One customer of mine that over the years has used over 300 of my blanks, for
saving voices of those who are the last to speak certain dialets, and to tell stories, and turn the Phonograph into characters. This is a vidio explaining his various projects, Pablo Helguera. There were very little blanks of regular white or brown, most were pink, green blue red ect. http://www.smac.us/2010/04/25/pablo-helguera/ This is something about brown wax blanks you might find interesting, that Jonas Aylsworth said. Aylsworth looking at blanks in a court case from page 30 and 31. "Yes, I can identify these as being made prior to 1893, because of the manor of making the blanks, as seen in 4, 5, and 6 especially, must be very old because when cut into it is seen that there is a change of color, the outside being a salmon color and the small portion of the interior, or middle is the original color of the cylinder. This change in color, I am familiar with and know the cause to be the gradual absorption of oxygen, which causes the stearate of iron which the record contains as an impurity derived from the iron kettles, to change to the ferric or higher oxidation stage, which produces a brownish or salmon color. It would take years for the action to penetrate the depth which it has in these two records. I observe that since the records were cut to take samples for analysis early in January up to this time, there has been no perceptible change in the lighter interior portion; the age of a composition of this kind could be fairly accurately determined by the depth of discoloration. These records are the same composition and were manufactured previous to 1893 by the Edison Manufacturing Company and Edison Phonograph Works. And which were molded into records and blanks and sold commercially _________________________________________________________________ The New Busy is not the old busy.
