass eyes. He learned his trade by serving a 10 year apprenticeship under his father, Gottlieb Danz, a German-born American immigrant, and produces one artificial optic every fifteen minutes. His products are blown from a special grade of glass tubing imported from Europe. The tubes have a light frosted appearance, and might be any one of several grades of lime glass produced in the US; but, Danz has been unable to purchase American-made tubes which would yield desired eye-colour effects with the metallic-oxide pigments that he has been taught to use. Tubes are selected by diameters in relation to the eyes that must be made, allowing more than sufficient glass in order to permit dimensional corrections later on.
